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

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

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

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

$stream->clone();
