Decryption of client-side encrypted Texts in Evernote notes (OLD encryption RC2 64 Bit) #632

This is a follow-up issue to my reported issue from 2023-11-01.

Thank you for the fix - some encrypted texts are now correctly decrypted.

But Evernote used TWO different encryption algorithms over the years. 1) Old one: RC2 encryption with 64 bit key 2) New one (since a few years): AES encryption with 128 bit key

The new AES texts get decrypted now (thanks to your bugfix in 01/2024). But the old encrypted texts get NOT yet decrypted.

Would be very cool, if you could fix it. Thanks a lot.

Michael
