ssl implementation（delphi）-ssl implementation (delphi)

Encrypts/Decrypts a piece of text using vigenere algorithm.

这是一个静态的md4算法加密，是在vc++的环境中执行，c语言编写；(This is a static md4 encryption algorithm is the vc environment implementation, c languages;)

VB程序注册机范例，控件简单实用，采用流行且难以破解的算法加密机器码、序列号、注册码，能更好地保护您的软件(VB program RI example, the controls simple and practical, using the popular and difficult to machine code to crack the encryption algorithms, serial numbers, registration codes, can better protect your software)

说明：  数字签名的基础是公钥和私钥的非对称加密，发送者使用私钥加密消息摘要（签名），接收者使用公钥解密消息摘要以验证签名是否是某个人的。(The foundation of digital signature is asymmetric encryption of public key and private key. The sender encrypts message digest (signature) with private key, and the receiver decrypts message digest with public key to verify whether the signature is someone.)

这是我上信息安全课做的作业，des的加密算法。-This is my lesson to do on information security operations, des encryption algorithm.

RSA算法的实现，大家可以参考看看,用C实现-RSA algorithm, we can reference to see, using C to achieve
