NAME
Digest::HMAC - Keyed-Hashing for Message AuthenticationSYNOPSIS
# Functional style use Digest::HMAC qw(hmac hmac_hex); $digest = hmac($data, $key, \&myhash); print hmac_hex($data, $key, \&myhash); # OO style use Digest::HMAC; $hmac = Digest::HMAC->new($key, "Digest::MyHash"); $hmac->add($data); $hmac->addfile(*FILE); $digest = $hmac->digest; $digest = $hmac->hexdigest; $digest = $hmac->b64digest;
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.
