DES Algorithm Teacher use animation to help you to understand how the DES algorithm work to encrypt data.
Enjoy with animation learning
Cover all the encryption phases
There is a full example that explain how the S-DES algorithm work step by step. And it is cover all phases and functions for key generation (Permuted 1 , Left shift(s) , Permutation/contraction ) and for plaintext processing (Initial permutation ,Expansion/permutation , XOR , Substitution/choice (S-box) , Permutation , XOR, final swap , Inverse initial permutation)
