+# Using the DeDRM plugin with the Calibre command line interface
+
+If you prefer the Calibre CLI instead of the GUI, follow this guide to
+install and use the DeDRM plugin.
+
+This guide assumes you are on Linux, but it may very well work on other
+platforms.
+
+## Step-by-step Tutorial
+
+#### Install Calibre
+   - Follow [Calibre's installation instructions](https://calibre-ebook.com/download_linux)
+
+#### Install plugins
+  - Download the DeDRM `.zip` archive from DeDRM_tools'
+     [latest release](https://github.com/noDRM/DeDRM_tools/releases/latest).
+     Then unzip it.
+  - Add the DeDRM plugin to Calibre:
+     ```
+     cd *the unzipped DeDRM_tools folder*
+     calibre-customize --add DeDRM_plugin.zip
+     ```
+  - Add the Obok plugin:
+    ```
+    calibre-customize --add Obok_plugin.zip
+    ```
+
+#### Enter your keys
+  - Figure out what format DeDRM wants your key in by looking in
+     [the code that handles that](DeDRM_plugin/prefs.py).
+     - For Kindle eInk devices, DeDRM expects you to put a list of serial
+       numbers in the `serials` field: `"serials": ["012345689abcdef"]` or
+       `"serials": ["1111111111111111", "2222222222222222"]`.
+  - Now add your keys to `$CALIBRE_CONFIG_DIRECTORY/plugins/dedrm.json`.
+
+#### Import your books
+  - Make a library folder
+  ```
+  mkdir library
+  ```
+  - Add your book(s) with this command:
+  ```
+  calibredb add /path/to/book.format --with-library=library
+  ```
+
+The DRM should be removed from your book, which you can find in the `library`
+folder.

+# Changelog
+
+List of changes since the fork of Apprentice Harper's repository: 
+
+## Fixes in v10.0.0 (2021-11-17):
+
+- CI testing / linting removed as that always failed anyways. The CI now "just" packages the plugin.
+- ~Support for the Readium LCP DRM (also known as "CARE DRM" or "TEA DRM"). This supports EPUB and PDF files. It does not yet support Readium LCPDF/LPF/LCPA/LCPAU/LCPDI files, as I don't have access to any of these. If you have an LCP-protected file in one of these formats that this plugin does not work with, please open [an issue](https://github.com/noDRM/DeDRM_tools/issues) and attach the file to the report.~ (removed due to a DMCA request, see #18 )
+- Add new Github issue report form which forces the user to include stuff like their Calibre version to hopefully increase the quality of bug reports.
+- Issues with PDF files in Calibre 5 should be fixed (merged [apprenticeharper/DeDRM_tools#1689](https://github.com/apprenticeharper/DeDRM_tools/pull/1689) ).
+- Fixed tons of issues with the B&N PDF DRM removal script ignoblepdf.py. It looks like that has never been tested since the move to Python3. I have integrated the B&N-specific code into ineptpdf.py, the original ignoblepdf.py is now unused. Fairly untested as I don't have any PDFs with B&N DRM.
+- Issues with Obok key retrieval fixed (merged [apprenticeharper/DeDRM_tools#1691](https://github.com/apprenticeharper/DeDRM_tools/pull/1691) ).
+- Issues with obfuscated Adobe fonts fixed (fixes [apprenticeharper/DeDRM_tools#1828](https://github.com/apprenticeharper/DeDRM_tools/issues/1828) ).
+- Deobfuscate font files in EPUBs by default (can be disabled in the plugin settings).
+- The standalone adobekey.py script now includes the account UUID in the key file name.
+- When extracting the default key from an ADE install, include the account UUID in the key name.
+- Adobe key management window size increased to account for longer key names due to the UUID.
+- Verify that the decrypted book key has the correct format. This makes it way less likely for issue [apprenticeharper/DeDRM_tools#1862](https://github.com/apprenticeharper/DeDRM_tools/issues/1862) to cause trouble.
+- If the Adobe owner UUID of a book being imported happens to be included in a particular key's name, try this key first before trying all the others. This completely fixes [apprenticeharper/DeDRM_tools#1862](https://github.com/apprenticeharper/DeDRM_tools/issues/1862), but only if the key name contains the correct UUID (not always the case, especially for keys imported with older versions of the plugin). It also makes DRM removal faster as the plugin no longer has to attempt all possible keys.
+- Remove some additional DRM remnants in Amazon MOBI files (merged [apprenticeharper/DeDRM_tools#23](https://github.com/apprenticeharper/DeDRM_tools/pull/23) ).
+- Just in case it's necessary, added a setting to the B&N key generation script to optionally allow the user to select the old key generation algorithm. Who knows, they might want to remove DRM from old books with the old key scheme.
+- Add a more verbose error message when trying to remove DRM from a book with the new, not-yet-cracked version of the Adobe ADEPT DRM.
+- Added back support for Python2 (Calibre 2.0+). Only tested with ADEPT (PDF & EPUB) and Readium LCP so far, please open an issue if there's errors with other book types.
+- Begin work on removing some kinds of watermarks from files after DRM removal. This isn't tested a lot, and is disabled by default. You can enable it in the plugin settings.
+- If you're using the [ACSM Input Plugin / DeACSM](https://www.mobileread.com/forums/showthread.php?t=341975), the encryption key will automatically be extracted from that plugin if necessary.
+
+## Fixes in v10.0.1 (2021-11-19): 
+
+- Hotfix update to fix broken EPUB DRM removal due to a typo.
+
+## Fixes in v10.0.2 (2021-11-29):
+
+- Fix Kindle for Mac key retrieval (merged [apprenticeharper/DeDRM_tools#1936](https://github.com/apprenticeharper/DeDRM_tools/pull/1936) ), fixing #1. 
+- Fix Adobe key retrieval in case the username has been changed (merged [apprenticeharper/DeDRM_tools#1946](https://github.com/apprenticeharper/DeDRM_tools/pull/1946) ). This should fix the error "failed to decrypt user key key".
+- Fix small issue with elibri watermark removal.
+- Adobe key name will now contain account email.
+
+## Fixes in v10.0.3 (2022-07-13):
+
+- Fix issue where importing a key from Adobe Digital Editions would fail in Python2 (Calibre < 5) if there were non-ASCII characters in the username.
+- Add code to support importing multiple decryption keys from ADE.
+- Improve epubtest.py to also detect Kobo & Apple DRM.
+- ~Small updates to the LCP DRM error messages.~ (removed due to a DMCA request, see #18 ).
+- Merge ignobleepub into ineptepub so there's no duplicate code.
+- Support extracting the B&N / Nook key from the NOOK Microsoft Store application (based on [this script](https://github.com/noDRM/DeDRM_tools/discussions/9) by fesiwi).
+- Support extracting the B&N / Nook key from a data dump of the NOOK Android application.
+- Support adding an existing PassHash / B&N key base64 string without having to write it to a file first.
+- Support extracting PassHash keys from Adobe Digital Editions.
+- Fix a bug that might have stopped the eReader PDB DRM removal from working (untested, I don't have any PDB books)
+- Fix a bug where the watermark removal code wouldn't run for DRM-free files.
+- ineptpdf: Add code to plugin to support "Standard" (tested) and "Adobe.APS" (untested) encrypted PDFs using the ineptpdf implementation (PDF passwords can be entered in the plugin settings)
+- ineptpdf: Support for decrypting PDF with owner password instead of user password.
+- ineptpdf: Add function to return Filter name.
+- ineptpdf: Support for V=5, R=5 and R=6 PDF files, and for AES256-encrypted PDFs.
+- ineptpdf: Disable cross-reference streams in the output file. This may make PDFs slightly larger, but the current code for cross-reference streams seems to be buggy and sometimes creates corrupted PDFs.
+- Drop support for importing key data from the ancient, pre "DeDRM" Calibre plugins ("Ignoble Epub DeDRM", "eReader PDB 2 PML" and "K4MobiDeDRM"). These are from 2011, I doubt anyone still has these installed, I can't even find a working link for these to test them. If you still have encryption keys in one of these plugins, you will need to update to DeDRM v10.0.2 or older (to convert the keys) before updating to DeDRM v10.0.3 or newer.
+- Some Python3 bugfixes for Amazon books (merged #10 by ableeker).
+- Fix a bug where extracting an Adobe key from ADE on Linux through Wine did fail when using the OpenSSL backend (instead of PyCrypto). See #13 and #14 for details, thanks acaloiaro for the bugfix.
+- Fix IndexError when DeDRMing some Amazon eBooks.
+- Add support for books with the new ADE3.0+ DRM by merging #48 by a980e066a01. Thanks a lot! (Also fixes #96 on MacOS)
+- Remove OpenSSL support, now the plugin will always use the Python crypto libraries.
+- Obok: Fix issues with invalid UTF-8 characters by merging #26 by baby-bell.
+- ineptpdf: Fix broken V=3 key obfuscation algorithm. 
+- ineptpdf: (Hopefully) fix issues with some B&N PDF files.
+- Fix broken Amazon K4PC key retrieval (fixes #38)
+- Fix bug that corrupts output file for Print-Replica Amazon books (fixes #30).
+- Fix Nook Study key retrieval code (partially fixes #50).
+- Make the plugin work on Calibre 6 (Qt 6). (fixes #54 and #98) If you're running Calibre 6 and you notice any issues, please open a bug report.
+
+## Fixes in v10.0.9 (RC for v10.1.0, 2023-08-02):
+
+Note that versions v10.0.4(s), v10.0.5(s) and v10.0.6(s) were released by other people in various forks, so I have decided to make a larger version jump so there are no conflicting version numbers / different builds with the same version number. 
+
+This is v10.0.9, a release candidate for v10.1.0. I don't expect there to be major issues / bugs, but since a lot of code has changed in the last year I wanted to get some "extended testing" before this becomes v10.1.0. 
+
+- Fix a bug introduced with #48 that breaks DeDRM'ing on Calibre 4 (fixes #101).
+- Fix some more Calibre-6 bugs in the Obok plugin (should fix #114).
+- Fix a bug where invalid Adobe keys could cause the plugin to stop trying subsequent keys (partially fixes #109).
+- Fix DRM removal sometimes resetting the ZIP's internal "external_attr" value on Calibre 5 and newer.

