加密与解码――密码技术剖析与实战应用中的一个例子

对于密码学感兴趣的读者适合，当然要求一定的基础-for cryptography for interested readers, of course, requires a certain basis

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

 What is EAQUAL?     The intention of EAQUAL is to provide a objective quality measure for coded/ decoded audio      files. Currently the code is based on the ITU-R recommendation BS.1387.      EAQUAL will not supersede listening tests, but can be a useful tool to support listening tests,      categorize different coding algorithms and find bugs in algorithms. The more input files are      taken for the analysis, the better the results of EAQUAL will fit the reality.

twocrypt(2c)是一个 PoC工具，用于超狂妄者。它把两个文件加密成一个。不同的口令可以用于解译不同的变量。输出不能从单个加密文件中识别出来，并且这个工具使用一种合法的算法，这种算法本身并不意味着要隐藏任何信息。-twocrypt (2c) is a PoC tool, uses in the ultra arrogance. It encrypts two documents. The different password may use in the solution to translate the different variable. The output cannot from individually encrypt in the document to distinguish, and this tool uses one legitimate algorithm, this algorithm itself certainly did not mean must hide any information.

这个是DES加密算法源代码(C++语言类别)-This is the DES encryption algorithm source code (C++ language category)
