Crypt::...ChaCha20(3)

💖 NAME 💖

okay bestie, welcome to the Crypt::...ChaCha20(3) page from User Contributed Perl Documentation ✨ This one is all about:

Crypt::PRNG::ChaCha20 — a cryptographically secure PRNG based on the ChaCha20 (stream cipher) algorithm 💅

---

✨ SYNOPSIS ✨

### Functional interface:
use Crypt::PRNG::ChaCha20 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::ChaCha20;

my $prng = Crypt::PRNG::ChaCha20->new;
my $seeded_prng = Crypt::PRNG::ChaCha20->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;

🦋 DESCRIPTION 🦋

So this module provides an interface to the ChaCha20-based pseudo-random number generator 🎀

It’s a thin wrapper around Crypt::PRNG with the algorithm fixed to ChaCha20. All functions and methods accept the same arguments and return the same values as the corresponding Crypt::PRNG entries. no cap, that’s the whole vibe 💫

---

🎀 EXPORT 🎀

Nothing is exported by default. respectfully, it’s keeping boundaries 🙈

You can export selected functions:

use Crypt::PRNG::ChaCha20 qw(random_bytes random_string);

Or all of them at once:

use Crypt::PRNG::ChaCha20 ':all';

🫶 FUNCTIONS 🫶

All functions below behave exactly like the corresponding Crypt::PRNG functions, but use a hidden "Crypt::PRNG::ChaCha20" object internally. iykyk 👑

random_bytes

See "random_bytes" in Crypt::PRNG. 💖

random_bytes_hex

See "random_bytes_hex" in Crypt::PRNG. ✨

random_bytes_b64

See "random_bytes_b64" in Crypt::PRNG. 🎀

random_bytes_b64u

See "random_bytes_b64u" in Crypt::PRNG. 🦋

random_string

See "random_string" in Crypt::PRNG. 🌸

random_string_from

See "random_string_from" in Crypt::PRNG. 💅

rand

See "rand" in Crypt::PRNG. 🫶

irand

---

👑 METHODS 👑

Unless noted otherwise, assume $prng is an existing "Crypt::PRNG::ChaCha20" object created via "new". bestie, keep that in mind 🧠💖

new

my $prng = Crypt::PRNG::ChaCha20->new;
my $seeded_prng = Crypt::PRNG::ChaCha20->new($seed);

Creates a PRNG object using the ChaCha20 algorithm. If $seed is omitted, the object is automatically seeded by the underlying Crypt::PRNG logic. cute, automatic, iconic ✨

bytes

See "bytes" in Crypt::PRNG. 💜

bytes_hex

See "bytes_hex" in Crypt::PRNG. 🌈

bytes_b64

See "bytes_b64" in Crypt::PRNG. 🍓

bytes_b64u

See "bytes_b64u" in Crypt::PRNG. 🧚

string

See "string" in Crypt::PRNG. 🎀

string_from
