Khan Academy: Xor Bitwise Operation
If you've seen the lesson on the one-time pad, you know that it is the ultimate shift cipher. It involves the application of a random list of shifts equal to the length of the message. It's important to understand exactly how and why the...

Khan Academy: Xor and the One Time Pad
This article focuses on cipher codes especially XOR and the one-time pad. Let's look at a visual examples to see the different scrambling effects of AND vs. OR vs. XOR by encrypting an image. Here is a digital image of Charles Babbage.
