# Documentation

data IV k #

Initilization Vectors for BlockCipher implementations (IV k) are used for various modes and guarrenteed to be blockSize bits long. The common ways to obtain an IV are to generate one (`getIV` or `getIVIO`) or to use one provided with the ciphertext (using the `Serialize` instance of IV).

`zeroIV` also exists and is of particular use for starting `ctr` mode with a fresh key.
