=head1 SYNOPSIS
use Crypt::Stream::Sober128;
# encrypt
$key = "1234567890123456";
$iv = "123456789012";
$stream = Crypt::Stream::Sober128->new($key, $iv);
$ct = $stream->crypt("plain message");
# decrypt
$key = "1234567890123456";
$iv = "123456789012";
$stream = Crypt::Stream::Sober128->new($key, $iv);
