WebMar 11, 2024 · Gronsfeld - This operates very similar to a Vigenère cipher, but uses numbers instead of a key word. One Time Pad - A virtually uncrackable cipher that relies heavily upon a random source for an encryption key. Playfair - This cipher uses pairs of letters and a 5x5 grid to encode a message. It is fairly strong for a pencil and paper style … WebDigraph Substitution Ciphers are similar to Monoalphabetic Substitution Ciphers, except that instead of replacing individual letters in the plaintext, they replace pairs of letters with another pair of letters (or digraph). In …
