代码说明:

  之前,我在一个项目开发过程中,涉及到了TripleDes的算法,在实现过程中,我也参考了论坛现有的关于3DES的代码,发现大部分的代码在算法的实现上不够严谨,或者小有偏差,特别是对3DES的两种模式:ECB,CBC都罕有涉及。此版本提供的TripleDes可以实现3DES在两种模式下的2key/3key的加、解密。在速度优化和内存控制上都做了优化。(Before, I in a project development process, involving the TripleDES algorithms, in the realization of the process, I also made reference to a forum on the existing 3DES code and found that most of the code in the algorithm for the realization of loosely, or small deviations, especially for 3DES of two modes: ECB, CBC are rarely involved. This version provided by TripleDES 3DES can be achieved in two modes of 2key/3key increases, decryption. Optimized in terms of speed and memory control are optimized.)

    务器端基于select I/O模型。为防止程序界面阻塞,有一个子线程用于不断接收socket并select其中的处理。客户端只有一个线程函数,不过其利用率很高,可用于远程目录交换,请求文件大小,创建若干线程来下载文件。文件传输有上传和下载,还有对等传输,这个项目中,传输文件具体指下载。 (side is based on the Treasury select I/O model. To prevent the program interface obstruction, a son threaded socket for receiving continuous and select which of treatment. Only one client thread function, but its high efficiency, long-distance directory can be used to exchange documents requested size, creating a number of threads to download files. Upload a file transfer and downloading, and the transmission of the project, specifically referring to transfer files downloaded.)
