Did you know?
In classical cryptography, the Hill cipher is a polygraphic substitution cipher based on linear algebra. Invented by Lester S. Hill in 1929, it was the first polygraphic cipher in which it was practical (though barely) to operate on more than three symbols at once.

For the Decryption part, initially the adjoint of the matrix is calculated using 'Sympy' library and using the 'adjugate' function.

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.
