NAME

6       Crypt::PRNG::Fortuna - Cryptographically secure PRNG based on Fortuna
7       algorithm

SYNOPSIS

10          ### Functional interface:
11          use Crypt::PRNG::Fortuna qw(random_bytes random_bytes_hex random_bytes_b64 random_bytes_b64u
12                                      random_string random_string_from rand irand);
13
14          $octets = random_bytes(45);
15          $hex_string = random_bytes_hex(45);
16          $base64_string = random_bytes_b64(45);
17          $base64url_string = random_bytes_b64u(45);
18          $alphanumeric_string = random_string(30);
19          $string = random_string_from('ACGT', 64);
20          $floating_point_number_0_to_1 = rand;
21          $floating_point_number_0_to_88 = rand(88);
22          $unsigned_32bit_int = irand;
23
24          ### OO interface:
25          use Crypt::PRNG::Fortuna;
26
27          $prng = Crypt::PRNG::Fortuna->new;
28          #or
29          $prng = Crypt::PRNG::Fortuna->new("some data used for seeding PRNG");
30
31          $octets = $prng->bytes(45);
32          $hex_string = $prng->bytes_hex(45);
33          $base64_string = $prng->bytes_b64(45);
34          $base64url_string = $prng->bytes_b64u(45);
35          $alphanumeric_string = $prng->string(30);
36          $string = $prng->string_from('ACGT', 64);
37          $floating_point_number_0_to_1 = rand;
38          $floating_point_number_0_to_88 = rand(88);
39          $unsigned_32bit_int = irand;
