信息安全中的RSA算法，界面简单明了，功能齐全(information security of the RSA algorithm, simple interface, the full range of functions)

pdf文件加密移除小软件。使pdf文件可打印可注释。(To remove pdf file encryption. So files can be printed comments)

椭圆曲线加密算法，设置服务器一步的源代码(elliptic curve encryption algorithm, the step to set up the server source code)

这两个工程主要用CSP 1、CSPTEST 写的比较乱 主要是给当时一个朋友做参考调用的 完成非对称密钥的生成、导入、导出、加密、解密、对称的加密解密、签名、验证。 2、CSTTEST2 写的比前个好些，但是平时上班，下班自己也要写论文，所以花的时间也不太多，很多地方都偷懒了。比如文件大小我没有用NEW 而且指定了1024 有需要的朋友可以自己修改。这个工程主要是非对称的密钥的导出和导入，还有就是会话密钥的操作。(these two works mainly with a CSP. CSPTEST comparison was made mainly to the chaos when a friend called to refer to the completion of the non-symmetric key generation, importing and exporting, encryption, decryption, symmetric encryption and decryption, signature, the certification. 2, CSTTEST2 write better than in the previous months, but usually go to work and finish their own toilet paper so I spent the time is not too much, all of the lazy. For instance, file size I have not used the NEW 1024 and designated a need to amend their friends. The project mainly non-symmetric keys to the Export and Import, there is the session key operation.)

删除系统某存储区中的证书， 代码参考msdn(removal system of a storage area of the certificate, a code reference VARIANT)

编写的DES 对称加解密技术，可随时进行明文密文之间的转换，有需要的朋友可以下载测试！本人目的打算对后台数据库的敏感信息字段用该方法加密，然后用软件权限控制读取，这样即使直接SQL后台取数，也得不到明文数据。(Write DES symmetrical encryption technology, may at any time for conversion between plaintext cipher, friends in need can be download test! I purpose going to the backstage database of sensitive information field with the method of encryption, and then use software to read access control, so even if the SQL backend access directly, also can not get clear data. )
