=head1 NAME

Crypt::Mac::Poly1305 - Message authentication code Poly1305 (RFC 7539)

=head1 SYNOPSIS

   ### Functional interface:
   use Crypt::Mac::Poly1305 qw( poly1305 poly1305_hex );

   # calculate MAC from string/buffer
   $poly1305_raw  = poly1305($key, 'data buffer');
   $poly1305_hex  = poly1305_hex($key, 'data buffer');
   $poly1305_b64  = poly1305_b64($key, 'data buffer');
   $poly1305_b64u = poly1305_b64u($key, 'data buffer');

   ### OO interface:
   use Crypt::Mac::Poly1305;

   $d = Crypt::Mac::Poly1305->new($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 Poly1305 message authentication code (MAC) algorithm.

=head1 EXPORT

Nothing is exported by default.

You can export selected functions:

  use Crypt::Mac::Poly1305 qw(poly1305 poly1305_hex );

Or all of them at once:

  use Crypt::Mac::Poly1305 ':all';

=head1 FUNCTIONS

=head2 poly1305

Logically joins all arguments into a single string, and returns its Poly1305 message authentication code encoded as a binary string.

 $poly1305_raw = poly1305($key, 'data buffer');
 #or
 $poly1305_raw = poly1305($key, 'any data', 'more data', 'even more data');

=head2 poly1305_hex

Logically joins all arguments into a single string, and returns its Poly1305 message authentication code encoded as a hexadecimal string.

 $poly1305_hex = poly1305_hex($key, 'data buffer');
 #or
 $poly1305_hex = poly1305_hex($key, 'any data', 'more data', 'even more data');

=head2 poly1305_b64

Logically joins all arguments into a single string, and returns its Poly1305 message authentication code encoded as a Base64 string.

 $poly1305_b64 = poly1305_b64($key, 'data buffer');
 #or
 $poly1305_b64 = poly1305_b64($key, 'any data', 'more data', 'even more data');

=head2 poly1305_b64u

Logically joins all arguments into a single string, and returns its Poly1305 message authentication code encoded as a Base64 URL Safe string (see RFC 4648 section 5).

 $poly1305_b64url = poly1305_b64u($key, 'data buffer');
 #or
 $poly1305_b64url = poly1305_b64u($key, 'any data', 'more data', 'even more data');
