Hello excuse me, I need that at the moment of writing a password only with letters it is passed to numbers as this page says "2.5: Application of Matrices in Cryptography - Mathematics LibreTexts" then it is multiplied by the matrix that the user writes and divided in 2x2 matrices. How can I do this?

Have you read the other chapters of that book and learned matrix multiplication yet?
