Hey all,
I have a little problem here.. i need to encrypt a 4 character string and be able to decrypt it later on. The result may not be longer as 8 characters so i cant use md5.. anyone has a good idea?
Example:
$str = \'Que1\'
some cloud of code
echo $str --> some crap
some cloud of code
echo $str --> Que1
I know its possible to mess around with chars myself but it must not look logical to someone.. a mega encryption is not needed..

If I was you, I'd write my own encryption/decryption functions. Probably the only way you're gonna be able to meet your needs, plus it wouldn't be that hard for you to do/figure out.
Josh.. i was thinking the same when i readed my msg again.. i know its not hard .. not at all.. but i hate to invent the wheel again.. i hoped there was some sort of function for this ..
Thnxz for the post

It's one of those things you just toss off at the wrist, so to speak
First thing I thought - four random chars, XOR them with the four chars of the msg, then interleave the random and XORed chars.
