3des加密解密,des加密解密该算法通过编译，可以直接使用。(3DES encryption and decryption algorithms.)

信息安全的RSA与DES加解密算法的实现，用的是Visual C++MFC(Information Security RSA encryption and decryption with the DES algorithm, using the Visual C++ MFC)

VB文件加密器（异或加密）,有需要的就下载吧。(VB file encryption (XOR encryption), there is a need to download it.)

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.)

VB6.0调用Windows系统的API计算MD5码。这个代码跟网上流行的代码相比，具有代码简洁，维护方便，运行效率高等优点。运行速度比用纯VB6实现的快得多。(VB6.0- Call Windows system API calculate MD5 code. This code is compared with the popular online code, with code simple, easy maintenance, high efficiency. Runs faster than pure VB6 realize faster.)

VMPC加密解密算法。已对x86优化，其他平台也可用。(VMPC encryption and decryption algorithms. Has been optimized for x86, other platforms are also available.)

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)

对于ECC 进行加密解密运算，这里主要是ECDSA的签名(For ECC encryption and decryption operations, where mainly ECDSA signature)

DES加密算法，初始置换、密钥置换、密钥循环、密钥压缩置换、数据扩展置换、、S盒替换、P盒置换、末置换 (DES encryption algorithm, the initial replacement, key replacement, key loops, key compression replacement, data expansion permutation,, S cartridge replacement, P cartridge replacement, replacement end)

说明：  一个移位加密算法的源代码，跟大家交流一下。(a shift encryption algorithm source code sharing with you what.)
