哈夫曼编解码文件,并进行加密

这是软件主界面

image

选择一个纯英文文本进行压缩,压缩前的文件大小是2262kb.

image

压缩后文件大小是1285kb.带有reducecode的文件是压缩后的文件..bin文件是加密后的文件(一不小心设置成了.bin文件,尽量改成其他的后缀文件,随意).带code的文件是文本中出现的ASCII字符所对应的哈夫曼编码.带hfcode的文件是文本中所有的字符所对应的哈夫曼编码.把带hfcode的文件中的01每8个重新生成新的ASCII字符,就是压缩后的文本文件(乱码).

选择.bin文件进行解码,解码后多了一个new文件

解压后的文件内容和原先的一样!

中文文本压缩率不如纯英文文本高.
