差分密码分析，此实验是对S-P密码体制的差分分析-differential cryptanalysis, the experiment of S-P Cryptosystem Differential Analysis

md5通用加密算法，采用C编写，也可以在C++下使用-General md5 encryption algorithm, using C to prepare, you can also use C++

双随相位加密系统的加密程序，调试好的，没有错误-4f

Simple steganography program written in Python. The program writes and reads information to/from 24 bits bitmaps.

应用密码学。学习密码学的最好资料.推荐-study cipher..........ph

代码详细的将DES算法的加密过程描述详细，通过MFC进行界面化操作，整体界面良好，具有很强的可读性和很好的独立性，突出了C++的封装型和继承性的有点，值得参考。。。。。。。。。。。。。。。。

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?
