实现BASE64编码-achieve BASE64 encoding

md5的源代码，我下了源代码不过不知道怎么使用哦，请各位大哥多多指教呀！-md5 source code, I had the source code but do not know how to use Oh, please enlighten me a lot of big brother!

DES完全自己实现！能对输入字符串或者选定实现CBC，CFB-1,-8,-64等模式。算法自带有效率检测函数，运行结束显示系统效率。此源代码完全胜任课程设计，就算是毕业设计也只需进行一点改进。欢迎大家下载!-DES to achieve fully their own! Able to enter the selected string or the realization of CBC, CFB-1,-8,-64, such as model. Efficient detection algorithm own function, run the end of display system efficiency. This source code fully qualified for curriculum design, even if it is also just graduated from design to improve a little. Welcome you to download!

Diffie-Hellman算法源代码,比较好用,值得参考借鉴-Diffie-Hellman algorithm source code, useful comparison, it is also useful reference