+<h1>Managing Adobe PassHash Keys</h1>
+
+<p>Adobe PassHash is a variant of the Adobe DRM which is used by retailers like Barnes and Noble. Instead of using certificates and device-based authorization, this uses a username and password combination. In B&&Ns implementation however, the user never gets access to these credentials, just to the credential hash.</p>
+
+<h3>Changes at Barnes & Noble</h3>
+
+<p>Since 2014, Barnes & Noble is no longer using the default Adobe key generation algorithm, which used to be the full name as "username" and the full credit card number as "password" for the PassHash algorithm. 
+Instead, they started generating a random key on their server and send that to the reading application during login. This means that the old method to decrypt these books will no longer work. </p>
+
+<p>There used to be a way to use the Android app's API to simulate a login to the Barnes and Noble servers, but that API has been shut down a while ago, too, and so far nobody has reverse-engineered the new one.</p>
+
+<h3>Importing PassHash / B&N keys</h3>
+
+<p>On the right-hand side of the plugin’s customization dialog, you will see a button with an icon that looks like a green plus sign (+). Clicking this button will open a new dialog for entering the necessary data to generate a new key.</p>
+<p>Currently, the only known ways to access the key are the following:</p>
+<ul>
+	<li>B&N: The encryption key can be extracted from the NOOK reading application available in the Microsoft store, or from the old "Nook Study" application. To do that, click on the "Extract key from Nook Windows application" option.</li>
+	<li>B&N: The encryption key can also be extracted from a data backup of the NOOK Android application. To do that, you'll need to have a rooted Android device, a hacked / modified Nook APK file, or an Android emulator to be able to access the app data. If you have that, click on "Extract key from Nook Android application" and follow the instructions.</li>
+	<li>B&N: The NOOK Android application supports / accepts user-added CA certificates, so you can set up something like mitmproxy on your computer, tunnel your phone's traffic through that, and extract the ccHash key data from the server response. You can then add that hash through the "Base64-encoded PassHash key string" option.</li>
+	<li>If you already have a copy of the Nook ccHash key string (or, more general, the PassHash key string) in base64 encoding, you can either click on "Import existing keyfiles" if it's a file in b64 format, or you click on the "Base64-encoded PassHash key string" option while adding a new PassHash key.</li>
+	<li>For retailers other than B&N that are using the PassHash algorihm as intended, you can click on "Adobe PassHash username & password" to enter your credentials while adding a key. This is the same algorihm as the original credit card number based key generation for B&N.</li>
+	<li>Windows only: If you've successfully opened a PassHash-encrypted book in Adobe Digital Editions by entering username and password, you can dump the stored credentials from ADE.</li>
+</ul>
+
+
+<p>After you've selected a key retrieval method from the settings, the dialog may change and request some additional information depending on the key retrieval method. Enter that, then click the OK button to create and store the generated key. Or Cancel if you don’t want to create a key.</p>
+<p>New keys are checked against the current list of keys before being added, and duplicates are discarded.</p>
+
+<h3>Deleting Keys:</h3>
+
+<p>On the right-hand side of the plugin’s customization dialog, you will see a button with an icon that looks like a red "X". Clicking this button will delete the highlighted key in the list. You will be prompted once to be sure that’s what you truly mean to do. Once gone, it’s permanently gone.</p>
+
+<h3>Renaming Keys:</h3>
+
+<p>On the right-hand side of the plugin’s customization dialog, you will see a button with an icon that looks like a sheet of paper. Clicking this button will prompt you to enter a new name for the highlighted key in the list. Enter the new name for the encryption key and click the OK button to use the new name, or Cancel to revert to the old name..</p>
+
+<h3>Exporting Keys:</h3>
+
+<p>On the right-hand side of the plugin’s customization dialog, you will see a button with an icon that looks like a computer’s hard-drive. Use this button to export the highlighted key to a file (with a ‘.b64’ file name extension). Used for backup purposes or to migrate key data to other computers/calibre installations. The dialog will prompt you for a place to save the file.</p>
+
+<h3>Importing Existing Keyfiles:</h3>
+
+<p>At the bottom-left of the plugin’s customization dialog, you will see a button labeled "Import Existing Keyfiles". Use this button to import existing ‘.b64’ key files. Key files might come from being exported from this or older plugins, or may have been generated using the original i♥cabbages script, or you may have made it by following the instructions above.</p>
+
+<p>Once done creating/deleting/renaming/importing decryption keys, click Close to exit the customization dialogue. Your changes will only be saved permanently when you click OK in the main configuration dialog.</p>

