It was the first practical polygraph substitution cipher in use. It was invented in 1854 by Charles Wheatstone, but named after lord Playfair after he promoted it heavily. Instead of encrypting single letters, the Playfair cipher encrypts pairs of letter (digrams or bigrams). church financial administrator duties

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.
