Hill cipher encryption in c++
WebOct 1, 2024 · 2x2 Hill is a simple cipher based on linear algebra, see this link . This implementation follows the algorithm recipe at Crypto Corner here. Using the Code A single class, HillCipher, is implemented. It gets the cipher key string in the constructor and exposes the following methods: string encode ( string plain ) string decode ( string encoded ) WebK = (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". I know with other matrices, e.g. for the determinant there is usually a formula, such as: a x d - b x c However, for the Hill Cipher I am completely lost. I have done the following:
