NAME

6       Crypt::Mac::Poly1305 - Message authentication code Poly1305 (RFC 7539)
7

SYNOPSIS

9          ### Functional interface:
10          use Crypt::Mac::Poly1305 qw( poly1305 poly1305_hex );
11
12          # calculate MAC from string/buffer
13          $poly1305_raw  = poly1305($key, 'data buffer');
14          $poly1305_hex  = poly1305_hex($key, 'data buffer');
15          $poly1305_b64  = poly1305_b64($key, 'data buffer');
16          $poly1305_b64u = poly1305_b64u($key, 'data buffer');
17
18          ### OO interface:
19          use Crypt::Mac::Poly1305;
20
21          $d = Crypt::Mac::Poly1305->new($key);
22          $d->add('any data');
23          $d->addfile('filename.dat');
24          $d->addfile(*FILEHANDLE);
25          $result_raw  = $d->mac;     # raw bytes
26          $result_hex  = $d->hexmac;  # hexadecimal form
27          $result_b64  = $d->b64mac;  # Base64 form
28          $result_b64u = $d->b64umac; # Base64 URL Safe form

DESCRIPTION

31       Provides an interface to the Poly1305 message authentication code (MAC)
32       algorithm.
33

EXPORT

35       Nothing is exported by default.
36
37       You can export selected functions:
38
39         use Crypt::Mac::Poly1305 qw(poly1305 poly1305_hex );
40
41       Or all of them at once:
42
43         use Crypt::Mac::Poly1305 ':all';
44

FUNCTIONS

46   poly1305
47       Logically joins all arguments into a single string, and returns its
48       Poly1305 message authentication code encoded as a binary string.
49
50        $poly1305_raw = poly1305($key, 'data buffer');
51        #or
52        $poly1305_raw = poly1305($key, 'any data', 'more data', 'even more data');
53
54   poly1305_hex
55       Logically joins all arguments into a single string, and returns its
56       Poly1305 message authentication code encoded as a hexadecimal string.
57
58        $poly1305_hex = poly1305_hex($key, 'data buffer');
59        #or
60        $poly1305_hex = poly1305_hex($key, 'any data', 'more data', 'even more data');
61
62   poly1305_b64
63       Logically joins all arguments into a single string, and returns its
64       Poly1305 message authentication code encoded as a Base64 string.
65
66        $poly1305_b64 = poly1305_b64($key, 'data buffer');
67        #or
68        $poly1305_b64 = poly1305_b64($key, 'any data', 'more data', 'even more data');
69
70   poly1305_b64u
71       Logically joins all arguments into a single string, and returns its
72       Poly1305 message authentication code encoded as a Base64 URL Safe
73       string (see RFC 4648 section 5).
74
75        $poly1305_b64url = poly1305_b64u($key, 'data buffer');
76        #or
77        $poly1305_b64url = poly1305_b64u($key, 'any data', 'more data', 'even more data');
