Detailed Description

SHA1 HMAC not dependent on OpenSSL.

Note

New code that needs fast or incremental HMACs should use the OpenSSL EVP_* HMAC interface instead, as that can take advantage of acceleration instructions provided by various CPUs (and provides an incremental hashing interface).

Adapted from hmacmd5.c (HMAC-MD5). Test cases from RFC2202.
