This STANDARD describes a keyed-hash message authentication code (HMAC), a
mechanism for message authentication using cryptographic hash functions. HMAC can
be used with any iterative Approved cryptographic hash function, in combination with a
shared secret key. The cryptographic strength of HMAC depends on the properties of the
underlying hash function. The HMAC specification in this STANDARD is a generalization of
Internet RFC 2104, HMAC, Keyed-Hashing for Message Authentication, and ANSI
X9.71, Keyed Hash Message Authentication Code.
