You could use Crypt::Twofish2. The produced encrypted strings are multiple of 16 Bytes of length.

To convert the encrypted text to printable chars, you have to uuencode (or base64 encode) it. Example: 

use Crypt::Twofish2;
use MIME::Base64;
$cipher = new Crypt::Twofish2 "a" x 32, Crypt::Twofish2::MODE_CBC;
my $text = "random text!";
print length($text),": $text\n";
# make text a multiple of 128 bit
$text .= " " x (16 - length($text) % 16);
$crypted = encode_base64($cipher->encrypt($text));
print length($crypted),": $crypted\n";
__END__
12: random text!

Short enough and (somewhat)secure (well, the above aa.. cipher is silly :-)
