A pre-release of the DeDRM plugin only (v7.0.1) is now available.  This release REQUIRES calibre 5.x which utilizes Python 3 for plugins. Since this is the DeDRM plugin only, DO NOT unzip the downloaded file.  Load the entire zipped file as is into calibre 5.x.  To leave a comment, see this post: DRM Removal Tools for eBooks.

Pre-Release Notes

The main change over 7.0.0b4 is an update to ineptpdf.py that should allow some Adobe Digital Edition PDFs to be decrypted.

I currently only have one sample, and it works with that.

If 7.0.1 doesn’t work for your PDF, but 6.8.1 does, please send me the encrypted book and your adept.der key by email to apprenticeharper@gmail.com

I have bumped the version number just to make tracking issues easier. This is NOT a full release. Just testing the DeDRM plugin.

A pre-release of the DeDRM plugin only (v7.0.3) is now available.  This release REQUIRES calibre 5.x which utilizes Python 3 for plugins. Since this is the DeDRM plugin only, DO NOT unzip the downloaded file.  Load the entire zipped file as is into calibre 5.x.  To leave a comment, see this post: DRM Removal Tools for eBooks.

Pre-Release Notes

This has more changes to ineptpdf.py. It should now handle most PDFs from ADE, on both PC and Mac.

This change now also fixes reporting of metadata in some PDFs, and may fix other problems. This change will be back-ported to the 6.x branch in due course. (Keywords in PDFs should not have spaces, but an encoding of %20 was getting converted into a space on reading in the PDF, and not converted back again. This seems to be a long-standing bug.)

I think I’ve also updated the version number correctly this time.

Release Notes

This release is for calibre 5.x. It includes the DeDRM and Obok plugins, versions 7.1.0.

For calibre 4.23, you must use the 6.8.1 DeDRM plugin, but the included Obok 7.1.0 plugin should work with calibre 4.2.3.

There may well still be problems with the DeDRM plugin. If you find a book that can be decrypted with calibre 4.23 and DeDRM 6.8.1, but that does not decrypt with DeDRM 7.1.0, please send me the original encrypted book, and your key exported from the DeDRM 6.8.1 preferences. I will try to reproduce the problem and fix the bug. Please send books and keys to apprenticeharper@gmail.com

Please DO NOT send me anything unless you can get it to decrypt successfully with calibre 4.23 and DeDRM 6.8.1

Release Notes 7.2.0

This release incorporates numerous small bug fixes contributed through pull requests to the GitHub repository. Thank you to all contributors.

It also now includes code that should handle the latest KFX encryption used by the latest Kindle for PC and Kindle for Mac. How long this code will work is anyone’s guess. It may be that Amazon will update Kindle for PC/Mac very quickly. In which case, the existing work-arounds to get KF8 format should still work.

I am very grateful to those dedicated developers who spend their free time reverse-engineering the DRM code.

Release Notes 7.2.1

I messed up some white space. I still haven’t got KFX to work for me, but I don’t think I’ve actually broken anything this time.
