Web1 Answer. You assume that T H → R H and H E → N I under the Hill cipher. The determinant of [ 19 7 7 4] is 19 ⋅ 4 − 7 ⋅ 7 = 1 ( mod 26), so the inverse exists and equals (using − 7 = 19 ( mod 26)) This allows us to compute the encryption matrix, and then the decryption matrix.

WebHill's cipher machine, from figure 4 of the patent In classical cryptography, the Hill cipheris a polygraphic substitution cipherbased on linear algebra. Invented by Lester S. Hillin 1929, it was the first polygraphic cipher in which it was practical (though barely) to operate on more than three symbols at once.
