Initialization vector - Wikipedia

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 be unpredictable or unique. Randomization is crucial for some encryption schemes to achieve ... WebAug 13, 2024 · If you derive a key from a password and a salt, that's a pseudorandomly derived key. From the same password and the same salt, you always get the same key. Never use a key that's derived from a password to encrypt actual data: if you ever want to change the password, you'd need to decrypt and re-encrypt the data. first science with jwst
