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.)
