针对32位MIPS微处理器中CLZ指令（对单个字高位连零进行计数）的实现电路，使用了类似于超前进位的逻辑结构。包含测试文档，以及Design Compile所用的环境和脚本。(The CLZ instruction counts the number of leading zeros in a word. The 32-bit word in the GPR rs is scanned from most-significant to least-significant bit.The number of leading zeros is counted and the result is written to the GPR rd. If all 32 bits are cleared in the GPR rs, the result written to the GPR rd is 32. )

使用迭代方程Xn+1=Asin2(Xn-XB)生成混沌序列{Xi}，需输入A和Xb值，不同的值产生不同的加密效果，但是仅在混沌区内的加密效果最好。在Microsoft Visual Studio .NET 2003上调试成功，用C++语言编写-use an iterative equation Xn Asin2 = (Xn- XB) generated chaotic sequence (Xi) need input A and isolate value, different values in different encryption effect, but only in the chaotic region of encryption is the best. In Microsoft Visual Studio.NET 2003 Debugger success C Language

在不改变access文件密码的情况下，直接查看密码，数据库内容一览无余哦！-Without changing the password access documents directly view the password, database content glance Oh!

通过调用openssl库进行aes加密，本程序已编译好了openssl，无需在进行编译！生成时请引用lib文件(By calling the openssl library aes encryption, the program has compiled the openssl, without making compilation! Please cite lib files generated)

说明：  采用位置变换算法的加密解密系统，可以被改写成dll文件，处理文字加密与解密尝试(Location transform algorithm using encryption and decryption system that can be rewritten as dll files, text encryption and decryption attempt to deal with)

.rar中包括两个文件MD5.cpp和MD5.h，在MD5的基础上改进让其支持Unicode的宽字符，可以对CString进行32位的加密，使用vs2010进行测试过，在解决方案“头文件”“源文件”分别使用添加“已有项”，将.h和.cpp文件加入工程，可能会有两三个警告，但不影响程序运行
