## 3DES

The Triple Data Encryption Standard was derived (3DES) was derived from DES, when DES began to falter as a secure form of encryption and before AES was developed.

## ADFGVX Cipher

The ADFGVX cipher was developed by Colonel Fritz Nebel and introduced in March 1918. Germany used it as a field cipher during WWI. It was named the ADFGVX cipher for the letters used to create ciphertext, chosen for their distinctiveness in morse…

## AES

The Advanced Encryption Standard (AES) is a symmetric block cipher that was began development in 1997 to replace the Data Encryption Standard. It chosen as the U.S. federal government standard encryption algorithm in 2002. In 2003, it became the…

## Affine Cipher

The Affine Cipher is a form of substitution cipher that involves math. The shift of the alphabet- while transpositioning plaintext into ciphertext is determined by a mathematical equation. This equation is:

E(x) = (ax+b) mod m

E(x) = The…

E(x) = (ax+b) mod m

E(x) = The…

## Atbash Cipher

The Atbash Cipher is a monoalphabetic substitution cipher that is relatively simple and does not require a key. Instead of a key, the substitution simply relies on reversing the alphabet. Therefore, 'A' becomes 'Z', 'B' becomes 'Y', and so forth.…

## Caesar Cipher

The Caesar Cipher is one of the oldest ciphers, used by Julius Caesar to communicate with his generals. It works by shifting the alphabet down by a fixed number, or key. Due to the simplicity, it can be broken if the crypanalyst knows that a simple…

## Confederate Cipher Disk

The Confederate Cipher Disk was used in The American Civil War by the Confederate Army. Created by Francis LaBarre and based on the Vigenère Cipher, it consisted of two brass discs with the alphabet on each. As a mechanical cipher tool, it allowed…

## DES

The Data Encryption Standard (DES) is an outdated form of encryption that became vulnerable to brute-force attacks, and was replaced by AES. Developed by IBM in the 1970s, it was used by the U.S. government as their official Federal Information…
