I have this idea bout making a cryptography program that will encrypt pictures. I know that you can do this with PGP, but I mean it in a little different way. What I want to do is this: You have opened a picture in, ACDSee for example, and you want some of the picture only for a certain person. So you chose that part of the picture, encrypt it, and send it to the person you want. What do you guys think?
Jan, I can't say that I full understand what you're doing, or maybe I just don't see why you're doing it. If you mean that you want to take part of a picture and encrypt it and send it to someone, couldn't you just crop the desired section of the image out and save it as a different file, then encrypt it via PGP, etc. I don't see how encrypting part of a picture is any different than, say.. cutting part of a text file out and saving it to another file and encrypting that portion of it. That isn't to say that if you had some new form of encryption that it wouldn't be worth exploring, only that I tend to question the originality or usefulness (relative to current, widely available crypto technology) of your concept. Maybe you could explain it in more detail to us. ...Jason Sloderbeck stom@uit.net Plasmic Computer Systems
