Cipher

(male narrator) So now we're gonna encrypt the message: "Meet at First and Pine at midnight," using a transposition cipher with rows eight characters long. Specifically,...

The answer is there is always exactly 1. For any message ciphertext pair, there is one key that maps that message to that ciphertext. We can see that thinking about the nature of the one-time pad....

(male narrator) So one way to make a shift cipher, uh... a little more complicated into full frequency analysis, is to, uh...change the shift after each character. So this time, we're gonna...

Appreciate life and live good anytime that you get the chance cause the shit that i done seen a make the average person shit in they pants the broad had a healthy gorgeous ass and i'm staring...

I always knew I'd make the front page one day. Just not like this. Spy isn't a label to be borne lightly these days. This is sure to attract the attention of the feeds. Just what you...

So in unit one, we learn about symmetric ciphers. In unit two, we're going to learn about how to apply symmetric ciphers to solve problems. So for the rest of this course, we are mostly going...

The second problem--the decision about what ciphers and hash functions to use--is based on these clear text messages. An attacker who tampers with these can make the client and server use some very...

The first machine that was built to do this was called the Heath Robinson. It was named after this British cartoonist who drew cartoons of crazy machines to do operations. This one was for peeling...

[Evans] So we've reached the end of Unit 1. Let me remind you what we've covered. We covered symmetric cryptosystems and introduced the terminology and definitions we need to talk...

Hello and welcome to my Mists of Pandaria Affliction Warlock quick look. In this video I'm going to try to explain the changes and rotation differences between the current Affliction skillset...
