Hashing, MAC, and Digital Signatures
When you don't get to program certain technologies in your every day work you do tend to forget them, this was why I started my original blog over at blogger.com. I needed a place where I could write about and remember them.
A group of technologies I nealry forgot about was the differences in hashing, message authentication codes (MAC) and digital signatures. So I wrote an article on them as a means to remind myself of what they are and how they work. Hopefully it may prove useful to someone else so here it is.
