"You have studied Substitution and Permutation techniques to encrypt the plaintext. In permutation techniques, the position of plaintext letters is changes and the ciphertext and plaintext have a same number for each English letter. In this question, you are required to design your own cryptographic algorithms using Permutation techniques. After explaining your algorithm, encrypt the plaintext "An investment in knowledge always pays the best interest" using your algorithm"?
