As you mention in your other postings, you've figured out how to do that - but I recommend rather changing PHP or whatever to 128-bit CFB (and yes, it has something to do with the cipher block-size, which for AES is 128 bits). --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the "Crypto++ Users" Google Group.