+<h1>DeDRM Plugin <span class="version">(v10.0.9 / v10.1.0 RC1)</span></h1>
+
+<p>This plugin removes DRM from ebooks when they are imported into calibre. If you already have DRMed ebooks in your calibre library, you will need to remove them and import them again.</p>
+
+<p>It is a forked version created by NoDRM, based on the original plugin by Apprentice Alf and Apprentice Harper.</p>
+
+<h3>Installation</h3>
+<p>You have obviously managed to install the plugin, as otherwise you wouldn’t be reading this help file. However, you should also delete any older DRM removal plugins, as this DeDRM plugin replaces the five older plugins: Kindle and Mobipocket DeDRM (K4MobiDeDRM), Ignoble Epub DeDRM (ignobleepub), Inept Epub DeDRM (ineptepub), Inept PDF DeDRM (ineptepub) and eReader PDB 2 PML (eReaderPDB2PML).</p>
+
+<p>This plugin (in versions v10.0.0 and above) will automatically replace the older 7.X and below versions from Apprentice Alf and Apprentice Harper.</p>
+
+<h3>Configuration</h3>
+<p>On Windows and Mac, the keys for ebooks downloaded for Kindle for Mac/PC and Adobe Digital Editions are automatically generated. If all your DRMed ebooks can be opened and read in Kindle for Mac/PC and/or Adobe Digital Editions on the same computer on which you are running calibre, you do not need to do any configuration of this plugin. On Linux, keys for Kindle for PC and Adobe Digital Editions need to be generated separately (see the Linux section below).</p>
+
+<p>If you are using the <a href="https://www.mobileread.com/forums/showthread.php?t=341975">DeACSM / ACSM Input Plugin</a> for Calibre, the keys will also automatically be dumped for you.</p>
+
+<p>If you have other DRMed ebooks, you will need to enter extra configuration information. The buttons in this dialog will open individual configuration dialogs that will allow you to enter the needed information, depending on the type and source of your DRMed eBooks. Additional help on the information required is available in each of the the dialogs.</p>
+
+<p>If you have used previous versions of the various DeDRM plugins on this machine, you may find that some of the configuration dialogs already contain the information you entered through those previous plugins.</p>
+
+<p>When you have finished entering your configuration information, you <em>must</em> click the OK button to save it. If you click the Cancel button, all your changes in all the configuration dialogs will be lost.</p>
+
+<h3>Troubleshooting:</h3>
+
+<p>If you find that it’s not working for you , you can save a lot of time by trying to add the ebook to Calibre in debug mode. This will print out a lot of helpful info that can be copied into any online help requests.</p>
+
+<p>Open a command prompt (terminal window) and type "calibre-debug -g" (without the quotes). Calibre will launch, and you can can add the problem ebook the usual way. The debug info will be output to the original command prompt (terminal window). Copy the resulting output and paste it into the comment you make at my blog.</p>
+<p><span class="bold">Note:</span> The Mac version of Calibre doesn’t install the command line tools by default. If you go to the ‘Preferences’ page and click on the miscellaneous button, you’ll find the option to install the command line tools.</p>

+<h2>Linux Systems Only</h2>
+<h3>Generating decryption keys for Adobe Digital Editions and Kindle for PC</h3>
+<p>If you install Kindle for PC and/or Adobe Digital Editions in Wine, you will be able to download DRMed ebooks to them under Wine. To be able to remove the DRM, you will need to generate key files and add them in the plugin's customisation dialogs.</p>
+
+<p>To generate the key files you will need to install Python and PyCrypto under the same Wine setup as your Kindle for PC and/or Adobe Digital Editions installations. (Kindle for PC, Python and Pycrypto installation instructions in the ReadMe.)</p>
+
+<p>Once everything's installed under Wine, you'll need to run the adobekey.pyw script (for Adobe Digital Editions) and kindlekey.pyw (For Kindle for PC) using the python installation in your Wine system. The scripts can be found in Other_Tools/Key_Retrieval_Scripts.</p>
+
+<p>Each script will create a key file in the same folder as the script. Copy the key files to your Linux system and then load the key files using the Adobe Digital Editions ebooks dialog and the Kindle for Mac/PC ebooks dialog.</p>

+<h1>Managing Kindle for Android Keys</h1>
+
+<p>Amazon's Kindle for Android application uses an internal key equivalent to an eInk Kindle's serial number. Extracting that key is a little tricky, but worth it, as it then allows the DRM to be removed from any Kindle ebooks that have been downloaded to that Android device.</p>
+
+<p>Please note that it is not currently known whether the same applies to the Kindle application on the Kindle Fire and Fire HD.</p>
+
+<h3>Getting the Kindle for Android backup file</h3>
+
+<p>Obtain and install adb (Android Debug Bridge) on your computer. Details of how to do this are beyond the scope of this help file, but there are plenty of on-line guides.</p>
+<p>Enable developer mode on your Android device. Again, look for an on-line guide for your device.</p>
+<p>Once you have adb installed and your device in developer mode, connect your device to your computer with a USB cable and then open up a command line (Terminal on Mac OS X and cmd.exe on Windows) and enter "adb backup com.amazon.kindle" (without the quotation marks!) and press return. A file "backup.ab" should be created in your home directory.
+
+<h3>Adding a Kindle for Android Key</h3>
+
+<p>On the right-hand side of the plugin’s customization dialog, you will see a button with an icon that looks like a green plus sign (+).  Clicking this button will open a new dialog with two main controls.
+<ul>
+<li><span class="bold">Choose backup file:</span> click this button and you will be prompted to find the backup.ab file you created earlier. Once selected the file will be processed to extract the decryption key, and if successful the file name will be displayed to the right of the button.</li>
+<li><span class="bold">Unique Key Name:</span> this is a unique name you choose to help you identify the key. This name will show in the list of Kindle for Android keys. Enter a name that will help you remember which device this key came from.</li>
+</ul>
+
+<p>Click the OK button to store the Kindle for Android key for the current list of Kindle for Android keys. Or click Cancel if you don’t want to store the key.</p>
+<p>New keys are checked against the current list of keys before being added, and duplicates are discarded.</p>
+
+<h3>Deleting Keys:</h3>
+
+<p>On the right-hand side of the plugin’s customization dialog, you will see a button with an icon that looks like a red "X". Clicking this button will delete the highlighted key in the list. You will be prompted once to be sure that’s what you truly mean to do. Once gone, it’s permanently gone.</p>
+
+<h3>Renaming Keys:</h3>
+
+<p>On the right-hand side of the plugin’s customization dialog, you will see a button with an icon that looks like a sheet of paper. Clicking this button will prompt you to enter a new name for the highlighted key in the list. Enter the new name for the key and click the OK button to use the new name, or Cancel to revert to the old name.</p>
+
+<h3>Exporting Keys:</h3>
+
+<p>On the right-hand side of the plugin’s customization dialog, you will see a button with an icon that looks like a computer’s hard-drive. Use this button to export the highlighted key to a file (with a ‘.k4a' file name extension). Used for backup purposes or to migrate key data to other computers/calibre installations. The dialog will prompt you for a place to save the file.</p>
+
+<h3>Importing Existing Keyfiles:</h3>
+
+<p>At the bottom-left of the plugin’s customization dialog, you will see a button labeled "Import Existing Keyfiles". Use this button to import any ‘.k4a’ file you obtained by using the androidkindlekey.py script manually, or by exporting from another copy of calibre.</p>

