密码安全方面的PGP资料,很有用的!是学习密码学的好东西@-PGP password security information, very useful! Is a good thing to learn cryptography @

DES加密算法的实现和演示，具体算法见网上，程序中有注释-DES encryption algorithm and demonstrate the achievement of the specific algorithm see online, proceedings have Notes

一个简单的ECC实现源代码，用C++编写，还包含文字说明-ECC realize a simple source code, using C++ Prepared, also contains text descriptions

MD5 加密算法 Delphi 源码。 编译为dll文件，方便其他语言的系统调用-MD5 encryption algorithm Delphi source. Dll file to compile and facilitate language system calls

本软件是根据DES加密算法，编成的应用程序。-software is based on the DES encryption algorithm into the application.

生成程序序列号在程序加密方面几好用-sequence generation process, the procedure uses encryption several areas

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.
