%description
HMAC is used for message integrity checks between two parties that share a secret key,
and works in combination with some other Digest algorithm, usually MD5 or SHA-1.
The HMAC mechanism is described in RFC 2104.

HMAC follow the common Digest:: interface, but the constructor takes the secret key
and the name of some other simple Digest:: as argument.

The hmac() and hmac_hex() functions and the Digest::HMAC->new() constructor takes an
optional $blocksize argument as well. The HMAC algorithm assumes the digester to hash
by iterating a basic compression function on blocks of data and the $blocksize should
match the byte-length of such blocks.

The default $blocksize is 64 which is suitable for the MD5 and SHA-1 digest functions.
For stronger algorithms the blocksize probably needs to be increased.
