After decrypting the ePub I can simply convert it to LRF and upload it to my PRS-500 using Calibre. I use the very same method for books from the Kindle store.

OK, Erwin, I understand now what your situation is. Thanks for spelling it out.
The following is for the benefit of others who may be in the same situation:
My
ADEPTKey Generator 1.1a AppleScript (download it
link removed) works under Mac OS X 10.5 "Leopard" or 10.6 "Snow Leopard" to extract from your
~/Library/Application Support/Adobe/Digital Editions/activation.dat file a cryptographic key which it puts in a new file,
adeptkey.der. (You can put that
adeptkey.der on the desktop or in any folder you want to, and you can change the name of the output file to whatever you want.)
adeptkey.der (or whatever you chose to call it) then is used by the
ineptepub.pyw Python script when you decrypt (remove the Digital Rights Management encryption of) an Adobe Digital Editions e-book. The output of
ineptepub.pyw is an unencrypted .epub file that you can use in any way that you can any other EPUB e-book.
Erwin (evdberg) has an
activation.dat file that was
not generated by the Adobe Digital Editions software.
ADEPTKey Generator 1.1a does not work with
activation.dat files such as Erwin's that come from the Sony Reader software on a Mac -- unless you do what Erwin did and edit the Sony Reader
activation.dat file.
