Figure 2illustrates asymmetric key cryptography, which is also knownas public key … WebAn affine cipher, (like a shift cipher), is an example of a substitution cipher: In encryption using a substitution cipher, each time a given letter occurs in the plaintext, it always is replaced by the same ciphertext letter. For example, the plaintext letter ‘e’ might be replaced by the ciphertext letter ‘K’ each time it occurs.
