WebThe Affine cipher is a special case of the more general monoalphabetic substitution cipher. The encryption function is as follows: $$ E(x) = (ax + b) \ \text{mod} \ m $$ where x is the index of the plaintext letter in the alphabet, a and b are the key, and m is the size of the alphabet (26 for the English alphabet).