+<h1>Managing Readium LCP passphrases</h1>
+
+<p>Readium LCP is a relatively new eBook DRM. It's also known under the names "CARE DRM" or "TEA DRM". It does not rely on any accounts or key data that's difficult to acquire. All you need to open (or decrypt) LCP eBooks is the account passphrase given to you by the eBook provider - the very same passphrase you'd have to enter into your eBook reader device (once) to read LCP-encrypted books.</p>
+
+<p>This plugin no longer supports removing the Readium LCP DRM due to a DMCA takedown request issued by Readium. Please read the <a href="https://github.com/github/dmca/blob/master/2022/01/2022-01-04-readium.md">takedown notice</a> or <a href="https://github.com/noDRM/DeDRM_tools/issues/18">this bug report</a> for more information.</p>
+
+<h3>Entering an LCP passphrase:</h3>
+
+<p>On the right-hand side of the plugin’s customization dialog, you will see a button with an icon that looks like a green plus sign (+). Clicking this button will open a new dialog for entering a new passphrase.</p>
+
+<p>Just enter your passphrase as provided with the book, then click the OK button to save the passphrase. </p>
+
+<p>Usually, passphrases are identical for all books bought with the same account. So if you buy multiple LCP-protected eBooks, they'll usually all have the same passphrase if they've all been bought at the same store with the same account. </p>
+
+<h3>Deleting an LCP passphrase:</h3>
+
+<p>On the right-hand side of the plugin’s customization dialog, you will see a button with an icon that looks like a red "X".

+#
+# Changelog
+#
+#  Based on ereader2html version 0.08 plus some later small fixes
+#
+#  0.01 - Initial version
+#  0.02 - Support more eReader files. Support bold text and links. Fix PML decoder parsing bug.
+#  0.03 - Fix incorrect variable usage at one place.
+#  0.03b - enhancement by DeBockle (version 259 support)
+# Custom version 0.03 - no change to eReader support, only usability changes
+#   - start of pep-8 indentation (spaces not tab), fix trailing blanks
+#   - version variable, only one place to change
+#   - added main routine, now callable as a library/module,
+#     means tools can add optional support for ereader2html
+#   - outdir is no longer a mandatory parameter (defaults based on input name if missing)
+#   - time taken output to stdout
+#   - Psyco support - reduces runtime by a factor of (over) 3!
+#     E.g. (~600Kb file) 90 secs down to 24 secs
+#       - newstyle classes
+#       - changed map call to list comprehension
+#         may not work with python 2.3
+#         without Psyco this reduces runtime to 90%
+#         E.g. 90 secs down to 77 secs
+#         Psyco with map calls takes longer, do not run with map in Psyco JIT!
+#       - izip calls used instead of zip (if available), further reduction
+#         in run time (factor of 4.5).
+#         E.g. (~600Kb file) 90 secs down to 20 secs
+#   - Python 2.6+ support, avoid DeprecationWarning with sha/sha1
+#  0.04 - Footnote support, PML output, correct charset in html, support more PML tags
+#   - Feature change, dump out PML file
+#   - Added supprt for footnote tags. NOTE footnote ids appear to be bad (not usable)
+#       in some pdb files :-( due to the same id being used multiple times
+#   - Added correct charset encoding (pml is based on cp1252)
+#   - Added logging support.
+#  0.05 - Improved type 272 support for sidebars, links, chapters, metainfo, etc
+#  0.06 - Merge of 0.04 and 0.05. Improved HTML output
+#         Placed images in subfolder, so that it's possible to just
+#         drop the book.pml file onto DropBook to make an unencrypted
+#         copy of the eReader file.
+#         Using that with Calibre works a lot better than the HTML
+#         conversion in this code.
+#  0.07 - Further Improved type 272 support for sidebars with all earlier fixes
+#  0.08 - fixed typos, removed extraneous things
+#  0.09 - fixed typos in first_pages to first_page to again support older formats
+#  0.10 - minor cleanups
+#  0.11 - fixups for using correct xml for footnotes and sidebars for use with Dropbook
+#  0.12 - Fix added to prevent lowercasing of image names when the pml code itself uses a different case in the link name.
+#  0.13 - change to unbuffered stdout for use with gui front ends
+#  0.14 - contributed enhancement to support --make-pmlz switch
+#  0.15 - enabled high-ascii to pml character encoding. DropBook now works on Mac.
+#  0.16 - convert to use openssl DES (very very fast) or pure python DES if openssl's libcrypto is not available
+#  0.17 - added support for pycrypto's DES as well
+#  0.18 - on Windows try PyCrypto first and OpenSSL next
+#  0.19 - Modify the interface to allow use of import
+#  0.20 - modify to allow use inside new interface for calibre plugins
+#  0.21 - Support eReader (drm) version 11.
+#       - Don't reject dictionary format.
+#       - Ignore sidebars for dictionaries (different format?)
+#  0.22 - Unicode and plugin support, different image folders for PMLZ and source
+#  0.23 - moved unicode_argv call inside main for Windows DeDRM compatibility
+#  1.00 - Added Python 3 compatibility for calibre 5.0
+#  1.01 - Bugfixes for standalone version.
+#  1.02 - Remove OpenSSL support; only use PyCryptodome

