Okay, this is what I am trying to do. I am attempting to create my own encrypter. I have the base encryption running, used just to encrypt a string you put in. I am going to add functionality to open a text file's contents and encrypt them, outputing them into another text file. I will be working on that later, so I might post up my questions if I can't figure it out. Anyways, this is what I need help with:
1) How do I open a file's binary code, and convert it to hex?
2) After opening it in hex, it shoud become manipulatable, such as, I can make it into a list, then change each odd charecter, correct?
3) After messing with the hex, how do I convert it back into binary, then save it?
Thank you very much in advance!
