Homophonic Substitution Cipher is a substitution cipher in which single plaintext letters can be replaced by any of several different ciphertext letters. They are generally much more difficult to break than standard substitution ciphers.

Hill Cipher is a polygraphic substitution cipher based on linear algebra. Invented by Lester S. Hill in 1929, it was the first polygraphic cipher in which it was practical (though barely) to operate on more than three symbols at once. It used matrices and matrix multiplication to mix up the plaintext.

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.

ADFGVX Cipher
ADFGVX Cipher is a transposition and substitution cipher used during World War I by the German Army. The name "ADFGVX" comes from the six possible letters used in the cipher: A, D, F, G, V, and X.