+#
+# Changelog
+#  0.01 - Initial version
+#  0.02 - Huffdic compressed books were not properly decrypted
+#  0.03 - Wasn't checking MOBI header length
+#  0.04 - Wasn't sanity checking size of data record
+#  0.05 - It seems that the extra data flags take two bytes not four
+#  0.06 - And that low bit does mean something after all :-)
+#  0.07 - The extra data flags aren't present in MOBI header < 0xE8 in size
+#  0.08 - ...and also not in Mobi header version < 6
+#  0.09 - ...but they are there with Mobi header version 6, header size 0xE4!
+#  0.10 - Outputs unencrypted files as-is, so that when run as a Calibre
+#         import filter it works when importing unencrypted files.
+#         Also now handles encrypted files that don't need a specific PID.
+#  0.11 - use autoflushed stdout and proper return values
+#  0.12 - Fix for problems with metadata import as Calibre plugin, report errors
+#  0.13 - Formatting fixes: retabbed file, removed trailing whitespace
+#         and extra blank lines, converted CR/LF pairs at ends of each line,
+#         and other cosmetic fixes.
+#  0.14 - Working out when the extra data flags are present has been problematic
+#         Versions 7 through 9 have tried to tweak the conditions, but have been
+#         only partially successful. Closer examination of lots of sample
+#         files reveals that a confusion has arisen because trailing data entries
+#         are not encrypted, but it turns out that the multibyte entries
+#         in utf8 file are encrypted. (Although neither kind gets compressed.)
+#         This knowledge leads to a simplification of the test for the
+#         trailing data byte flags - version 5 and higher AND header size >= 0xE4.
+#  0.15 - Now outputs 'heartbeat', and is also quicker for long files.
+#  0.16 - And reverts to 'done' not 'done.' at the end for unswindle compatibility.
+#  0.17 - added modifications to support its use as an imported python module
+#         both inside calibre and also in other places (ie K4DeDRM tools)
+#  0.17a- disabled the standalone plugin feature since a plugin can not import
+#         a plugin
+#  0.18 - It seems that multibyte entries aren't encrypted in a v7 file...
+#         Removed the disabled Calibre plug-in code
+#         Permit use of 8-digit PIDs
+#  0.19 - It seems that multibyte entries aren't encrypted in a v6 file either.
+#  0.20 - Correction: It seems that multibyte entries are encrypted in a v6 file.
+#  0.21 - Added support for multiple pids
+#  0.22 - revised structure to hold MobiBook as a class to allow an extended interface
+#  0.23 - fixed problem with older files with no EXTH section
+#  0.24 - add support for type 1 encryption and 'TEXtREAd' books as well
+#  0.25 - Fixed support for 'BOOKMOBI' type 1 encryption
+#  0.26 - Now enables Text-To-Speech flag and sets clipping limit to 100%
+#  0.27 - Correct pid metadata token generation to match that used by skindle (Thank You Bart!)
+#  0.28 - slight additional changes to metadata token generation (None -> '')
+#  0.29 - It seems that the ideas about when multibyte trailing characters were
+#         included in the encryption were wrong. They are for DOC compressed
+#         files, but they are not for HUFF/CDIC compress files!
+#  0.30 - Modified interface slightly to work better with new calibre plugin style
+#  0.31 - The multibyte encrytion info is true for version 7 files too.
+#  0.32 - Added support for "Print Replica" Kindle ebooks
+#  0.33 - Performance improvements for large files (concatenation)
+#  0.34 - Performance improvements in decryption (libalfcrypto)
+#  0.35 - add interface to get mobi_version
+#  0.36 - fixed problem with TEXtREAd and getBookTitle interface
+#  0.37 - Fixed double announcement for stand-alone operation
+#  0.38 - Unicode used wherever possible, cope with absent alfcrypto
+#  0.39 - Fixed problem with TEXtREAd and getBookType interface
+#  0.40 - moved unicode_argv call inside main for Windows DeDRM compatibility
+#  0.41 - Fixed potential unicode problem in command line calls
+#  0.42 - Added GPL v3 licence. updated/removed some print statements
+#  1.0  - Python 3 compatibility for calibre 5.0
+#  1.1  - Speed Python PC1 implementation up a little bit

+DeDRM_plugin.zip
+================
+
+This plugin will remove the DRM from:
+
+ - Kindle ebooks (files from Kindle for Mac/PC and eInk Kindles).
+ - Adobe Digital Editions ePubs (including Kobo and Google ePubs downloaded to ADE)
+ - Adobe Digital Editions PDFs
+
+For limitations and work-arounds, see the FAQ at https://github.com/noDRM/DeDRM_tools/blob/master/FAQs.md (or the FAQ in Apprentice Harper's original repository at https://github.com/apprenticeharper/DeDRM_tools/blob/master/FAQs.md)
+
+
+Installation
+------------
+Open calibre's Preferences dialog.  Click on the "Plugins" button.  Next, click on the button, "Load plugin from file".  Navigate to the unzipped DeDRM_tools folder, find the file "DeDRM_plugin.zip".  Click to select the file and select "Open".  Click "Yes" in the "Are you sure?" dialog box. Click the "OK" button in the "Success" dialog box.
+
+
+Customization
+-------------
+For Kindle ebooks from an E-Ink based Kindle (e.g. Voyage), or books downloaded from the Amazon web site 'for transfer via USB' to an E-Ink base Kindle, you must enter the Kindle's serial number in the customisation dialog.
+
+When you have finished entering your configuration information, you must click the OK button to save it. If you click the Cancel button, all your changes in all the configuration dialogs will be lost.
+
+
+Troubleshooting
+---------------
+If you find that the DeDRM plugin is not working for you (imported ebooks still have DRM - that is, they won't convert or open in the calibre ebook viewer), you should make a log of the import process by deleting the DRMed ebook from calibre and then adding the ebook to calibre when it's running in debug mode. This will generate a lot of helpful debugging info that can be copied into any online help requests. Here's how to do it:
+
+ - Remove the DRMed book from calibre.
+ - Click the Preferences drop-down menu and choose 'Restart in debug mode'.
+ - Once calibre has re-started, import the problem ebook.
+ - Now close calibre.
+
+A log will appear that you can copy and paste into a GitHub issue report at https://github.com/noDRM/DeDRM_tools/issues. Please also include information about the eBook file.
+
+If you're using Apprentice Harper's original version, you can also comment at Apprentice Alf's blog, http://apprenticealf.wordpress.com/ or open an issue at Apprentice Harper's repository, https://github.com/apprenticeharper/DeDRM_tools/issues.

