Digest::HMAC(3)       User Contributed Perl Documentation      Digest::HMAC(3)

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.

SEE ALSO
       Digest::HMAC_MD5, Digest::HMAC_SHA1
