Decryption with Feistel cipher:-
Decryption with Feistel cipher is essentially the same as the encryption process.
Use the cipher text as input to the algorithm, but use the Subkeys Ki in reverse order.
That is, use Kn in the first round, Kn-1 in the second round, and so on until K1 is used in the last round.
This is a nice feature because it means we need not to implement two different algorithms, one for encryption and one for decryption.
