Description: 一种基于DES 和RSA 算法的混合密码系统
混合密码系统充分利用了公钥密码和对称密码算法的优点，克服其缺点，解决了每次传送更新密钥的问题。发送者自动生成对称密钥，用对称密钥按照DES 算法加密发送的信
息，将生成的密文连同用接受方的公钥按照RSA 算法加密后的对称密钥一起传送出去。收信者用其密钥按照RSA 算法解密被加密的密钥来得到对称密钥，并用它来按照DES 算法解密密文。

Sender automatically generated symmetric key, used in accordance with the DES algorithm for symmetric key encryption to send information, the generated ciphertext together with the use of the recipient in accordance with the RSA algorithm for public key encrypted symmetric key sent together. Who receive their keys in accordance with the RSA encryption algorithm decryption key was to get the symmetric key and use it in accordance with the DES algorithm to decrypt the ciphertext.
