循环异或-XOR cycle

C++ 源代码实现 非对称算法（RSA）-C++ Source code to achieve asymmetric algorithms (RSA)

这是我的代码，我用 c 语言编写的库 gmp 结合时的代码。我在 Visual studio 2013 上进行编译。我的程序是计算值为公共密钥 n、 e、 秘密的关键 d 和后存储在文件的文本。该程序有 3 功能是计算，最后的工作会议，生成密钥并转到上一届会议。当用户选择退出程序的功能然后程序将退出。

密码学程序设计---仿设密码-password procedures designed fake password---

本书真实系统地介绍了密码学及该领域全面的参考文献。 全书共分四个部分，首先定义了密码学的多个术语，介绍了密码学的发展及背景，描述了密码学从简单到复杂的各种协议，详细讨论了密码技术，并在此基础上列举了如DES、IDEA、RSA、DSA等10多个算法以及多个应用实例，并提供了算法的源代代码清单。 全书内容广博权威，具有极大的实用价值。自出版以来，得到业内专家的高度赞誉，是致力于密码学研究的专业及非专业人员一本难得的好书。-This book introduces the real system and the field of cryptography comprehensive references. Book is divided into four parts, first of all define the term more than cryptography, introduced the development of cryptography and background, describes cryptography from the simple to the complex variety of the agreement, a detailed discussion of cryptographic techniques, and on this basis cited, such as DES, IDEA, RSA, DSA algorithm, as well as more than 10 examples of multiple applications and provides the algorithm source code on behalf of the list. Broad authority of the contents of the book, has great practical value. Self-publishing has been highly praised the industry experts, is dedicated to the study of cryptography professional and non-professional a rare book.

一解码程序，挺好的东东，不过是用汇编写的，希望能对大家有所帮助。其中还有一个是hcs系列芯片的接收程序。-a decoding procedure very well, the Eastern, but is the compilation was made in the hope that it can be helpful to everyone. Among them were a series of chips is hcs reception procedures.

KEELOQ_ENcode　简单的加密程序，可惜就是没有源代码。-KEELOQ_ENcode simple encryption program, but is not the source code.

用c++实现仿射密码，我是在DevC++中跑的，应该在VisualC++中也行-With c++ Achieve affine password, I was DevC++ In running, it should be in VisualC++ Also line

Diamond加密算法-A Diamond encrypt arithmetic

用VB做万象密码查询工具，这里用到几个常用的API函数：FindWindow，SendMessage，GetClassName，WindowFromPoint-Vientiane password to use VB to do query tool, used here in several commonly used API functions: FindWindow, SendMessage, GetClassName, WindowFromPoint
