这个小软件通过在可执行文件(.exe)的尾部添加一个新节(Section)，并且修改PE的入口地址，使可执行文件在运行时，跳出一个输入密码的对话框，从而实现了简单的加密。-small software in executable files (. Exe) to the tail adding a new section (Section), and amend the PE import addresses, so that the executable file is run, jump out of a password dialog box, thus achieving a simple encryption.

RSA加密实现，希望对大家有所帮助，研究算法是很让人痛苦的事情，大家多多努力-RSA encryption realize, I hope to be helpful to everyone to study the algorithm is a very painful thing, a lot of U.S. efforts

des的变形算法，很有用的-des deformation algorithm, a very useful

常用的密码算法，如RSA，MD2，MD5等，还包括简单的例程，很久以前写着玩的-commonly used cryptographic algorithms, such as RSA, MD2, MD5, also includes a simple routine, a long time ago wrote a play

在Visual C++ 6.0下利用Rijndael算法进行任意文件加密，一个rijndael加密算法的使用实例，虽然图形界面做得比较粗糙，但是程序本身有很多值得参考和学习的地方- 6.0 carries on the free document encryption in Visual C using the Rijndael algorithm, a rijndael encryption algorithm use example, although the graphical interface does quite roughly, but procedure itself has the very multiple-valued reference and the study place

这是一个好用的MD5的C++类；这个类可以加在控制台 程序中也可用在MFC中， 并且提供了详细的错误处理 函数，是一个安全的类。例程是一个MD5的MFC程序， 支持字符串和文件两种输入-This is an easy to use the MD5 of the C++ category this category can be added to the console program can also be used in the MFC and to provide a detailed error handling function, is a type of security. MD5 is a routine procedure of MFC, and documentation to support two types of input string
