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();
