Description: Digital Signature Algorithm, using RSA asymmetric cryptographic algorithm should be non-symmetric encryption algorithm. DES is a symmetric encryption algorithm, and can not be used as a digital signature algorithm. Symmetric encryption algorithm, encryption and decryption using the same key, so I can not guarantee complete confidentiality of the key (at least two people know the encryption and decryption), it can not only determine the encryption identity.
