微软的CryptoAPI加密技术加密技术介绍…

A simple cpp program, that receives a file, does a bit-wise "not" for every character, and adds "not" to the extension. Repeated running does the same and removes the "not" from extension. This a "pseudo-encryption", but very useful to avoid automated filtering software. This way it is possible to send "exe" files (or anything else) without the emails being blocked... First - send the source code, have your (enlightened) recipient compile it, then send the "notted" file. The code is not very efficient though, I only had 30 minutes to invest... :)-A simple cpp program, that receives a file, does a bit-wise "not" for every character, and adds "not" to the extension.

对ORCLE数据库进行保护，具有很强的功能，有加密，访问，删除，等保护功能-right ORCLE database protection, and highly functional, encryption, access, deletion, such as the protection function

编程中获得会话密钥匙非常重要的 MSDN 展示了一种使用私钥的方法。 但是微软的这个在MSDN中例子相当的长。 本文下面介绍的这个方法不仅更快而且更有效 -Programming cryptographic key conversation was very important MSDN demonstrated a method of using the private key. But in Microsoft"s MSDN examples longer. Presented below is the method not only faster and more effectively

RSA资料全集是我在学习RSA时收集的资料，它对我学习这种算法有着极大的帮助，不知对大家有帮助没有，希望对大家学习密码学有所帮助。-All of the information of RSA was collected when i was studying RSA.It gives me a great deal of help though i don t know how about you.I wish it also give you some help about the cryptology.

Openssl的SSL证书认证程序，也是用VC写的。已通过测试。-Openssl SSL certificate authentication procedures, as well as with VC writes. Have passed the tests.
