If you're too afraid of mangling the last word, use something like 'Z'+(random chars). But I really would not use any predictable padding with such a cipher. crystal court shops atlantis bahamas

Invented by Lester Hill in 1929, this cipher uses matrices and matrix multiplication to mix up the … WebThe Affine cipher is a form of monoalphabetic substitution cipher. The translation alphabet is determined by mapping each letter through the formula (ax + b) mod m, where m is the number of letters in the alphabet and a and b are the secret keys of the cipher. To ensure that no two letters are mapped to the same letter, a and m must be coprime.

WebThe Playfair cipher is a classic form of polygraphic substitution cipher. It was the first practical polygraph substitution cipher in use. It was invented in 1854 by Charles Wheatstone, but named after lord Playfair after he promoted it heavily. Instead of encrypting single letters, the Playfair cipher encrypts pairs of letter (digrams or bigrams).
