This document … WebInitialization vector. In 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.
