NAME
Crypt::Stream::Sober128 - Stream cipher Sober128
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);DESCRIPTION
Provides an interface to the Sober128 stream cipher.
