## NAME
    [Crypt::PRNG::Fortuna] - Cryptographically secure PRNG based on Fortuna
    algorithm

## SYNOPSIS
       ### 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;
