can u help me plz :yawn: to solve this :


Write a program for data encryption using Double Transposition technique. Your
program should encrypt any plaintext given a secret key. The inputs to your
program are: (1) plaintext stored in a file, (2) secret key which refers to the
matrix size and permutation. Note that you need to restrict the matrix size to be
at least 4x4. For matrix size smaller than 4x4, the user has to be notified by a
message indicating the problem of such small size. The output of your program
is the ciphertext stored in a file labeled by “Ciphertext”.

and the Double Transposition technique theory
