以C++语言在微机上实现了美国数据加密标准DES。可随微机软盘任意路径下的任何文件，加密，加密文件可在软、硬盘任何目录下或在网络中传送；另一方面可对软、硬盘中的任何文件进行解密，解密后的文件除在末尾多出几个空格符外与原文件完全相同，绝不影响EXE文件，COM文件或数据库文件的使用。密钥有加密者在键盘输入8个字符。(In c++ language microcomputer to U.S. data encryption standard DES. With the computer floppy disk arbitrary path of any of the files, encryption, encrypt files can be in soft, hard disk any directory or in the network transmission On the other hand, soft, hard disk to the any classify documents, the decrypted file in the end in a few more the space appears with the original documents are all the same, never affect EXE file, COM file or database files use. Key there are JiaMiZhe in keyboard input 8 characters. )

将天骄2服务端的加密文本文件与生成的软件放在同一目录下,点击批量转换, 完成后会在同目录下生成一个名为temp的文件夹,其中存放的就是转换后的文件. 因为加密和解密的规则完全相同,所以加密过程和解密过程相同, 也就是说如果原来的文件存放的是原文,转换后就会生成密文,如果原来是密文,转换后生成原文. 适用于天骄2,凤舞天骄的所有版本服务端.(The the Tianjiao 2 server encrypted text file in the same directory with the generated software, click on the batch conversion finished, it will generate a folder named temp in the same directory, which store the converted file encryption and decryption rules are identical, so the encryption and decryption process is the same, that is to say if the original file is stored in the original conversion will generate the ciphertext, if the original ciphertext, conversion generated text. apply to tianjiao, all of Fung Mo tianjiao, the version of the server.)

说明：  采用RCS做文件加密的源程序代码，VC环境。包含两个文件包，里面的Readme有详细介绍。(Using RCS to do file encryption source code, VC environment. Package consists of two documents, which detailed the Readme.)

实现对单文件的DES加密解密，不限制大小，DES加密部分自写，非调用，用于学习DES原理。(The realization of the single document DES encryption and decryption, no limit to the size, DES encryption part self written, non call, for learning DES principle.)

说明：  获取硬盘物理序列号,用来对软件加密，vs2008工程。(HD number)

RSA算法，主要讲述算法的原理和过程，设计到加密解密，和溢出处理，初级学习RSA用(RSA algorithm, the algorithm mainly about the principle and process design to the encryption and decryption, and overflow processing, the primary study used RSA)

仿射密码体制加解密，较移位代换等加解密体制，更加优越。(Affine cipher encryption and decryption, a shift substitution and encryption and decryption system, more superior.)

用VC++开发的一款MFC程序，能很好地实现RSA加密和解密算法，对学习RSA加解密算法很有帮助(MFC with VC++ developed a program that can well realize RSA encryption and decryption algorithms, RSA encryption and decryption algorithms for learning helpful)

说明：  用visual c++ 写的des加密算法演示 (with visual c write des encryption algorithm demo)
