SYNOPSIS

9          ### Functional interface:
10          use Crypt::Digest::Whirlpool qw( whirlpool whirlpool_hex whirlpool_b64 whirlpool_b64u
11                                       whirlpool_file whirlpool_file_hex whirlpool_file_b64 whirlpool_file_b64u );
12
13          # calculate digest from string/buffer
14          $whirlpool_raw  = whirlpool('data string');
15          $whirlpool_hex  = whirlpool_hex('data string');
16          $whirlpool_b64  = whirlpool_b64('data string');
17          $whirlpool_b64u = whirlpool_b64u('data string');
18          # calculate digest from file
19          $whirlpool_raw  = whirlpool_file('filename.dat');
20          $whirlpool_hex  = whirlpool_file_hex('filename.dat');
21          $whirlpool_b64  = whirlpool_file_b64('filename.dat');
22          $whirlpool_b64u = whirlpool_file_b64u('filename.dat');
23          # calculate digest from filehandle
24          $whirlpool_raw  = whirlpool_file(*FILEHANDLE);
25          $whirlpool_hex  = whirlpool_file_hex(*FILEHANDLE);
26          $whirlpool_b64  = whirlpool_file_b64(*FILEHANDLE);
27          $whirlpool_b64u = whirlpool_file_b64u(*FILEHANDLE);

29          ### OO interface:
30          use Crypt::Digest::Whirlpool;
31
32          $d = Crypt::Digest::Whirlpool->new;
33          $d->add('any data');
34          $d->addfile('filename.dat');
35          $d->addfile(*FILEHANDLE);
36          $result_raw  = $d->digest;     # raw bytes
37          $result_hex  = $d->hexdigest;  # hexadecimal form
38          $result_b64  = $d->b64digest;  # Base64 form
39          $result_b64u = $d->b64udigest; # Base64 URL Safe form

DESCRIPTION

42       Provides an interface to the Whirlpool digest algorithm.
43

EXPORT

45       Nothing is exported by default.
46
47       You can export selected functions:
48
49         use Crypt::Digest::Whirlpool qw(whirlpool whirlpool_hex whirlpool_b64 whirlpool_b64u
50                                             whirlpool_file whirlpool_file_hex whirlpool_file_b64 whirlpool_file_b64u);
51
52       Or all of them at once:
53
54         use Crypt::Digest::Whirlpool ':all';
55

FUNCTIONS

57   whirlpool
58       Logically joins all arguments into a single string, and returns its
59       Whirlpool digest encoded as a binary string.
60
61        $whirlpool_raw = whirlpool('data string');
62        #or
63        $whirlpool_raw = whirlpool('any data', 'more data', 'even more data');
64
65   whirlpool_hex
66       Logically joins all arguments into a single string, and returns its
67       Whirlpool digest encoded as a hexadecimal string.
68
69        $whirlpool_hex = whirlpool_hex('data string');
70        #or
71        $whirlpool_hex = whirlpool_hex('any data', 'more data', 'even more data');
72
73   whirlpool_b64
74       Logically joins all arguments into a single string, and returns its
75       Whirlpool digest encoded as a Base64 string, with trailing '=' padding.
76
77        $whirlpool_b64 = whirlpool_b64('data string');
78        #or
79        $whirlpool_b64 = whirlpool_b64('any data', 'more data', 'even more data');
80
81   whirlpool_b64u
82       Logically joins all arguments into a single string, and returns its
83       Whirlpool digest encoded as a Base64 URL Safe string (see RFC 4648
84       section 5).
85
86        $whirlpool_b64url = whirlpool_b64u('data string');
87        #or
88        $whirlpool_b64url = whirlpool_b64u('any data', 'more data', 'even more data');
89
90   whirlpool_file
91       Reads file (defined by filename or filehandle) content, and returns its
92       Whirlpool digest encoded as a binary string.
93
94        $whirlpool_raw = whirlpool_file('filename.dat');
95        #or
96        $whirlpool_raw = whirlpool_file(*FILEHANDLE);
97
98   whirlpool_file_hex
99       Reads file (defined by filename or filehandle) content, and returns its
100       Whirlpool digest encoded as a hexadecimal string.
101
102        $whirlpool_hex = whirlpool_file_hex('filename.dat');
103        #or
104        $whirlpool_hex = whirlpool_file_hex(*FILEHANDLE);
105
106       BEWARE: You have to make sure that the filehandle is in binary mode
107       before you pass it as argument to the addfile() method.
108
109   whirlpool_file_b64
110       Reads file (defined by filename or filehandle) content, and returns its
111       Whirlpool digest encoded as a Base64 string, with trailing '=' padding.
112
113        $whirlpool_b64 = whirlpool_file_b64('filename.dat');
114        #or
115        $whirlpool_b64 = whirlpool_file_b64(*FILEHANDLE);
116
117   whirlpool_file_b64u
118       Reads file (defined by filename or filehandle) content, and returns its
119       Whirlpool digest encoded as a Base64 URL Safe string (see RFC 4648
120       section 5).
121
122        $whirlpool_b64url = whirlpool_file_b64u('filename.dat');
123        #or
124        $whirlpool_b64url = whirlpool_file_b64u(*FILEHANDLE);
125
