Description: Implement a symmetric cryptographic technique
(1) In the single complete unit weight for a specific file DES encryption/decryption
(2) for the DES key characteristics (8 bytes, 64 bits, which really works for 56 bits), a mechanism designed to generate a secret key (ie, the key used for each session are temporary randomly generated)
