VC实现的图像加密算法，采用Arnold变换，对于初涉信息安全的人员有一定参考价值-The algorithm of encrypted image completed in VC, applying the Arnold transform .It is valuable to people who will devote himself to infomation security

3des 加密,可以进行3des,des等其他基本加密算法-3des

Motivation - A simple DES core  - Fast and Small Version  - Open Source Compatibility I believe that the core complies to NIST-800-17. However, there has been no formal third party verification. The official NIST specification can be downloaded here: 800-17.pdf. For the Triple DES, the NIST reference is located here: 

A novel image encryption scheme based on substitution-permutation network and chaos

des算法的一种升级算法-an update algorithm

DES算法源代码，这是自己书写的源代码，里面采用了非常多的技巧来提高编解码的效率，研究算法和源码的朋友们，我书写的这个代码可以作为你们很好的参考。-DES algorithm source code, which is writing its own source code, which uses a lot of skills to improve the efficiency of the codec to study the algorithms and source of my friends, I am writing you this code can be used as a good reference.

Net框架由于拥有CLR提供的丰富库支持，只需很少的代码即可实现先前使用C等旧式语言很难实现的加密算法。本类实现一些常用机密算法，供参考。-Net framework, as they own CLR provides support for the rich, with little code can be used to achieve the old language, such as C is very difficult to achieve encryption algorithm. Realize some of the categories used confidential algorithm for information.
