ADFGVX Cipher

Keyword
In cryptography, the ADFGVX cipher was a manually applied field cipher used by the Imperial German Army during World War I. It was used to transmit messages secretly using wireless telegraphy. ADFGVX was in fact an extension of an earlier cipher called ADFGX which was first used on 1 March 1918 on the German Western Front. ADFGVX was applied from 1 June 1918 on both the Western Front and Eastern Front.
The cipher is named after the 6 possible letters used in the ciphertext: A, D, F, G, V and X. The letters were chosen deliberately because they are very different from one another in the Morse code. That reduced the possibility of operator error. [Wikipedia]

ADFGX Cipher
The ADFGX Cipher is a fractionating transposition cipher which combined a modified Polybius square with a single columnar transposition. It is closely related to the ADFGVX Cipher.
Affine Cipher
Affine Cipher is a type of monoalphabetic substitution cipher. It encrypts a text using an affine function (f(x) = ax + b).
Autokey Cipher
Autokey Cipher is a polyalphabetic substitution cipher. It is closely related to the Vigenere cipher, but uses a different method of generating the key.
Caesar Cipher
Caesar Cipher, also known as Shift Cipher, or Caesar Shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet.