+# Overview
+## What's this repository all about?
+Providing free open source tools to remove DRM from your ebooks.
+
+## What's DRM?
+DRM ("Digital Rights Management") is a way of using encryption to tie the books you've bought to a specific device or to a particular piece of software.
+
+## Why would I want to remove DRM from my ebooks?
+When your ebooks have DRM you are unable to convert the ebook from one format to another (e.g. Kindle KF8 to Kobo ePub), so you are restricted in the range of ebook stores you can use. DRM also allows publishers to restrict what you can do with the ebook you've bought, e.g. preventing the use of text-to-speech software. Longer term, you can never be sure that you'll be able to come back and re-read your ebooks if they have DRM, even if you save back-up copies.
+
+## So how can I remove DRM from my ebooks?
+Just download and use these tools, that's all! Uh, almost. There are a few, uh, provisos, a couple of quid pro quos. 
+
+* The tools don't work on all ebooks. For example, they don't work on any ebooks from Apple's iBooks store.
+* You must own the ebook - the tools won't work on library ebooks or rented ebooks or books from a friend.
+* You must not use these tools to give your ebooks to a hundred of your closest friends. Or to a million strangers. Authors need to sell books to be able to write more books. Don't be mean to the authors.
+
+### Recent Changes to Kindle for PC/Kindle for Mac
+Starting with version 1.19, Kindle for PC/Mac uses Amazon's new KFX format which isn't quite as good a source for conversion to ePub as the older KF8 (& MOBI) formats. There are two options to get the older formats. Either stick with version 1.17 or earlier, or modify the executable by changing a file name (PC) or disabling a component of the application (Mac). 
+
+Version 1.17 of Kindle is no longer available directly from Amazon, so you will need to search for the proper file name and find it on a third party site. The name is `KindleForPC-installer-1.17.44170.exe` for PC and `KindleForMac-44182.dmg` for Mac.  (Note that this is a 32-bit application on the Mac, so will not work on Catalina and newer versions of macOS.)
+Verify the one of the following cryptographic hash values, using software of your choice, before installing the downloaded file in order to avoid viruses. If the hash does not match, delete the downloaded file and try again from another site.
+
+#### Kindle for PC `KindleForPC-installer-1.17.44170.exe`:
+* MD-5: 53F793B562F4823721AA47D7DE099869
+* SHA-1: 73C404D719F0DD8D4AE1C2C96612B095D6C86255
+* SHA-256: 14E0F0053F1276C0C7C446892DC170344F707FBFE99B6951762C120144163200
+
+#### Kindle for Mac `KindleForMac-44182.dmg`:
+* MD-5: E7E36D5369E1F3CF1D28E5D9115DF15F
+* SHA-1: 7AB9A86B954CB23D622BD79E3257F8E2182D791C
+* SHA-256: 28DC21246A9C7CDEDD2D6F0F4082E6BF7EF9DB9CE9D485548E8A9E1D19EAE2AC
+
+You will need to go to the preferences and uncheck the auto update checkbox. Then download and install 1.17 over the top of the newer installation. You'll also need to delete the KFX folders from your My Kindle Content folder. You may also need to take further action to prevent an auto update. The simplest way is to find the 'updates' folder and replace it with a file. See [this thread] (http://www.mobileread.com/forums/showthread.php?t=283371) at MobileRead for a Script to do this on a PC. On a Mac you can find the folder at ~/Library/Application Support/Kindle/. Make the 'updates' folder read-only, or delete it and save a blank text file called 'updates' in its place.
+
+Another possible solution is to use 1.19 or later, but disable KFX by renaming or disabling a necessary component of the application. This may or may not work on versions after 1.25. In a command window, enter the following commands when Kindle for PC/Mac is not running:
+
+#### Windows
+`ren %localappdata%\Amazon\Kindle\application\renderer-test.exe renderer-test.xxx`
+
+PC Note: The renderer-test program may be in a different location in some Kindle for PC installations. If the rename command fails look in other folders, such as `C:\Program Files\Amazon\Kindle`.
+
+#### Macintosh
+`chmod -x /Applications/Kindle.app/Contents/MacOS/renderer-test`
+
+Mac Note: If the chmod command fails with a permission error try again using `sudo` before `chmod` - `sudo chmod` [...]. This only works on Kindle for Mac 1.19 thru 1.31, it does NOT work with 1.32 or newer.
+
+After restarting the Kindle program any books previously downloaded in KFX format will no longer open. You will need to remove them from your device and re-download them. All future downloads will use the older Kindle formats instead of KFX although they will continue to be placed in one individual subdirectory per book. Note that books should be downloaded by right-click and 'Download', not by just opening the book. Recent (1.25+) versions of Kindle for Mac/PC may convert KF8 files to a new format that is not supported by these tools when the book is opened for reading.

