WebEncryption Using Hash! Use shared secret to generate hash! Continually hash the hash to generate one-time pad! XoR the pad to message! Issue: If some one knows the plain text, they can compute the pad and use it to send another message! Solution: " Use IV " Use cipher block chaining K AB Hash Hash Hash Hash Pad Message WebIn cryptography, an initialization vector ( IV) or starting variable ( SV) [1] is an input to a cryptographic primitive being used to provide the initial state. The IV is typically required to be random or pseudorandom, but sometimes an IV only needs to …

WebThis is normally used for hashing algorithms, in order to get a different hash on each run of hashing of the same message. You do not need to use a salt with AES-CBC, because the IV is already having the effect that the salt is designed to have. But if you want to use a salt, you can, and here is what would happen.
