Adobe ADEPT DRM for EPUB circumvented

[pietvo]

Yes, you can use your old key.

# ineptkey.pyw, version 4

# To run this program install Python 2.6 from http://www.python.org/download/
#
# and PyCrypto from http://www.voidspace.org.uk/python/m...shtml#pycrypto
#
# (make sure to install the version for Python 2.6). Save this script file as
# ineptkey.pyw and double-click on it to run it. It will create a file named
# adeptkey.der in the same directory. This is your ADEPT user key.

#
# Revision history:
#
# 1 - Initial release, for Adobe Digital Editions 1.7
# 2 - Better algorithm for finding pLK; improved error handling
# 3 - Rename to INEPT
# 4 - quick beta fix for ADE 1.7.2 - for older versions use ineptkey v3
# or upgrade to ADE 1.7.2 (anon)

What happens if you reformat your computer and install Digital Editions. Could you still use your "old key" or will the key have changed?

[pietvo]

If you do that, you will still be able to read your old ebooks. Therefore the old key should still work to decrypt. It is related to your Adobe ID, not to any particular device. You can also just copy your ebooks from one device to another. You can do that without ADE, just by dragging or using your OS's copy command. There is no conversion involved and therefore it must be the same key.

It is just that with the new version of ADE the storage of the key on your computer has changed. They took the old key and applied some kind of encryption to it before they stored it.

If you have already saved your key in a file it doesn't matter on which computer you're working. If you reinstall, install ADE and copy the keys back to the registry it only works if you have the same windows username.

By the way, you might try ineptkey_v4 with 1.7.2 ...

Cabbages only has v3 on his blog. Where did you get v4, and how can I get it?


Thanks,

Where is v4 hosted?

edit: posted too late, it's already been asked.

Ok v4 s adjusted and it should work for 1.7.1 and 1.7.2

(for the retro guys who still want the old ADE feeling ) ...

[pietvo]

I googled for "quick beta fix"

It doesn't work with Windows 7 and 1.7.2 upgraded from 1.7.1. So there is no need to bother to find it.

[pietvo]

I dom't have Windows so I couldn't check, but I looked into the code and the file that I found can't work. It is incomplete. Maybe there is a version somewhere else that is more complete.

It depends on how much registry entries you have in your registry.

[joblack]

The script differentiate with the

FileVersion

registry entry in HKEY_CURRENT_USER\\Software\\Adobe\\Digital Editions\\ if 1.7.1 or 1.7.2 is running.

Which FileVersion registry entry was the very first 1.7.2 (it can be also checked with File Properties on DigitalEditions.exe and details (file version)).

I did say this doesn't work on my system. Well, I made a simple code change and now it works. I cannot say it works on all systems. But it does work on mine which is Windows 7 with ADE 1.7.2 upgraded from 1.7.1.
