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). 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. bited cc

WebJun 19, 2024 · 1 Answer Sorted by: 1 Assuming that 2 × 2 matrix is used, and the encryption starts from the first letter of the plaintext, the key can be found by just calculating the "encryption" with size of 4 plain- and cryptotext block. For example, for CONV → SQZH, it would go as follows: ( 2 14 13 21) ( a b c d) = ( 18 16 25 7) ( mod 26) WebThe 25 ways to cipher Caesar by itself: DBFTBS, ECGUCT, FDHVDU, GEIWEV, HFJXFW, IGKYGX, JHLZHY, KIMAIZ, LJNBJA, MKOCKB, NLPDLC, OMQEMD, PNRFNE, QOSGOF, RPTHPG, SQUIQH, TRVJRI, USWKSJ, VTXLTK, WUYMUL, XVZNVM, YWAOWN, ZXBPXO, AYCQYP, BZDRZQ How to write Caesar Cipher in pseudo-code?
