WebThese earlier cryptographic systems are also referred to as Ciphers. In general, a cipher is simply just a set of steps (an algorithm) for performing both an encryption, and the corresponding decryption. Caesar Cipher. It is a mono-alphabetic cipher wherein each letter of the plaintext is substituted by another letter to form the ciphertext.
