一个简单加解密的小程序 (A simple encryption and decryption program)

本资料主要实现了文字图像的加解密，主要应用的算法有五种，分别是DES，AES，RSA，ECC，MD5，其中椭圆离散曲线加密算法较难。(This information is mainly to achieve the text image encryption and decryption, mainly used the algorithm has five, respectively is the DES, AES, RSA, ECC, MD5, which discrete elliptic curve encryption algorithm is more difficult.)

模拟 SKEY协议通信过程。SKEY身份认证解决方案，可以有效解决重放攻击。重放攻击是指攻击者通过某种方式在网络连接中获取他人的登陆账户与口令，然后利用它多某个网络资源的访问权限。而现在S/Key协议分配给访问者的口令每次都不同，所以，就可以有效解决口令泄漏问题。因此，可以避免重放攻击。(a simulation of SKEY protocol)
