将国密算法SM3, SM4 ECB的C代码打包成dll库。 然后在C#中进行调用。 有输入输出接口，测试结果正确。 包含所有源代码，可在此基础上进一步开发(The C code of the Chinese national algorithm SM3, SM4 ECB is packaged into a dll library and then called in C# with input and output interfaces. The test result is correct. Contains all source code and can be further developed on this basis)

说明：  一个应用密码学的源代码，主要完成应用密码方面的功能。(a Cryptographic Application source code, application code to complete the function.)

Elgamal数字签名的一个大体验证,用于对一个文件的签名后在进行认证.一个VC开发的小程序.(Elgamal digital signature verification of a general for the signature of a document during the certification after. A small VC development process.)

快速取模指数算法，C++编写，下载即可编译运行，RSA算法里面需要用到的(Take the fast modular exponentiation algorithm, C++ to prepare, you can compile and run the download, the RSA algorithm which need)

该程序使用C++写的一个基于递归子程序算法的语法翻译器，是在vs2012环境下编写的，供大家参考和学习(The program uses C++ to write an algorithm based on recursive subroutine syntax interpreter is written in vs2012 environment, for your reference and learning)

实现对单文件的DES加密解密，不限制大小，DES加密部分自写，非调用，用于学习DES原理。(The realization of the single document DES encryption and decryption, no limit to the size, DES encryption part self written, non call, for learning DES principle.)

windows登陆密码信息拦截，获取明文口令。程序对不同系统做了处理，在2000,2003,xp,vista上都可以截取， 在2000,2003,xp中，通过UNICODE_STRING.Length 的高8位取xor key,如果密码是编码过的，则通过ntdll.RtlRunDecodeUnicodeString解码， vista则通过AdvApi32.CredIsProtectedW判断密码是否编码过，解码用AdvApi32.CredUnprotectW。(The windows Password intercept, access to the plaintext password. Processing program on a different system in 2000, 2003, xp, vista can intercept, 2000,2003, xp UNICODE_STRING.Length high eight take xor key if the password is encoded by the ntdll.RtlRunDecodeUnicodeString decoding, vista, to judge by AdvApi32.CredIsProtectedW and password whether encoding, decoding AdvApi32.CredUnprotectW.)

PHP5.2 5.3 5.4等 zend加密代码解密(PHP5.2 5.3 5.4 Zend encryption code decryption)

DES加密的雪崩效应分析，按照作业要求做的。(DES encryption of the avalanche effect analysis, done in accordance with operational requirements.)
