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.)

采用c++实现RC4加密解密算法，该代码可以加密解密任意格式的文件( U91C7 u758ccc_cn R U6587 u4EF6)

对txt文件的加密解密，采用c++编写。(The encryption and decryption of the txt file, using c ++.)

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. )

IBE基于身份的加密系统的身份提取程序，使用VC6.0开发，即把身份转换成椭圆曲线上的点(IBE identity-based encryption system of the identity of extraction procedures, using VC6.0 development, namely, the identity into a point on the elliptic curve)

程序采用当前最先进的Rijndael算法作为核心算法，带有可变块长和可变密钥长度的迭代块密码。块长和密钥长度可以分别指定成 128、192 或 256 位。多线程操作，保证加密时程序界面流畅，加密速度大约9M每秒。(Procedures using the most advanced as a core algorithm Rijndael algorithm with variable block length and variable key length of the iterative block password. Block length and key length can be specified as 128,192 or 256. Multi-threaded operation, to ensure smooth program interface encryption, encryption speed of about 9M per second.)
