NAME¶
Crypt::PRNG::ChaCha20 - Cryptographically secure PRNG based on ChaCha20 (stream cipher) algorithm
SYNOPSIS¶
### 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;
DESCRIPTION¶
Provides an interface to the ChaCha20 based pseudo random number generator
All methods and functions are the same as for Crypt::PRNG.
