Crypt::PRNG::ChaCha20(User Contributed Perl DocumentatCrypt::PRNG::ChaCha20(3)

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;
