NAME

       Digest::HMAC_SHA1 - Keyed-Hashing for Message Authentication

SYNOPSIS

        # Functional style
        use Digest::HMAC_SHA1 qw(hmac_sha1 hmac_sha1_hex);
        $digest = hmac_sha1($data, $key);
        print hmac_sha1_hex($data, $key);

        # OO style
        use Digest::HMAC_SHA1;
        $hmac = Digest::HMAC_SHA1->new($key);

        $hmac->add($data);
        $hmac->addfile(*FILE);

        $digest = $hmac->digest;
        $digest = $hmac->hexdigest;
        $digest = $hmac->b64digest;
