QT QT GAME ENGINE DESIGN ASSIGNMENT 3 CODE

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)

21加密算法,用vB语言编写实现,可了解各种加密算法的结构(21, encryption algorithm, and realize vB languages, can understand the structure of a variety of encryption algorithms)

文件系统过滤驱动程序的框架，对于做文件透明加密的朋友很有帮助()

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.)

自己写的域天加密狗VB使用小例子，32位的加密狗快速开发源代码(Write your own domain days dongle VB use a small example, 32 dongle rapid development of source code)

SHA-256源代码，三个对外的函数：void SHA256Init (SHA256Context *sc) void SHA256Update (SHA256Context *sc, const void *data, uint32_t len) void SHA256Final (SHA256Context *sc, uint8_t hash[SHA256_HASH_SIZE]) 第一个函数初始化，第二个函数输入要hash的字符串，第三个函数输出结果(SHA-256 source code, three external function: void SHA256Init (SHA256Context* sc) void SHA256Update (SHA256Context* sc, const void* data, uint32_t len) void SHA256Final (SHA256Context* sc, uint8_t hash [SHA256_HASH_SIZE]) The first function is initialized, the second hash function, enter the string, the third function of output)

基于VB的M5数学密码算法源码,有需要的就下载吧。(VB-based M5 mathematical algorithm source code, there is a need to download it.)

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)

二进制文件操作工具 可以对二进制文件合并、分拆、加密、解密的工具，再对两个可执行文件进行合并后，显示第一个文件的信息，并且正常使用，第二个被忽略。(Binary file binary file manipulation tools can merge, split, encrypt, decrypt tool, and then the merger of two executable files, show the first file, and normal use, the second is ignored.)
