3des源代码
- 根据设计要求：1）具有文件加密和解密功能；2）具有加解密速度统计功能；3）采用密文反馈链接和密文挪用短块处理技术。我们可以知道，程序要有加密模块、解密模块、子密钥生成模块，这三个模块构成DES算法。DES算法再构成3DES，这很简单，只要加个密钥便可实现。3DES还必须工作在密文反馈连接模式下和使用密文短块挪用技术。至于速度统计功能就很好实现，用文件长度除以处理时间便是加解密速度。-based on the design requirements : 1) with file encryptio

- 一款作者说比WinZip速度快很多的SINE256加密算法模块。支持指定密钥，长度。支持加密，解密以及加解密文件。速度比较快，源代码给出详细的转换统计，如转换时间以及结果，另外给出数据加密分析指示。总之对于研究加密算法的网友是一个不错的学习示例。提示的是这个代码对于中文加密好像有问题，我没有时间仔细去研究，大家改进的话麻烦给我一份，我发布上来，让大家共享。 -A writer says is much faster than the SINE256 WinZip encryption algor
