A simple example of how a one-time pad works is shown in the example below. Here, we have a plaintext message ofTEST. We also have a random secret key ofFVEB, which is the same length as the message sent. Using the simple process of assigning a letter to a number, the plaintext ...
If an organization has the resources to create strong random numbers for the secret key used by a one-time pad, a common mistake is to reuse components of a one-time pad. For example, if an adversary has access to the ciphertext produced by one-time pads and one key is reused, the ...

This is a little better if you don't want to just keep the same notes open all the time. Here's my version. I'm a little biased, but I think it's the best. Make sure to change your e-mail address in the snippet from email@example.com to whatever your personal address is. ...

If you're using a mouse or trackpad, you can perform actions more quickly by moving your mouse pointer to one of the 4 corners of the screen. For example, set the top right corner to Volume up and the bottom right corner to Volume down to quickly control the volume using your mouse....
