DES

说明：  信息安全相关，经典加密算法A5，通过编译(Information security-related, classic encryption algorithm A5, through compiler)

用C/C++实现加解密算法及其应用：DES（或AES）和基于DES（或AES）的CMAC。(With C/C++ achieve encryption and decryption algorithm and its application: DES (or AES) and based on DES (or AES) of CMAC.)

空间后方交会，摄影测量学的重要程序，通过共线方程解算加密点，是摄影测量学的经典算法(Space Resection the photogrammetry important program through the collinear equation solver encryption point photogrammetry classical algorithm)

OpenSSL的RSA算法应用举例。是用VC写的，有实用价值。(RSA algorithm of OpenSSL is used and given an example. Written with VC, there is practical value. )

说明：  AES算法（即 Rijndael 算法）是一个对称分组密码算法。数据分组长度必须是 128 bits，使用的密钥长度为 128，192 或 256 bits。对于三种不同密钥长度的 AES 算法，分别称为“AES-128”、“AES-192”、“AES-256”。本文在分析了 AES 加密原理的基础上着重说明了算法实现的具体步骤，并用 C++ 实现了对文件的加密和解密。(AES algorithm (Rijndael algorithm) is a symmetric block cipher algorithm.The data packet length must be 128 bits and the key length used is 128,192 or 256 bits.For the three AES algorithms with different key lengths, they are called "aes-128", "aes-192", and "aes-256".In this paper, on the basis of analyzing the principle of AES encryption, the concrete steps of the algorithm are emphatically explained, and the encryption and decryption of files are realized by C++.)
