说明：  配置 miracl 库，熟练调用 miracl 函数库，特别是其中的椭圆曲线运算相关函数对大数进行运算。学习并掌握 SM2 椭圆曲线公钥密码算法，开发 C 语言程序实现对消息的 SM2 加密和解密。(Configure the miracl library, skillfully call the miracl function library, especially the elliptic curve operation related functions to operate on large numbers. Learn and master SM2 elliptic curve public key cryptography algorithm, develop C language program to realize SM2 encryption and decryption of messages.)

说明：  基于MD5的文件完整性检测程序，共包含4个文件：md5.h、md5.cpp、test.cpp、nankai.txt。编译：命令行模式下，切换到代码所在目录，输入make后回车即可。(The file integrity testing program based on MD5 contains 4 files: md5.h, md5.cpp, test.cpp, nankai.txt. Compile: In the command line mode, switch to the directory where the code is located, enter make, and press Enter.)

数据加密的工具源代码--Source code of data encryption tool

RC3算法，用c语言实现。包括加密和解密(The RC3 algorithm using the C language. Including encryption and decryption)

一种比较简单的加密方法，存成Form1.frm,就可以打开了(This is a simple encryption algorithm)

这个是对文件进行加解密的项目，提供一些库函数，你可以直接调用(this source code s function is to encrypt and decrypt the file ,so ,of course ,it can speed up your program)

delphi6写的CRC32的加密算法。 另有付加例子程序-Delphi6 CRC wrote the encryption algorithm. Another example of pay increase procedures
