Problems with Adobe/ACSM
couldwenot opened this issue · comments
Question / bug report
I used DeACSM/DeDRM to open an ACSM file a few days ago, but today it isn't working. Nothing had changed from when I opened the file the first time, and today I updated both calibre and DeDRM to the latest versions. A friend sent me the actual epub, too, but that epub gives the error message "this book is locked by DRM."
Which version of Calibre are you running?
7.51
Which version of the DeDRM plugin are you running?
v10.0.9
If applicable, which version of the Kindle software are you running?
No response

Your friend's copy of the book is presumably tied to their Adobe ID. They would have to decrypt it on the computer where they downloaded it.
You downloaded your epub with DeACSM? Try manually saving the Adobe Key from DeACSM and then importing it into DeDRM's customization.
No, I got the epub version from the same person (I couldn't get the epub out of the ACSM). I assume that means they're both locked to their ID? Or is there a way I can get the Adobe Key from the epub I received?
They would need to decrypt the epub. The key would be on their computer and also encrypted.