+#### Decrypting KFX
+Thanks to work by several people, the tools can now decrypt KFX format ebooks from Kindle for Mac/PC. In addition to the DeDRM plugin, calibre users will also need to install jhowell's KFX Input plugin which is available through the standard plugin menu in calibre, or directly from [his plugin thread](https://www.mobileread.com/forums/showthread.php?t=291290) on Mobileread. 
+
+It's quite possible that Amazon will update their KFX DeDRM to prevent DRM removal from KFX books again. So Remove DRM as soon as possible!
+
+#### Thanks
+Thanks to jhowell for his investigations into KFX format and the KFX Input plugin. Some of these instructions are from [his thread on the subject](https://www.mobileread.com/forums/showthread.php?t=283371) at MobileRead.
+
+## Where can I get the latest version of these free DRM removal tools?
+Right here at github. Just go to the [releases page](https://github.com/noDRM/DeDRM_tools/releases) and download the latest zip archive of the tools, named `DeDRM\_tools\_X.X.X.zip`, where X.X.X is the version number. You do not need to download the source code archive. This will get you the forked version by noDRM. If you want to download the original version by Apprentice Harper, go to [this page](https://github.com/apprenticeharper/DeDRM_tools/releases) instead. 
+
+## I've downloaded the tools archive. Now what?
+First, unzip the archive. You should now have a DeDRM folder containing several files, including a `ReadMe_Overview.txt` file. Please read the `ReadMe_Overview.txt` file! That will explain what the files are, and you'll be able to work out which of the tools you need.
+
+## That's a big complicated ReadMe file! Isn't there a quick guide?
+Install calibre. Install the DeDRM\_plugin in calibre. Install the Obok\_plugin in calibre. Restart calibre. In the DeDRM_plugin customisation dialog add in any E-Ink Kindle serial numbers. Remember that the plugin only tries to remove DRM when ebooks are imported.
+
+# Installing the Tools
+## The calibre plugin
+### I am trying to install the calibre plugin, but calibre says "ERROR: Unhandled exception: InvalidPlugin: The plugin in '[path]DeDRM\_tools\_X.X.X.zip' is invalid. It does not contain a top-level \_\_init\_\_.py file"
+You are trying to add the tools archive (e.g. `DeDRM_tools_10.0.2.zip`) instead of the plugin. The tools archive is not the plugin. It is a collection of DRM removal tools which includes the plugin. You must unzip the archive, and install the calibre plugin `DeDRM_plugin.zip` from inside the unzipped archive.
+
+### I’ve unzipped the tools archive, but I can’t find the calibre plugin when I try to add them to calibre. I use Windows.
+You should select the zip file that is in the `DeDRM_calibre_plugin` folder, not any files inside the plugin’s zip archive. Make sure you are selecting from the folder that you created when you unzipped the tools archive and not selecting a file inside the still-zipped tools archive.
+
+(The problem is that Windows will allow apps to browse inside zip archives without needing to unzip them first. If there are zip archives inside the main zip archives, Windows will show them as unzipped as well. So what happens is people will unzip the `DeDRM_tools_X.X.X.zip` to a folder, but when using calibre they will actually navigate to the still zipped file by mistake and cannot tell they have done so because they do not have file extensions showing. So to the unwary Windows user, it appears that the zip archive was unzipped and that everything inside it was unzipped as well so there is no way to install the plugins.
+
+We strongly recommend renaming the `DeDRM_tools_X.X.X.zip` archive (after extracting its contents) to `DeDRM_tools_X.X.X_archive.zip`. If you do that, you are less likely to navigate to the wrong location from inside calibre.)
+
+# Using the Tools
+## I can’t get the tools to work on my rented or library ebooks.
+The tools are not designed to remove DRM from rented or library ebooks.
+
+## I've unzipped the tools, but what are all the different files, and how do I use them?
+Read the `ReadMe_Overview.txt` file and then the ReadMe files for the tools you're interested in. That's what they're for.
+
+## I have installed the calibre plugin, but my books still have DRM. When I try to view or convert my books, calibre says they have DRM.
+DRM only gets removed when an ebook is imported into calibre. Also, if the book is already in calibre, by default calibre will discard the newly imported file. You can change this in calibre's Adding books preferences page (Automerge..../Overwrite....), so that newly imported files overwrite existing ebook formats. Then just re-import your books and the DRM-free versions will overwrite the DRMed versions while retaining your books' metadata.
+
+## I have installed the calibre plugin, but I don’t know where my ebooks are stored.
+Your ebooks are stored on your computer or on your ebook reader. You need to find them to be able to remove the DRM. If they are on your reader, you should be able to locate them easily. On your computer it’s not so obvious. Here are the default locations.
+
+### Macintosh
+Navigating from your home folder,
+
+Kindle for Mac ebooks are in either `Library/Application Support/Kindle/My Kindle Content` or `Documents/My Kindle Content` or `Library/Containers/com.amazon.Kindle/Data/Library/Application Support/Kindle/My Kindle Content`, depending on your version of Kindle for Mac.
+
+Adobe Digital Editions ebooks are in `Documents/Digital Editions`
+
+### Windows
+Navigating from your `Documents` folder (`My Documents` folder, pre-Windows 7)
+
+Kindle for PC ebooks are in `My Kindle Content`
+
+Adobe Digital Editions ebooks are in `My Digital Editions`
+
+
+## I have installed the calibre plugin, and the book is not already in calibre, but the DRM does not get removed.
+You must use the exact file that is used by your ebook reading software or hardware. See the previous question on where to find your ebook files. Do not use an old copy you have that you can no longer read.
+If you cannot read the ebook on your current device or installed software, the tools will certainly not be able to remove the DRM. Download a fresh copy that does work with your current device or installed software.
+
+## I have installed the calibre plugin, and the book is not already in calibre, but the DRM does not get removed. It is a Kindle book.
+If you are on Windows 8 and using the Windows 8 AppStore Kindle app, you must download and install the Kindle for PC application directly from the Amazon website. The tools do not work with the Windows 8 AppStore Kindle app.
+
+If this book is from an eInk Kindle (e.g. Paperwhite), you must enter the serial number into the configuration dialog. The serial number is sixteen characters long, and is case-sensitive.
+
+If this book is from Kindle for Mac or Kindle for PC, you must have the Kindle Software installed on the same computer and user account as your copy of calibre.
+
+If the book is from Kindle for PC or Kindle for Mac and you think you are doing everything right, and you are getting this message, it is possible that the files containing the encryption key aren’t quite in the format the tools expect. To try to fix this:
+
+1. Deregister Kindle for PC/Mac from your Amazon account.
+1. Uninstall Kindle for PC/Mac
+1. Delete the Kindle for PC/Mac preferences
+    * PC: Delete the directory `[home folder]\AppData\Local\Amazon` (it might be hidden) and `[home folder]\My Documents\My Kindle Content`
+    * Mac: Delete the directory `[home folder]/Library/Application Support/Kindle/` and/or `[home folder]/Library/Containers/com.amazon.Kindle/Data/Library/Application Support/Kindle/` (one or both may be present and should be deleted)
+1. Reinstall Kindle for PC/Mac version 1.17 or earlier (see above for download links).
+1. Re-register Kindle for PC/Mac with your Amazon account
+1. Download the ebook again. Do not use the files you have downloaded previously.
+
+## Some of my books had their DRM removed, but some still say that they have DRM and will not convert.
+There are several possible reasons why only some books get their DRM removed.
+* You still don’t have the DRM removal tools working correctly, but some of your books didn’t have DRM in the first place.
+
+If you are still having problems with particular books, you will need to create a log of the DRM removal attempt for one of the problem books. If you're using NoDRM's fork, open [a new issue](https://github.com/noDRM/DeDRM_tools/issues) in the GitHub repo. If you're using Apprentice Harper's version, post that logfile in a new issue at [Apprentice Harper's github repository](https://github.com/apprenticeharper/DeDRM_tools/issues).
+
+## My Kindle book has imported and the DRM has been removed, but all the pictures are gone.
+Most likely, this is a book downloaded from Amazon directly to an eInk Kindle (e.g. Paperwhite). Unfortunately, the pictures are probably in a `.azw6` file that the tools don't understand. You must download the book manually from Amazon's web site "For transfer via USB" to your Kindle. When you download the eBook in this manner, Amazon will package the pictures in the with text in a single file that the tools will be able to import successfully.
+
+## My Kindle book has imported, but it's showing up as an AZW4 format. Conversions take a long time and/or are very poor.
+You have found a Print Replica Kindle ebook. This is a PDF in a Kindle wrapper. Now the DRM has been removed, you can extract the PDF from the wrapper using the KindleUnpack plugin. Conversion of PDFs rarely gives good results.
+
+## Do the tools work on books from Kobo?
+If you use the Kobo desktop application for Mac or PC, install the Obok plugin. This will import and remove the DRM from your Kobo books, and is the easiest method for Kobo ebooks.
+
+## I cannot solve my problem with the DeDRM plugin, and now I need to ‘post a log’. How do I do that?
+Remove the DRMed book from calibre. Click the Preferences drop-down menu and choose 'Restart in debug mode'. Once calibre has re-started, import the problem ebook. Now close calibre. A log will appear that you can copy and paste into [a new issue](https://github.com/noDRM/DeDRM_tools/issues) in NoDRM’s GitHub repo. If you're using Apprentice Harper’s version, post that logfile in a new issue at [Apprentice Harper's GitHub repository](https://github.com/apprenticeharper/DeDRM_tools/issues).
+
+## Is there a way to use the DeDRM plugin for Calibre from the command line?
+See the [Calibre command line interface (CLI) instructions](CALIBRE_CLI_INSTRUCTIONS.md).
+
+## The plugin displays a "MemoryError" in its log file during DRM removal. 
+A "MemoryError" usually occurs when you're using the 32-bit version of Calibre (which is limited in the amount of useable RAM). If you have a 64-bit installation of your operating system (on Windows, press Windows+Break, then make sure it says "64-bit Operating System" under "System type"), try downloading the 64-bit version of Calibre instead of the 32-bit version. 
+
+If the error still occurs, even with the 64-bit version, please open a bug report.
+
+# General Questions
+
+## Once the DRM has been removed, is there any trace of my personal identity left in the ebook?
+That question cannot be answered for sure. While it is easy to check if a book has DRM or not, it is very difficult to verify if all (traces of) personal information have been removed from a book. The tools attempt to remove watermarks when they are detected (optionally, there's an option in the plugin settings to enable that), but that will not be the case for all watermarks. 
+
+## Why do some of my Kindle ebooks import as HTMLZ format in calibre?
+Most Amazon Kindle ebooks are Mobipocket format ebooks, or the new KF8 format. However, some are in a format known as Topaz. The Topaz format is only used by Amazon. A Topaz ebook is a collections of glyphs and their positions on each page tagged with some additional information from that page including OCRed text (Optical Character Recognition generated Text) to allow searching, and some additional layout information. Each page of a Topaz ebook is effectively a description of an image of that page. To convert a Topaz ebook to another format is not easy as there is not a one-to-one mapping between glyphs and characters/fonts. To account for this, two different formats are generated by the DRM removal software. The first is an html description built from the OCRtext and images stored in the Topaz file (HTMLZ). This format is easily reflowed but may suffer from typical OCRtext errors including typos, garbled text, missing italics, missing bolds, etc. The second format uses the glyph and position information to create an accurate scalable vector graphics (SVG) image of each page of the book that can be viewed in web browsers that support svg images (Safari, Firefox 4 or later, etc). Additional conversion software can be used to convert these SVG images to an image only PDF file. The DeDRM calibre plugin only imports the HTMLZ versions of the Topaz ebook. The html version can be manually cleaned up and spell checked and then converted using Sigil/calibre to epubs, mobi ebooks, and etc.
+
+## Are the tools open source? How can I be sure they are safe and not a trojan horse?
+All the DRM removal tools hosted here are almost entirely written in Python. So they are inherently open source, and open to inspection by everyone who downloads them.
+
+There are some optional shared libraries (`*.dll`, `*.dylib`, and `*.so`) included for performance. The source for any compiled pieces are provided within `alfcrypto_src.zip`. If this is a concern either delete the binary files (there's fallback code in the plugin that allows it to work without these, it will just be slower) or manually rebuild them from source.
+
+## What ebooks do these tools work on?
+The Calibre plugin removes DRM from PDF, ePub, kePub (Kobo), eReader, Kindle (Mobipocket, KF8, Print Replica and Topaz) format ebooks using Adobe Adept, Barnes & Noble, Amazon, Kobo and eReader DRM schemes. It used to remove Readium LCP DRM from ePub or PDF files in the past, but that functionality had to be removed due to a [DMCA takedown request](https://github.com/noDRM/DeDRM_tools/issues/18).
+
+Note these tools do NOT ‘crack’ the DRM. They simply allow the book’s owner to use the encryption key information already stored someplace on their computer or device to decrypt the ebook in the same manner the official ebook reading software uses.
+
+## Why don’t the tools work with Kindle Fire ebooks?
+Because no-one's found out how to remove the DRM from ebooks from Kindle Fire devices yet. The workaround is to install Kindle for PC or Kindle for Mac and use books from there instead.
+
+## Why don't the tools work with Kindle for iOS ebooks?
+Amazon changed the way the key was generated for Kindle for iOS books, and the tools can no longer find the key. The workaround is to install Kindle for PC or Kindle for Mac and use books from there instead.
+
+## Why don't the tools work with Kindle for Android ebooks?
+Amazon turned off backup for Kindle for Android, so the tools can no longer find the key. The workaround is to install Kindle for PC or Kindle for Mac and use books from there instead.
+
+## Why don't the tools work on books from the Apple iBooks Store?
+Apple regularly change the details of their DRM and so the tools in the main tools archive will not work with these ebooks. Apple’s Fairplay DRM scheme can be removed using Requiem if the appropriate version of iTunes can still be installed and used. See the post Apple and ebooks: iBookstore DRM and how to remove it at Apprentice Alf's blog for more details.
+
+## Why don't the tools work with LCP-encrypted ebooks? / Error message about a "DMCA takedown"
+Support for LCP DRM removal was included in the past, but Readium (the company who developed that particular DRM) has decided to [open a DMCA takedown request](https://github.com/github/dmca/blob/master/2022/01/2022-01-04-readium.md) in January 2022. This means that for legal reasons, this GitHub repository no longer contains the code needed to remove DRM from LCP-encrypted books. For more information please read [this bug report](https://github.com/noDRM/DeDRM_tools/issues/18). 
+
+## I’ve got the tools archive and I’ve read all the FAQs but I still can’t install the tools and/or the DRM removal doesn’t work
+* Read the `ReadMe_Overview.txt` file in the top level of the tools archive
+* Read the ReadMe file for the tool you want to use.
+* If you still can’t remove the DRM, create a new [GitHub issue](https://github.com/noDRM/DeDRM_tools/issues). If you are using Apprentice Harper's original version and not this fork, you can also create a new issue at Apprentice Harper's github repository. If you do report an issue in any of the GitHub repositories, please report the error as precisely as you can. Include what platform you use, what tool you have tried, what errors you get, and what versions you are using. If the problem happens when running one of the tools, post a log (see previous questions on how to do this).
+
+## Who wrote these scripts?
+The authors tend to identify themselves only by pseudonyms:
+* The Adobe Adept and Barnes & Noble scripts were created by i♥cabbages
+* The Adobe Adept support for ADE3.0+ DRM was added by a980e066a01
+* ~The Readium LCP support for this plugin was created by NoDRM~ (removed due to a DMCA takedown, see [#18](https://github.com/noDRM/DeDRM_tools/issues/18) )
+* The Amazon Mobipocket and eReader scripts were created by The Dark Reverser
+* The Amazon K4PC DRM/format was further decoded by Bart Simpson aka Skindle
+* The Amazon K4 Mobi tool was created by by some_updates, mdlnx and others
+* The Amazon Topaz DRM removal script was created by CMBDTC
+* The Amazon Topaz format conversion was created by some_updates, clarknova, and Bart Simpson
+* The DeDRM all-in-one calibre plugin was created by Apprentice Alf
+* The support for .kinf2018 key files  and KFX 2&3 was by Apprentice Sakuya
+* The Scuolabooks tool was created by Hex
+* The Microsoft code was created by drs
+* The Apple DRM removal tool was created by Brahms
+
+Since the original versions of the scripts and programs were released, various people have helped to maintain and improve them.

