=head1 NAME

Crypt::Mac::HMAC - Message authentication code HMAC

=head1 SYNOPSIS

### Functional interface:
   use Crypt::Mac::HMAC qw( hmac hmac_hex );

# calculate MAC from string/buffer
   $hmac_raw  = hmac('SHA256', $key, 'data buffer');
   $hmac_hex  = hmac_hex('SHA256', $key, 'data buffer');
   $hmac_b64  = hmac_b64('SHA256', $key, 'data buffer');
   $hmac_b64u = hmac_b64u('SHA256', $key, 'data buffer');

### OO interface:
   use Crypt::Mac::HMAC;

$d = Crypt::Mac::HMAC->new('SHA256', $key);
   $d->add('any data');
   $d->addfile('filename.dat');
   $d->addfile(*FILEHANDLE);
   $result_raw  = $d->mac;     # raw bytes
   $result_hex  = $d->hexmac;  # hexadecimal form
   $result_b64  = $d->b64mac;  # Base64 form
   $result_b64u = $d->b64umac; # Base64 URL Safe form

=head1 DESCRIPTION

Provides an interface to the HMAC message authentication code (MAC) algorithm.

=head1 EXPORT

Nothing is exported by default.

You can export selected functions:

use Crypt::Mac::HMAC qw(hmac hmac_hex );

Or all of them at once:

use Crypt::Mac::HMAC ':all';

=head1 FUNCTIONS

=head2 hmac

Logically joins all arguments into a single string, and returns its HMAC message authentication code encoded as a binary string.

$hmac_raw = hmac($hash_name, $key, 'data buffer');
 #or
 $hmac_raw = hmac($hash_name, $key, 'any data', 'more data', 'even more data');

# $hash_name ... any <NAME> for which there exists Crypt::Digest::<NAME>
 # $key ......... the key (octets/bytes)

=head2 hmac_hex

Logically joins all arguments into a single string, and returns its HMAC message authentication code encoded as a hexadecimal string.

$hmac_hex = hmac_hex($hash_name, $key, 'data buffer');
 #or
 $hmac_hex = hmac_hex($hash_name, $key, 'any data', 'more data', 'even more data');

# $hash_name ... any <NAME> for which there exists Crypt::Digest::<NAME>
 # $key ......... the key (octets/bytes, not hex!)

=head2 hmac_b64

Logically joins all arguments into a single string, and returns its HMAC message authentication code encoded as a Base64 string.

$hmac_b64 = hmac_b64($hash_name, $key, 'data buffer');
 #or
 $hmac_b64 = hmac_b64($hash_name, $key, 'any data', 'more data', 'even more data');

# $hash_name ... any <NAME> for which there exists Crypt::Digest::<NAME>
 # $key ......... the key (octets/bytes, not Base64!)

=head2 hmac_b64u

Logically joins all arguments into a single string, and returns its HMAC message authentication code encoded as a Base64 URL Safe string (see RFC 4648 section 5).

$hmac_b64url = hmac_b64u($hash_name, $key, 'data buffer');
 #or
 $hmac_b64url = hmac_b64u($hash_name, $key, 'any data', 'more data', 'even more data');

# $hash_name ... any <NAME> for which there exists Crypt::Digest::<NAME>
 # $key ......... the key (octets/bytes, not Base64url!)

=head1 METHODS

$d->clone();

=head2 reset
