The problem arises in the encdata, i am trying to use it to encrypt a variable that the user inputs and it does the encryption process correctly but the decryption process doesn't seem to work. 

If you replace the variable $input with the acutal hexadecimal numbers that the user inputs it works perfectly fine. I was wondering why is this and how do i solve this issue?

Use the help (F1 in Scite): AutoIt comes with standard UDFs, one of them being Crypt.au3

bahjat,

When you post code please use Code tags - see here how to do it. Then you get a scrolling box and syntax colouring as you can see above now I have added the tags.
