May 3	comment	CBC-MAC , fixed length, all blocks returned I'm not seeing a practical use of this. I just want to know, in theory, why this is insecure.

Nov 19	comment	Using CBC with a fixed IV and a random first plaintext block I guess it will spend an additional block per cipher operation. Can't see where it is linear the size of the ciphertext.
Nov 19	comment	Using CBC with a fixed IV and a random first plaintext block You didn't answer my question. I asked if this approach is considered as safe as the classical CBC with random IV.
