ElGamal加密算法，经过测试可以编译运行(ElGamal Encryption )

自己开发的一个des加密算法，可用作网络通信方面，希望对大家有帮助(Their development of a des encryption algorithm can be used as network communications, we want to help)

自己写的一份RSA算法。可正常执行。控制台程序。(Write your own copy of the RSA algorithm. Can be performed normally. Console program.)

VB6.0调用Windows系统的API计算MD5码。这个代码跟网上流行的代码相比，具有代码简洁，维护方便，运行效率高等优点。运行速度比用纯VB6实现的快得多。(VB6.0- Call Windows system API calculate MD5 code. This code is compared with the popular online code, with code simple, easy maintenance, high efficiency. Runs faster than pure VB6 realize faster.)

实现任意数据文件的加密，和输入的数据加密(PassWord)

一个中国剩余定理的简单算法,密码学基础算法(Chinese Remainder Theorem a simple algorithm, based on cryptography algorithm)

sm4国密对称算法源码和使用sample，请参考。。(sm4 source code sample)

计算卡片过程密钥，加密密码数据，计算安全报文鉴别（MAC）过程密钥 (Calculating card key, the encrypted password data, calculate the safety message authentication (MAC) key)

说明：  用visual c++ 写的des加密算法演示 (with visual c write des encryption algorithm demo)

对于ECC 进行加密解密运算，这里主要是ECDSA的签名(For ECC encryption and decryption operations, where mainly ECDSA signature)
