c++的MD5类，简单好用，只需要包含进去，就能方便使用-c++ the MD5 class, easy-to-use, only need to include, we can facilitate the use of

为了在NS2上的一些安全仿真，我试着介绍一下RSA算法。这个算法对WSN, MANET, VANET, FRID, BANET以及任何关注包安全性和数字签名的系统都非常试用。

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

slrc632程序..网上绝对找不到.对RC632读TYPEB完整的程序包-procedures .. slrc632 absolutely can not find online. TYPEB of Reading RC632 complete package

是我设计的在DSB中隐藏语音的例子. 用ELANIX公司的SYSTEMVIEW打开运行. 其掩护信号和隐藏信号输入输出端均需设置语音源文件,比如自己录制的声音.-I designed the DSB concealed voice example. ELANIX company with the SYSTEMVI EW open operation. their cover and concealment signal input and output signals required to set up voice source, For example, recording their voices.

What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used(In VB - The same technique can be implemented in "c" also.) Program flow Explained * Open the File to be encrypted for Binary Access Read(Say Source File) * Open a temparory file where encrypted data is stored for Binary Access Write(Say Destination File) * Loop through the Source File Byte by Byte * For each byte read from the file, Complement the data. (Using Not operator (in C we have to use "~" operator) * Write Complemented Data to Destination File * Delete the Source File * Rename Destination file as Source File(Now Encryption is over) -What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used (In VB- The same technique can be implemented in
