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);

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