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.

So … 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.
