NAME

6       Crypt::PRNG::ChaCha20 - Cryptographically secure PRNG based on ChaCha20
7       (stream cipher) algorithm

SYNOPSIS

10          ### Functional interface:
11          use Crypt::PRNG::ChaCha20 qw(random_bytes random_bytes_hex random_bytes_b64 random_string random_string_from rand irand);
12
13          $octets = random_bytes(45);
14          $hex_string = random_bytes_hex(45);
15          $base64_string = random_bytes_b64(45);
16          $base64url_string = random_bytes_b64u(45);
17          $alphanumeric_string = random_string(30);
18          $string = random_string_from('ACGT', 64);
19          $floating_point_number_0_to_1 = rand;
20          $floating_point_number_0_to_88 = rand(88);
21          $unsigned_32bit_int = irand;
22
23          ### OO interface:
24          use Crypt::PRNG::ChaCha20;
25
26          $prng = Crypt::PRNG::ChaCha20->new;
27          #or
28          $prng = Crypt::PRNG::ChaCha20->new("some data used for seeding PRNG");
29
30          $octets = $prng->bytes(45);
31          $hex_string = $prng->bytes_hex(45);
32          $base64_string = $prng->bytes_b64(45);
33          $base64url_string = $prng->bytes_b64u(45);
34          $alphanumeric_string = $prng->string(30);
35          $string = $prng->string_from('ACGT', 64);
36          $floating_point_number_0_to_1 = rand;
37          $floating_point_number_0_to_88 = rand(88);
38          $unsigned_32bit_int = irand;
