制作数字证书的程序，比较简单，便于理解，希望有所帮助(Making digital certificate procedure is relatively simple, easy to understand, I hope to help)

实现可以对任意文件进行RSA加密操作的窗体应用程序。经过加密的文件以及密钥文件都是文本文件。(Can realize arbitrary files on the RSA encryption operation of the application form. After the encrypted files as well as the key file is a text file.)

used for creating certificate and so on.

说明：  实现国密算法的SM2、SM3、SM4，可以界面上测试算法的正确性，同时包含国密局公开的国密算法规范，这是信息安全的基本软件。(Encryption algorithm to achieve the country s SM2, SM3, SM4, you can test the correctness of the algorithm interface and also includes the country close to the national Bureau of Public encryption algorithm specification, which is the basic information security software.)

实验名称：关于数组下标越界的异常操作。 实验要求：自定义String类，当数组下标越界调用异常处理。 初步认识：通过C++的异常处理建立在三个关键字try 、catch和throw实现。(Laboratory name: about array subscript bounds of abnormal operation. Experimental requirements: custom String class, when the array subscript transitions exception handling. Preliminary understanding: by c++ exception handling is based on three key words the try and catch and throw.)

国密接口的实现和测试案列 对程序开发员有很好的参考价值(SM2 interface function implement and test sample，valuable to program developer)

EtherCAT基础技术介绍，讲的比较易懂。。。(EtherCAT basis of technical presentations, talking about relatively straightforward. . .)
