在一个exe文件后面加上一个节，并设置密码，运行的时候需要输入密码才可以执行-in an exe file, insert a section, and set the password, Operation of the need to enter the password before they can implement

The Cryptography API: Next Generation(CNG) is a new and agile framework in Windows Vista, which implements an extensible provider model that allows you to load a provider by specifying the required cryptographic algorithm rather than having to hardcode a specific provider. -The Cryptography API: Next Generation (CNG) is a new and agile framework in Windows Vista, which implements an extensible provider model that allows you to load a provider by specifying the required cryptographic algorithm rather than having to hardcode a specific provider.

这是一个古典加密算法。是最近自己编写的。-This is a classical encryption algorithm. Recently prepared themselves.

Twofish 采用128位数据块(128 bits lock)，128-192-256-bit 可变长度密钥。-using Twofish 128 blocks of data (128 bits lock) EliteConnect (TM) Universal-192-256-bit variable-length keys.

基于LSB的图像中数据加密隐藏算法程序 图像的组成无非是一些字符串或者一些字节组成的字符串，然而，每一个字节数据位的重要度并不是一样的，两个相邻字节往往只有低位是不一样的。例如：00100110和00100111代表了两个不同渐变度的红色，但是就人眼是分辨不出来的。最低有效位LSB算法，就是利用这一点，达到图像压缩，或者数字水印的功能。 信息隐藏,即将信息嵌入某些载体,而使信息窃取者注意不到信息的存在。由于人眼的视觉的冗余及图像文件本身的数据量很大,数字图像文件是信息隐藏很好的载体,将需要保密的信… 包括的文件有： findtext.m, hidetext.m, main.bmp, new2.bmp, message.txt, output.txt, gui.fig, new.bmp, gui.asv, gui.p, secret.bmp, read me.txt, screenshot.bmp, screenshot.jpg-err

防止用DeDe软件反编译delphi程序-preventing anti-software compiler delphi procedures

几个密码算法的源代码，不知道有了没有~~ 下的人多了就继续上传-Some source programs of encryption arithmetic.I don t know whether it is always existed or not.I will upload it if a lot of people have downloaded.

今天我们学习了des对称加密算法这是一个des算法的C++实现-This is a des !
