=head1 NAME

Crypt::Stream::Sober128 - Stream cipher Sober128

=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);
   $pt = $stream->crypt($ct);
