Crypt::PRNG::ChaCha20 - phpMan

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
