Description: C# encryption and decryption procedures and source code, encryption key two steps, first select the file, the second step into a randomly generated encryption key on the Key and IV, using the sender' s private key signature random key, use the recipient public key encryption secret keys and signatures, using random key encrypted data packet using the DES algorithm, MD5 summary generated-> use of sender' s private key signature decrypt the general process is as follows: decomposition of the session key encrypted ciphertext = " private key to decrypt the sender = " recipient of public key authentication =" Decomposition of the key, DES block decryption = " with an explicit timestamp =" MD5 summary generation, summary comparison = " Extraction verify timestamp =" be clear, the public key by the sender expressly Summary .
