Cipher's k3

WebHere's an explanation to the four basic keying types, K1 - K4. In a K1 cipher the plaintext alphabet is mixed with a keyword or phrase but the ciphertext is the straight alphabet. In a K2 only the ciphertext alphabet is mixed. In a K3 both are mixed with the same key. In a K4 both are mixed, but with different keys. WebThanks to this exploration of the Caesar Cipher, we now understand the three key aspects of data encryption: Encryption: scrambling the data according to a secret key (in this case, the alphabet shift). Decryption: …
