I am not sure if this post belongs in this forum or not... but... I am planing on creating a program that provides the features of a text editor, but also lets you encrypt a file. I plan to do this in the wxWidgets GUI toolkit, to which I am fairly comfortable with. Does anyone have any tips or ideas for how to encrypt a file? I know very little about encyption, but I wasn't planing on using or creating a complex encryption style, just enough to keep a group of un-educated people out of my files. I was thinking of simply adding 3 to all Unicode characters (so the character originally inputed would be 3+ whatever it was;For example, A would be D) but that seemed much to simple to use.
