Initialization Vector (IV) We use an IV in a cryptographic algorithm as a starting state, adding this to a cipher to hide patterns in the encrypted data. This helps avoid the need to re-issue a new key after each invocation. 3.1. Properties of an IV. We use a unique sequence or an IV for most modes of encryption.
