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. campground in myrtle beach

WebRecall that a number multiplied by its inverse equals 1. From basic arithmetic we know that: The inverse of a number A is 1/A since A * 1/A = 1 (e.g. the inverse of 5 is 1/5) All real numbers other than 0 have an inverse Multiplying a number by the inverse of A is equivalent to dividing by A (e.g. 10/5 is the same as 10* 1/5) Webmatrix is used to encrypt the messages, and its inverse is used to decrypt the encoded messages.
