WebThe Playfair cipher was invented in 1854 by Charles Wheatstone, but named after lord Playfair who heavily promoted the use of the cipher. It is a polygraphic substitution cipher, which encrypts pair of letters instead of single letters. This makes frequency analysis much more difficult, since there are around 600 combinations instead of 26.

Web— The multiplicative cipher is a special case of the Affine cipher where B is 0. — The Caesar cipher is a special case of the Affine cipher where A is 1 and B is the shift/offest. The affine cipher is itself a special case of the Hill cipher, which uses an invertible matrix, rather than a straight-line equation, to generate the substitution ... WebMar 25, 2024 · Hill Cipher is a cryptographic algorithm to encrypt and decrypt an alphabetic text. In this cipher, each letter is represented by a number (eg. A = 0, B = 1, C = 2). To encrypt a message, each block of n letters (considered as an n -component vector) is multiplied by an invertible n × n matrix, against modulus 26.

WebHill ciphers use modular and linear algebra to encrypt and decrypt messages. First, each letter of an alphabet is given a numerical value. Modular algebra is used to keep calculations within the range of values that represents letters. Any message can be converted into a matrix of numbers. Then this matrix is multiplied by a key matrix.
