XOR Tutorial

InfoSec Writers has a short tutorial on XOR theory. This is one of the basic ideas behind netmasks, cryptography (sessions keys negotiation!), and polymorphic viruses. It's well worth knowing how this works.

For those of you that need to know more of the basic: try to learn about TCP/IP, subnetting, DNS, and the OSI model.
