Single substitution
https://en.wikipedia.org/wiki/Substitution_cipher#Simple_substitution
Substitution of single letters separately-simple substitution-can be demonstrated by writing out the alphabet in some order to represent the substitution. This is termed a substitution alphabet. The cipher alphabet may be shifted or reversed (creating the Caesar and Atbash ciphers, respectively) or scrambled in a more complex fashion, in which case it is called a mixed alphabet or deranged alphabet.
