Weather radar echo generated for this code is its own no problem, I used

MD5Win-MD5文本密码生成-MD5Win-MD5 text password generation

由于BT老师的要求，非要将64位DES算法改编成16位的DES算法，小生在这里献丑了。-as teachers, add to the 64-bit DES algorithm adapted into 16 of the DES algorithm, Niche in a shortcoming here.

Openssl & ActivePerl-5.8 & 编译要点说明,按照说明很容易通过编译，本人已经测试过，祝你好运。-Openssl ActivePerl- Compiler 5.8 points that can easily follow the instructions through the compiler, I have tested, I wish you the best of luck.

锁住/解锁硬盘 - Locks in/the solution to lock the hard disk

这是一个好用的MD5的C++类；这个类可以加在控制台 程序中也可用在MFC中， 并且提供了详细的错误处理 函数，是一个安全的类。例程是一个MD5的MFC程序， 支持字符串和文件两种输入。-This is an easy to use the MD5 of the C++ Category this category can be added to the console program can also be used in MFC, and it provides a detailed error handling function, is a safe type. MD5 is a routine procedure of MFC to support the two input strings and documents.

利用Rijndael算法进行任意文件的加密。把任意一个文件分成N个16字节组，最后一组若不足16字节可以用空格去补！-Rijndael algorithm using arbitrary file encryption. To arbitrary N of a document is divided into 16-byte groups, and finally a group of less than 16 bytes can be used to fill space!

The Cryptography API: Next Generation(CNG) is a new and agile framework in Windows Vista, which implements an extensible provider model that allows you to load a provider by specifying the required cryptographic algorithm rather than having to hardcode a specific provider. -The Cryptography API: Next Generation (CNG) is a new and agile framework in Windows Vista, which implements an extensible provider model that allows you to load a provider by specifying the required cryptographic algorithm rather than having to hardcode a specific provider.

QR 码 （从快速响应代码缩写） 是一类矩阵条码商标（或二维条码） 设计为在日本汽车行业的第一次。条码是机器可读的光学标签包含有关它所附加到的项目信息。QR 码使用四个标准化编码模式 （数字、 字母数字、 字节 / 二进制和日文汉字）为了高效地存储数据 ；此外可以使用扩展。

MD5计算,可以将文件提取出摘要，进行比对，校验，实现指纹算法-MD5, can be extracted document summaries, compare and testing to achieve fingerprint algorithm
