Encrypting and Decrypting a text file

Hello!

I am making a program that created a very imporant textfile database of important user information that only the program itself should be able to read. So I want to have the program decrypt it upon running, and encrypt it again when closing the program. How would this be done? I am kind of a newbie. :smile:

Thanks

I've recently completed a program that opens and saves encrypted files, which it can decode,
All you I think you should do is open the file to a string, decode the string, and display it, and when you save, copy the text from the box into a string, encode the string and save that.
if you want to see my source code email, it's a bit big 282K, so I'll email it to you if you want it
you might find it useful
