NAME

Crypt::Stream::RC4 − Stream cipher RC4

SYNOPSIS

use Crypt::Stream::RC4;
# encrypt
$key = "1234567890123456";
$stream = Crypt::Stream::RC4−>new($key);
$ct = $stream−>crypt("plain message");
# decrypt
$key = "1234567890123456";
$stream = Crypt::Stream::RC4−>new($key);
$pt = $stream−>crypt($ct);

DESCRIPTION

Provides an interface to the RC4 stream cipher.

METHODS

new

$stream = Crypt::Stream::RC4−>new($key);
# $key .. length 5−256 bytes (40 − 2048 bits)

crypt

$ciphertext = $stream−>crypt($plaintext);
#or
$plaintext = $stream−>crypt($ciphertext);

keystream

$random_key = $stream−>keystream($length);

clone

$stream−>clone();
