Crypt::PRNG::Fortuna - Cryptographically secure PRNG based on Fortuna algorithm

   ### Functional interface:
   use Crypt::PRNG::Fortuna qw(random_bytes random_bytes_hex random_bytes_b64 random_bytes_b64u
                               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::Fortuna;
   $prng = Crypt::PRNG::Fortuna->new;
   #or
   $prng = Crypt::PRNG::Fortuna->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;
