AVAILABLE AT http://www.creativecrafthouse.com/index.php?main_page=product_info&cPath=135&products_id=970 A precision laser engraved wood version of this famous cipher which was used for the encryption of secret messages of the Confederacy during the American Civil War (1861-1865). Difficult to decrypt messages could be created with the Cipher Disk. It was originally designed by Francis LaBarre, a gold and silver worker, in Richmond, VA. and was based on the Vigenère Cipher system. Only 5 survive, 2 of which are in the Museum of the Confederacy in Richmond, VA. They were made from brass disks. Our version is 4.4” in diameter made from alder wood. The artwork and text font of the wheel is the same as the original so it has the same visual look. Detailed Instructions for use are included. This is something that can be used today to encode messages. For Civil War Reenactors I can laser engrave name, rank, regiment. Made in Florida by Creative Crafthouse

Today we’re going to talk about how to keep information secret, and this isn’t a new goal. From as early as Julius Caesar’s Caesar cipher to Mary, Queen of Scots, encrypted messages to kill Queen Elizabeth in 1587, theres has long been a need to encrypt and decrypt private correspondence. This proved especially critical during World War II as Allan Turing and his team at Bletchley Park attempted to decrypt messages from Nazi Enigma machines, and this need has only grown as more and more information sensitive tasks are completed on our computers. So today, we’re going to walk you through some common encryption techniques such as the Advanced Encryption Standard (AES), Diffie-Hellman Key Exchange, and RSA which are employed to keep your information safe, private, and secure. Note: In October of 2017, researchers released a viable hack against WPA2, known as KRACK Attack, which uses AES to ensure secure communication between computers and network routers. The problem isn't with AES, which is provably secure, but with the communication protocol between router and computer. In order to set up secure communication, the computer and router have to agree through what's called a "handshake". If this handshake is interrupted in just the right way, an attacker can cause the handshake to fault to an insecure state and reveal critical information which makes the connection insecure. As is often the case with these situations, the problem is with an implementation, not the secure algorithm itself.

A simple and easy-to-understand version of symmetric encryption is what is known as a substitution cipher. The key for a substitution cipher is a table that maps every possible character in the plaintext message to a different value. To encrypt a message, the sender replaces all characters in the plaintext with their value in the lookup table. To decrypt a message, the recipient reverses the process. Unfortunately, simple substitution ciphers are extremely insecure and subject to a variety of simple attacks.

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

This video discusses two main ciphers during the Civil War. The Union used a route cipher and the Confederates used a cipher wheel. The techniques in this video are a simplified version of their ciphers. Officially the Confederates used a Vigenere Cipher with the cipher wheel. This means the key shift isn't the same throughout the message. For more information, check out the Vigenere Cipher online. The Union's route cipher had two parts. The first part is they replaced important words with different words. For example, Lincoln = Oak tree. When they created their grid they still encrypted by reading along the columns; however, they didn't always read it in order. In this video we read column 1 then column 2 then column 3, etc. The union's keyword would indicate the order of the columns. For example, the keyword could tell you to read down column 3 first, then column 1, then column 4, etc.

Check out the full article at http://www.stemlittleexplorers.com/en/how-to-make-cipher-wheel/ In this video, you will learn how to make Cipher Wheel or Cipher Disc which you can use to encrypt your messages that only people you choose can decipher. All you need is some Cardboard, Scissors, Ruler, Felt pen, Pen, Pin, Divider and Colored pencils. Also, great if you have a Protractor. Ciphering your message is simple: You rotate smaller disc for X places in Y direction. Then look at the letters from a bigger circle and write the letters from the smaller circle. Now you have coded message. A person who wants to decode the message needs to have the same Cipher wheel. You only need to tell him X places and Y direction and he can then align Cipher accordingly. Now that person reads letters from the smaller circle and writes the letters from the bigger circle. This is a great STEM Technology activity that Kids can use to learn coding and patterns. They will love it because the activity is mystical and secretive. Also, it's great for learning letters.
