What is sha96?

HMAC-SHA–96. In the System Management Agent, the Secure Hash Algorithm (SHA) implementation is HMAC-SHA–96. This one-way encryption uses a 96–bit hash and a 20–octet key length. The algorithm takes as input a message of less than 264 bits in length. The input message is processed in 512–bit blocks.
