Hello People!
I am quite new to Qt (and programming in general). And I am making a program that requires me to encrypt a file and decrypt it after asking for a password through the program.
But I have no Idea where to start.

What I already have - A program that takes some info from the user and stores it in a simple text file.

You can XOR all characters with a value and then save them, you do the same when yo read them in order to reverse the encryption.
But that is really WEAK and I do not recommend it for serious stuff.

When you store each character in the file, change in first.

When you read each character back from the file, do the reverse change.
