WebMar 25, 2024 · In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption —a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment. To encipher or encode is to convert information into cipher or code. In common parlance, “cipher” is synonymous with … WebI'm new to cryptography and I cannot seem to get my head around this problem: The problem says that the Hill Cipher using the below 2 x 2 key matrix (K) was used to produce the ciphered text "KCFL". K = (3 5) (2 3) It then asks to use the Hill Cipher to show the calculations and the plain text when I decipher the same encrypted message "KCFL".
