WebThe CBC mode produces the same ciphertext whenever the same plaintext is encrypted using the same key and starting variable. The chaining operation makes the ciphertext blocks dependent on the current and all preceding plaintext blocks and therefore blocks can not be rearranged. WebRules for Bearer SAST.
