Crypt::PRNG::ChaCha20 − Cryptographically secure PRNG based on ChaCha20 (stream cipher) algorithm
### Functional
interface:
use Crypt::PRNG::ChaCha20 qw(random_bytes random_bytes_hex
random_bytes_b64 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::ChaCha20;
$prng = Crypt::PRNG::ChaCha20−>new;
#or
$prng = Crypt::PRNG::ChaCha20−>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;
