The encryption of information is as old as information itself. Ever since two people wanted to pass something along, so has there been a third party who wanted to be privy to it. This back and forth battle of creating codes, breaking them, and finding new ones has been happening quietly for thousands of years. Now, in an age when information flows freely and instantaneously, the field of cryptography is more important than ever. Watch the Full Program Here: https://youtu.be/nVVF8dgKC38 Original Program Date: June 4, 2011 The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries.

Cryptography is a complex and confusing subject. In this talk you will learn about the core components of cryptography used in software development: securing data with encryption, ensuring data integrity with hashes and digital signatures, and protecting passwords with key derivation functions. While learning how to use these components, you will also learn the best practices that drive strong cryptography. This talk won’t make you a cryptography expert but it will give you the knowledge necessary to use cryptography properly. No prior knowledge of cryptography is required for this presentation.

The ATBASH cipher actually got it's start in Hebrew text - notably in Jewish Mysticism, as it's used in translations of their religious books. The name itself is is actually an acronym of four Hebrew letters: Aleph-Tav-Beth-Shin (אתבש). The way the Atbash Cipher works is by mirroring the alphabet. By writing A to Z on a piece of paper and Z to A just below it, you've crafted an Atbash Cipher! This means that if you decode one letter B=Y, you've decoded the reverse as well Y=B. Due to the low difficulty of this encryption method, it's not often used in situations where data must remain secure - but it does make a great way to casually encode messages between friends! http://wp.me/a4aWg3-8H

In this network security video tutorial we will study and understand the working of Cipher Block Chaining (CBC) also known as CBC algorithm mode. Cipher Block Chaining (CBC) - 1. Chaining adds a feedback mechanism to a block cipher 2. The results of the encryption of the previous block are fed back into the encryption of the current block. 3. In the first step; the first block of plain text and a random block of text, called Initialization Vector (IV) is used. 4. The IV has no special meaning it is simply used to make each message unique. 5. The value of IV is generated randomly.

This is the fourth in a series about cryptography; an extremely important aspect of computer science and cyber security. It covers the XOR logical operation, that is the exclusive OR operation, explaining how it can be used to encrypt and decrypt a sequence of binary digits. XOR is an important process that is employed by many modern day ciphers. Using a spreadsheet, this video demonstrates how the XOR logical operation can be applied to a single character ASCII code to encrypt and decrypt it using the same symmetric key, and the same method.

You see, in order to become a full card-carrying member of the Royal Order you need to not only be knowledgeable about Gravity Falls - you must also be adept in code cracking. It's easy to assume that most everyone has come across basic substitution code deciphering from an early age. I know that I grew up with my fair share of spy kits and cereal box decoders - but that just doesn't seem to be the case anymore. Basic code cracking skills have seemingly disappeared from the lexicon. So, in an attempt to teach the basics to those who have had no experience at all with deciphering secret messages, I have launched Code Cracking 101 - a new miniseries to walk viewers through the various codes and ciphers used in Gravity Falls and the Royal Order of the Holy Mackerel! Before you can begin decoding messages, you first need to know what a cipher is. A cipher is a method by which you can change a message (encode) that can also be used in the same way to change the message back (decode). A cipher can take the form of a tool for someone to use to decode a message quickly, but what's important to remember about ciphers is that they're standard. Anyone who knows the method can decode or encode a message with it. The Caesar Cipher gets it's name from Emperor Julius Caesar, who used this cipher to encode messages sent between his commanding officers. He devised a substitution shift cipher - a code that replaces each letter of a written word with something else (in this case, another letter) which could be decoded by shifting two interlocking disks. Each disk of the Caesar Cipher has the alphabet (in alphabetical order) written on it, and requires a "key" in order to work. A number which accompanied the message to let the decoder know how many letter to shift the disk backwards by. So download the FREE "three letters back" Caesar Cipher I've created for the Royal Order of the Holy Mackerel (LINK ABOVE), and start decoding the messages hidden through Gravity Falls. You can also use that disk to easily decode the riddle of the Trial of Membership! As you can see, decoding messages isn't impossible once you know the basics.

XOR ciphers take advantage of Ascii encoding and basic bit switching operations. They are extremely fast, but not particularly secure when used alone, without a key exchange algorithm.
