updated for version 7.4.399 Problem: Encryption implementation is messy. Blowfish encryption has a weakness. Solution: Refactor the encryption, store the state in an allocated struct instead of using a save/restore mechanism. Introduce the "blowfish2" method, which does not have the weakness and encrypts the whole undo file. (largely by David Leadbeater)
