Crypt::PRNG::Fortuna(3User Contributed Perl DocumentaCrypt::PRNG::Fortuna(3pm)
NAME
Crypt::PRNG::Fortuna - Cryptographically secure PRNG based on Fortuna
algorithm
SYNOPSIS
### Functional interface:
use Crypt::PRNG::Fortuna qw(random_bytes random_bytes_hex random_bytes_b64 random_bytes_b64u
random_string random_string_from rand irand);
$octets = random_bytes(45);
$hex_string = random_bytes_hex(45);
$base64_string = random_bytes_b64(45);
$base64url_string = random_bytes_b64u(45);
$alphanumeric_string = random_string(30);
$string = random_string_from('ACGT', 64);
$floating_point_number_0_to_1 = rand;
$floating_point_number_0_to_88 = rand(88);
$unsigned_32bit_int = irand;
### OO interface:
use Crypt::PRNG::Fortuna;
$prng = Crypt::PRNG::Fortuna->new;
#or
$prng = Crypt::PRNG::Fortuna->new("some data used for seeding PRNG");
$octets = $prng->bytes(45);
$hex_string = $prng->bytes_hex(45);
$base64_string = $prng->bytes_b64(45);
$base64url_string = $prng->bytes_b64u(45);
$alphanumeric_string = $prng->string(30);
$string = $prng->string_from('ACGT', 64);
$floating_point_number_0_to_1 = rand;
$floating_point_number_0_to_88 = rand(88);
$unsigned_32bit_int = irand;
