NAME

Digest::HMAC - Keyed-Hashing for Message Authentication

SYNOPSIS

 # 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.
