DES-complete

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. )

该程序使用C++写的一个基于递归子程序算法的语法翻译器，是在vs2012环境下编写的，供大家参考和学习(The program uses C++ to write an algorithm based on recursive subroutine syntax interpreter is written in vs2012 environment, for your reference and learning)

des和rsa的算法演示文档 (des and rsa algorithm presentation)

3des算法code,已经通过visual c++编译．比一重des算法更加可靠！(3DES algorithm code, has passed visual c++ Compiler. Than one algorithm more reliable re-des!)

sha256计算代码，非常好用的代码，大家可以用这个代码直接计算哈希值，sha256实现 依次执行 SHA256Init、 SHA256Update SHA256Final 三个函数即可得到sha256结果(sha256 sourse code，Is very usefull)

线性反馈移位寄存器LFSR生成随机序列的原理，序列密码的加密过程(Linear feedback shift register LFSR to generate random sequence of the principle of the encryption cipher)

IBE基于身份的加密系统的系统叁数程序，使用VC6.0开发(IBE identity-based encryption system of systems Triple the number of procedures, the use of VC6.0 Development)

说明：  混合加密系统，支持多种加密方式混合加密系统，支持多种加密方式(Hybrid encryption system)

C network programming this source is vectorcross

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)
