Encrypt the message “GTU EXAMINATION” using the hill cipheralgorithm with the key matrix 5 174 15

For a certain Hill Cipher the Encryption Matrix is [[17 17 5] [21 18 21] [2 2 19]]. The Plaintext is orb. The corresponding Cipher text will be

Write a program for Hill Cipher Method (Use 2 x 2 Matrix and 3 x 3Matrix)Note: (Optionsshould be given to user for Key matrix. it is either 2 x 2 matrix or 3 x 3 matrix)Hint: https://www.javatpoint.com/hill-cipher-program-in-javaBelow change is required in your submission:1. You have to take input as key matrix2. Entered matrix is square matrix or not, if not pls re-enter the matrix3.  Take input of plaintext is also in square matrix form for ex if 2 X 2 matrix is entered than plaintext should be 4 character, if matrix is 3X3 than plaintext should be 9 character like wise...Note: use padding if necessary
