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。-Based on DES and RSA algorithm for mixed-hybrid cryptosystem Cryptosystem full advantage of the public-key cryptosystem and symmetric cryptographic algorithm the advantages and overcome its shortcomings, every time you send updates to resolve the key issues.

Description: 1．问题描述
RSA密码系统可具体描述为：取两个大素数p和q，令n=pq,N=(p-1)(q-1),随机选择整数d,满足gcd(d,N)=1,ed=1 modN。

解密算法：D(c)=cd(modn)
2．基本要求
p,q,d,e参数选取合理，程序要求界面友好，自动化程度高。
