SYNOPSIS

use Crypt::Stream::Sosemanuk;

# encrypt
$key = "1234567890123456";
$iv  = "123456789012";
$stream = Crypt::Stream::Sosemanuk->new($key, $iv);
$ct = $stream->crypt("plain message");

# decrypt
$key = "1234567890123456";

crypt

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

keystream
