Thanks a lot, but i have a part confuses me. Didn't DES has many keys? In each of the 16 rounds a different key was generated by DES, so as per my understanding its 16 keys. Now, how come in double DES we are talking about only 2 keys and 2 rounds only?!
Would you meant the initial key in DES became 2 initial keys in Double DES? And each key go in the 16 rounds? Please would you clarify my confusion here
