I don't want to use Open SSL or any very big none-built-in libraries for this. I only want to be able to encrypt a string with a key so you can't decrypt it without it.

By the way, i already did a long search on stackoverflow and i've checked out those unsecure ways but i want something robust like md5 (which can be decrypted with a key).

Thanks
