Crypt::PRNG::Sober128 - Cryptographically secure PRNG based on Sober128 (stream cipher) algorithm

### Functional interface:
use Crypt::PRNG::Sober128 qw(random_bytes random_bytes_hex random_bytes_b64 random_bytes_b64u random_string random_string_from rand irand);
my $octets = random_bytes(45);
my $hex_string = random_bytes_hex(45);
my $base64_string = random_bytes_b64(45);
my $base64url_string = random_bytes_b64u(45);
my $alphanumeric_string = random_string(30);
my $string = random_string_from('ACGT', 64);
my $floating_point_number_0_to_1 = rand;
my $floating_point_number_0_to_88 = rand(88);
my $unsigned_32bit_int = irand;
### OO interface:
use Crypt::PRNG::Sober128;
my $prng = Crypt::PRNG::Sober128->new;
my $seeded_prng = Crypt::PRNG::Sober128->new("some data used for seeding PRNG");
my $octets = $prng->bytes(45);
my $hex_string = $prng->bytes_hex(45);
my $base64_string = $prng->bytes_b64(45);
my $base64url_string = $prng->bytes_b64u(45);
my $alphanumeric_string = $prng->string(30);
my $string = $prng->string_from('ACGT', 64);
my $floating_point_number_0_to_1 = $prng->double;
my $floating_point_number_0_to_88 = $prng->double(88);
my $unsigned_32bit_int = $prng->int32;

Provides an interface to the Sober128-based pseudo-random number generator.

This is a thin wrapper around Crypt::PRNG with the algorithm fixed to Sober128. All functions and methods accept the same arguments and return the same values as the corresponding Crypt::PRNG entries.

Nothing is exported by default.

You can export selected functions:

use Crypt::PRNG::Sober128 qw(random_bytes random_string);

Or all of them at once:

use Crypt::PRNG::Sober128 ':all';

All functions below behave exactly like the corresponding Crypt::PRNG functions, but use a hidden "Crypt::PRNG::Sober128" object internally.

See "random_bytes" in Crypt::PRNG.

See "random_bytes_hex" in Crypt::PRNG.

See "random_bytes_b64" in Crypt::PRNG.

See "random_string" in Crypt::PRNG.

See "random_string_from" in Crypt::PRNG.

See "rand" in Crypt::PRNG.

See "irand" in Crypt::PRNG.

Unless noted otherwise, assume $prng is an existing "Crypt::PRNG::Sober128" object created via "new".

my $prng = Crypt::PRNG::Sober128->new;
my $seeded_prng = Crypt::PRNG::Sober128->new($seed);

Creates a PRNG object using the Sober128 algorithm. If $seed is omitted, the object is automatically seeded by the underlying Crypt::PRNG logic.
