+# Changelog
+
+List of changes since the fork of Apprentice Harper's repository: 
+
+- 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.
+- 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.

 <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>
 
 <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>

+<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>
+
+
+<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". Clicking this button will delete the highlighted passphrase from 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>

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.

On a Mac you can find the folder at ~/Library/Application Support/Kindle/ just delete the folder 'updates' 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:

 # General Questions
 
 ## Once the DRM has been removed, is there any trace of my personal identity left in the ebook?
-The tools only remove the DRM. No attempt is made to remove any personally identifying information.
+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, 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.

 <p>Open a command prompt (terminal window) and type "calibre-debug -g" (without the quotes). Calibre will launch, and you can use the plugin 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 Apprentice Alf's blog.</p>

 DeDRM tools for ebooks

+This is a fork of Apprentice Harper's version of the DeDRM tools. I've added some of the PRs that still haven't been merged, as well as added some more features / bugfixes myself.
 
-Mostly it tracks the tools released by Apprentice Alf, athough it also includes the individual tools and their histories from before Alf had a blog.
+Take a look at [the CHANGELOG](https://github.com/noDRM/DeDRM_tools/blob/master/CHANGELOG.md) to see a list of changes since the last version by Apprentice Harper (v7.2.1). This plugin will start with version v10.0.0 so there won't be conflicting / duplicate version numbers when Apprentice Harper's version is updated again.
 
-Users should download the latest zip archive.
+The v10.0.0 versions of this plugin should both work with Calibre 5.x (Python 3) as well as Calibre 4.x and lower (Python 2). If you encounter issues with this plugin in Calibre 4.x or lower, please open a bug report.
-Developers might be interested in forking the repository, as it contains unzipped versions of those tools that are zipped to make the changes over time easier to follow.

+# Original README from Apprentice Harper
+
+This is a repository that tracks all the scripts and other tools for removing DRM from ebooks that I could find, committed in date order as best as I could manage. (Except for the Requiem tools for Apple's iBooks, and Convert LIT for Microsoft's .lit ebooks.) This includes the tools from a time before Apprentice Alf had a blog, and continues through to when Apprentice Harper (with help) took over maintenance of the tools.
+
+The individual scripts are now released as two plugins for calibre: DeDRM and Obok. 
+The DeDRM plugin handles books that use Amazon DRM, Adobe Digital Editions DRM (version 1), Barnes & Noble DRM, and some historical formats.
+The Obok plugin handles Kobo DRM.
+
+Users with calibre 5.x or later should use release 7.2.0 or later of the tools.
+Users with calibe 4.x or earlier should use release 6.8.x of the tools.
 
 For the latest Amazon KFX format, users of the calibre plugin should also install the KFX Input plugin from the standard calibre plugin menu. It's also available from the MobileRead thread here: https://www.mobileread.com/forums/showthread.php?t=291290
 
+Note that Amazon changes the DRM for KFX files frequently. What works for KFX today might not work tomorrow.
+
 I welcome contributions from others to improve these tools, from expanding the range of books handled, improving key retrieval,  to just general bug fixes, speed improvements and UI enhancements.
 
-I urge people to read the FAQs. But to cover the most common: Use ADE 2.0.1 to be sure not to get the new DRM scheme that these tools can't handle. Do remember to unzip the downloaded archive to get the plugin. You can't load the whole archive into calibre.
+I urge people to read the FAQs. But to cover the most common: Use ADE 2.0.1 to be sure not to get the new DRM scheme that these tools can't handle. Do remember to unzip the downloaded archive to get the plugin (beta versions may be just the plugin  don't unzip that). You can't load the whole tools archive into calibre.
 
 My special thanks to all those developers who have done the hard work of reverse engineering to provide the initial tools.

 The DeDRM plugin for calibre removes DRM from your Kindle and Adobe DRM ebooks when they are imported to calibre. Just install the DeDRM plugin (DeDRM_plugin.zip), following the instructions and configuration directions provided in the ReadMe file and the help links in the plugin's configuration dialogs.
 
 Once installed and configured, you can simply add a DRM book to calibre and a DRM-free version will be imported into the calibre database. Note that DRM removal only occurs on IMPORT not on CONVERSION or at any other time. If you have already imported DRMed books you'll need to remove the books from calibre and re-import them.
