SHA

CRC32哈希算法的C#版源码．采用的是动态生成码表的方法．-CRC32-hash algorithm in C# version of the source code. The code is dynamically generated table method.

写专属或加密程序。 程序应该采取作为输入由程序然后加密的文件名。 程序应该要求用户输入密钥，应该用于加密文件。 程序的输出应该进入一个文件以同一个文件名，但.ENC引伸。-Write an exclusive-OR encryption program. The program should take as input a filename that is then encrypted by the program. The program should ask the user to input an encryption key, which should be used to encrypt the file. The output of the program should go into a file with the same filename but a .ENC extension.

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

C++写的md5算法实现，喜欢的拿去吧，哈哈~-Writing C++ implementation of md5 algorithm, like take it, haha ~

vb写的rsa加密算法-vb wrote rsa encryption algorithm

从一个随机文件读取256字节数据形成数据区DArea，再应用洗牌法所给的方法生成0~255的一个全排列DTab。试分别写出"求DArea中全部数据经 （1）以DTab为S-盒； （2）以DTab为P置换 -from a random file read 256 byte data area DArea form data, re-shuffling in law application to the formation of 0 ~ 255 DTab a full array. Try to write were "seeking DArea by which all data (1) DTab S-boxes; (2) DTab replacement for the P

the code can be used to encrypt your folder.
