HideInfo
- 使用java编写的LSB图像信息隐藏算法演示程序,可以将任何符合大小限制的文件拆分为一个一个bit隐藏到非压缩bmp图像中。支持在隐藏前通过zip类对文件进行压缩-prepared by the use of LSB image information hidden algorithm demo program, can be any size restrictions with the document for a split hidden bit of a non-compressed bm

Base64
- Base64编码的思想是是采用64个基本的ASCII码字符对数据进行重新编码。它将需要编码的数据拆分成字节数组。以3个字节为一组。按顺序排列24 位数据,再把这24位数据分成4组,即每组6位。再在每组的的最高位前补两个0凑足一个字节。这样就把一个3字节为一组的数据重新编码成了4个字节。当所要编码的数据的字节数不是3的整倍数,也就是说在分组时最后一组不够3个字节。这时在最后一组填充1到2个0字节。并在最后编码完成后在结尾添加1到2个 “=”。 -The idea of ̴
