Landon, Since you are the owner of the crypto code I'll leave it up to you to decide how you want to handle this. I've attached a patch for the code I wrote to make the encryption code preserve the block boundaries. If it is useful great, if not that's okay too, since I got to explore a whole section of the Bacula code I hadn't played with before. :-).

Howdy, The encryption does not include compression -- It made more sense to piggyback on the existing compression code. Also, thanks for catching this! I'm embarrassed that I forgot to test backup+restore with both compression and encryption enabled. -landonf
