密码编码和密码分析：原理与方法

非对称加密RSA的实现及其源代码-RSA asymmetric encryption and the realization of the source code

playfair的源代码，很简洁，跟网上现存的版本有所差异，但是效果是很不错的。-playfair source code is very simple, with the existing version of the web is different, but the effect is very good.

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.

CRC算法与C语言

这一个16位的CRC校验的源码，源码也已经很详细的注释过了-This is a 16-bit CRC checksum of the source code, source code also has very detailed notes after a

本代码是自己封装的MD5加密类，接口齐全，直接可以调用-This code is its own type of package MD5 encryption, interface complete, can be called directly

这本书包括了密码学和水印学竞争在内的各方面技术，这本书的内容覆盖知识范围广博，书中还有经过整理的代码，源代码等。-This book includes the study of cryptography and watermarking competition, including all aspects of technology, the content of this book cover a broad range of knowledge, the book also after finishing the code, source code and so on.

C++ implementaion for RSA together with the Wiener attack. It uses NTL library for big numbers

著名的l0pht代码！-famous l0pht code!

有些还是很有用的，网络验证经常能用到的，直接将cpp文件加入到工程里就可以了---Can realize analog keyboard, driver class. Like an ordinary keyboard can be used
