This was the first encryption software I ever made. I make games more often. I made it for a friend who wanted it real fast and couldn't tell any better. One of the reasons I don't post here very often is that when I do, I always get some guy who knows the area 100x better than I do and shoots down my work. Also, I just realized that the code is in the rar file. I did not mean to put it there.
A friend asked me for a file encrypter a while ago, so I wrote one in console. He just told me that it has been really useful for him and I should consider giving it to other people. It just asked you to drag and drop the file on the screen, and it encrypts it with a key you can use to decrypt it from the same program.
Anyway, it is rar'd with this post if you want it.
