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. WebK1 and K2 were both made using Keyed Vigenere ciphers. K3 used a double rotational transposition. K1, K2, and K3 are all supposed to lead up to K4. Most people believe this …
