welfare lottery 3D, projections, the software has shrunk. Is their half-year effort, delphi development, it is entirely possible commercialization of the software (value 10,000), Now it dedicated to the PUDN.com

用ASP实现基于数据库的网页加密-ASP web-based database encryption

这是用C编写的命令加密法算法，请大虾们指教。-This is prepared by using C commands encryption algorithm, please advise their shrimp.

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: 

一个Data Encryption Standard加密程序(DES encryption)

国密算法java实现，包含SM2椭圆曲线公钥密码算法等(Implementation of Java algorithm)

有理bezier曲线应用于图像加密的源代码（Matlab）(Rational Bezier curves used in image encryption source code (Matlab))

取代式密码的存在，已经超过2500年 以上，最早利 用的范例 是在西元600年 左右，内容是以颠倒的希伯來 文构成的。凯萨大帝（Julius Caesar）也曾经使用称为Caesar密码法。方法为将每个字母用其后的第三个字母來 取代。(Replace passwords existence, has more than 2,500 years or more, the first example is using a range of about the year 600 AD, the contents of the text is upside-down Heber future composition. Great Caesar (Julius Caesar) has also been known as the Caesar cipher using the method. Method is used then each letter is replaced by the third letter.)
