NAME

Crypt::PRNG::RC4 - Legacy RC4-based PRNG wrapper

SYNOPSIS

### Functional interface:
use Crypt::PRNG::RC4 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::RC4;

my $prng = Crypt::PRNG::RC4->new;
my $seeded_prng = Crypt::PRNG::RC4->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

Provides an interface to the RC4-based pseudo-random number generator.

This is a thin wrapper around Crypt::PRNG with the algorithm fixed to RC4. All functions and methods accept the same arguments and return the same values as the corresponding Crypt::PRNG entries.

RC4 is provided for compatibility with legacy code only and is not recommended for new designs.

EXPORT

Nothing is exported by default.

You can export selected functions:

use Crypt::PRNG::RC4 qw(random_bytes random_string);

Or all of them at once:

use Crypt::PRNG::RC4 ':all';

FUNCTIONS

All functions below behave exactly like the corresponding Crypt::PRNG functions, but use a hidden Crypt::PRNG::RC4 object internally.

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

See "irand" in Crypt::PRNG.

METHODS

Unless noted otherwise, assume $prng is an existing Crypt::PRNG::RC4 object created via new.

new

my $prng = Crypt::PRNG::RC4->new;
my $seeded_prng = Crypt::PRNG::RC4->new($seed);

Creates a PRNG object using the RC4 algorithm. If $seed is omitted, the object is automatically seeded by the underlying Crypt::PRNG logic. If $seed is provided it must be at least 5 bytes long; empty or shorter seeds fail during initialization.

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

See "string_from" in Crypt::PRNG.

double

See "double" in Crypt::PRNG.

int32

See "int32" in Crypt::PRNG.
