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.