-#  0.09 - ...but they are there with Mobi header version 6, header size 0xE4!
-#  0.10 - Outputs unencrypted files as-is, so that when run as a Calibre
-#         import filter it works when importing unencrypted files.
-#         Also now handles encrypted files that don't need a specific PID.

-  database files on the desktop in pure Python without requiring
-  pilot-link (hence, it may be useful for import/export utilities),
-  and two, it caches the contents of the file in memory so it can

-How to get Drag&Drop decryption of DRM-encumbered Mobipocket eBook files.
-
-You'll need the MobiDeDRM.py python script, as well as an installed version 2.4 or later of python. If you have Mac OS X Leopard (10.5) you already have a suitable version of python installed as part of Leopard.
-
-Control-click the script and select "Show Package Contents" from the contextual menu. Copy the python script, which must be called "MobiDeDRM.py" into the Resources folder inside the Contents folder. (NB not into the Scripts folder - that's where the Applescript part is stored.)
-
-Close the package, and you now have a drag&drop Mobipocket unlocker.
-
-You can use the AppleScript ScriptEditor application to put your Mobipocket code into the script to save you having to enter it in the dialog all the time.

-#!/usr/bin/python

-# This is a python script. You need a Python interpreter to run it.
-# For example, ActiveState Python, which exists for windows.
-#
-# It can run standalone to convert files, or it can be installed as a
-# plugin for Calibre (http://calibre-ebook.com/about) so that
-# importing files with DRM 'Just Works'.
-#
-# To create a Calibre plugin, rename this file so that the filename
-# ends in '_plugin.py', put it into a ZIP file and import that Calibre
-# using its plugin configuration GUI.
-#
-# Changelog
-#  0.01 - Initial version
-#  0.02 - Huffdic compressed books were not properly decrypted
-#  0.03 - Wasn't checking MOBI header length
-#  0.04 - Wasn't sanity checking size of data record
-#  0.05 - It seems that the extra data flags take two bytes not four
-#  0.06 - And that low bit does mean something after all :-)
-#  0.07 - The extra data flags aren't present in MOBI header < 0xE8 in size
-#  0.08 - ...and also not in Mobi header version < 6
-#  0.09 - ...but they are there with Mobi header version 6, header size 0xE4!
