ineptepub.pyw error: Problem decrypting session key

[JustinG87]

So I've read over the various posts regarding breaking the DRM for Sony epub books and have tried to do it myself, which has resulted in the 'Problem decrypting session key' error. I've tried a multitude of the suggested fixes, including downgrading to a previous Reader Edition version, using different versions of the ineptepub and ineptkey scripts, so on and so forth. I'm running all this on Windows XP (which is actually run via Parallels on my MacBook Pro) and using new copies of the epub files downloaded from Sony's Reader Library on the same Windows system. Does anyone have any suggestions? I have an iPad now and Sony's pissing me off with this 'you can't use books you have legally purchased on any system or reader other than our own' crap. Thank you for your help!

I have to say that also. Tried everything in this thread multiple times - no luck. I have several adobe epub books from Sony and am using Windows 7 64 bit

I had similar problems so I unloaded everything and reloaded it and it worked.

Hi,
Thanks for your reply

I checked my rights.xml file:
It contains the html code

<?xml version="1.0"?><adept:rights xmlns:adept="http://ns.adobe.com/adept"><licenseToken xmlns="http://ns.adobe.com/adept">

and also tried unistalling the ADE 1.7.2 and installing older version and then by generating the new key using ineptkey.pyw script. version 3 and ineptepub.pyw, version 2. Then also I got the Same error as

Error: Problem decrypting session key

And I tried and second solution

Solution #2:

1. Just uninstall the new version, delete the ADEPT folder in the Registry.
HKEY_CURRENT_USER>Software>Adobe>ADEPT
2. Delete the My Digital Editions folder in My Documents.
3. Reboot computer.
4. Re-install the old version provided in the link below.
Code:

(check all downloads with VirusTotal or any good antivirus)
5. Reactivate ADE.
6. Run the Ineptkey again to obtain the Adeptkey.der.
7. Then you should be good to go.

But this too fails..

Plz let me know what I have to do to break the drm.

@gauthamb
As you can see above, several other users had a similar problem and tried to follow the above mentioned steps several times. It worked for them, so it should work for you as well.

Also try ineptkey.pyw version 4.3 and aineptepub.pyw as mentioned above.

I too am getting the "problem decrypting session key", and would like to roll back to 1.7.1 of ADE, but can't get the link: http://drop.io/a1bdxlq to work.

Is the installer for 1.7.1 still there?

Ok, please ignore this. I installed the 4.3 version of ineptkey and it's all good.

Thanks for all your work on this stuff, this is very useful and helpful for those of us with a big investment in Sony Reader Library purchases who now want to switch to the iPad.

Please remember that iPad screens are similar to computer screens, so Sony Reader, Amazon Kindle and other readers that use eInk technology are much better for your eyes.

Hi,

I have the exact same problem as many here: "error: problem decrypting session key". I downgraded to ADE 1.7.1 after deleting ADEPT and rebooting as suggested. I'm using ineptkey.pyw 4.3 and aineptepub.pyw 4.1 also as suggested. No dice. One issue: the epubs were originally downloaded from a different computer than this one, and if I try to add one to the ADE library it says "Document is licensed for a different user account". Is this an issue? The computer originally used to download the epubs is currently kaput. Am I out of luck? Or is there a solution?

Thanks in advance.
