# 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.

<h1>DeDRM Plugin <span class="version">(v10.0.0)</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>
|
||||
|
||||
<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>

<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>
|
||||
|
||||
<p>Once done entering/deleting passphrases, click Close to exit the customization dialogue. Your changes will only be saved permanently when you click OK in the main configuration dialog.</p>

First, unzip the archive. You should now have a DeDRM folder containing several other folders and a `ReadMe_Overview.txt` file. Please read the `ReadMe_Overview.txt` file! That will explain what the folders are, and you'll be able to work out which of the tools you need.

## 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.
|
||||
* Kindle only: It is a Topaz format book and contains some coding that the tools do not understand. You will need to get a log of the DeDRM attempt, and then create a [new issue at Apprentice Harper's github repository](https://github.com/apprenticeharper/DeDRM_tools/issues/), attaching the book and the log, so that the tools can be updated.
|
||||
|
||||
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, and post that in a comment at Apprentice Alf's blog or in a new issue at Apprentice Harper's github repository.

## 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.

## I registered Adobe Digital Editions 3.0 or later with an Adobe ID before downloading, but my epub or PDF still has DRM.
|
||||
Adobe introduced a new DRM scheme with ADE 3.0 and later. Install ADE 2.0.1 and register with the same Adobe ID. If you can't open your book in ADE 2.01, then you have a book with the new DRM scheme. These tools can't help. You can avoid the new DRM scheme by always downloading your ebooks with ADE 2.0.1. Some retailers will require ADE 3.0 or later, in which case you won't be able to download with ADE 2.0.1.

# 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.

## 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, Readium LCP, Amazon, Kobo and eReader DRM schemes.
|
||||
|
||||
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.

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.
|
||||
|
||||
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.
|
||||
|
||||
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.

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.
