SHA-384 (see Reference [4]) is one of the SHA-2 hashing algorithms and has a hash digest size of 384 bits. The SHA-384 benchmark consists of hashing a variable length message in one go. The duration of a SHA-384 hashing operation is affected only by the input length. We used input lengths of 64, 8k, and 16k bytes.
