The determinant of the matrix we are inverting is ac - bd (mod 26) = 15*19 - 12*2 = 261 = 1 (mod 26). We also need to find the inverse of the determinant (1), which luckily in this case is 1 because 1 is its own inverse. dspviewer2 ダウンロードWebDec 4, 2024 · Hill cipher is a block cipher method and repetition won’t be cause weakness.
