从一个随机文件读取256字节数据形成数据区DArea，再应用洗牌法所给的方法生成0~255的一个全排列DTab。试分别写出"求DArea中全部数据经 （1）以DTab为S-盒； （2）以DTab为P置换 -from a random file read 256 byte data area DArea form data, re-shuffling in law application to the formation of 0 ~ 255 DTab a full array. Try to write were "seeking DArea by which all data (1) DTab S-boxes; (2) DTab replacement for the P

一个x264编码的可执行程序 x264.exe，因为我只修改了 x264 的算法，未加入任何汇编，也没有修改x264的接口和功能，所以原版 x264 能运行的平台，此程序也应当能运行，且功能及调用方式不变。 执行命令方式为： -o 输出文件 输入文件 宽x高 -B 目标码率-X264 encoding an executable program x264.exe, because I only modified x264 algorithms, not to join any compilation, there is no modification of the interface and functionality of x264, the x264 can run the original platform, this procedure should also be able to run, and function and calls the same way. For the implementation of the order:-o output file input file width x high-B target rate

本文介绍了在JAVA环境下如何实现IDEA对称加密算法。由于电子商务和电子政务的普及，安全加密技术在其中应用非常广泛，对安全加密技术的要求也很高。目前在JAVA环境下实现IDEA加密具有很多的优势，因为JAVA是基于面向对象的编程语言,并且由于它的平台无关性能被大量应用于Internet的开发。-This paper presents the Java environment IDEA how to achieve symmetric encryption algorithm. As e-commerce and e-government popular, security encryption technology, which is widely used for security encryption technology requirements is also high. In Java environment under IDEA encryption has many advantages, because Java is based on object-oriented programming language, and because it is platform independent performance was widely used in Internet development.
