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
