在 Linux 中计算文件的 MD5 与 SHA1

galeki posted @ 2007年10月04日 05:56 in Bash 和它的朋友们 with tags hash sha1 md5 , 9277 阅读

MD5 与 SHA1 是当前最常用的两种哈希算法,主要用来检测下载文件的正确性,计算你下载文件的哈希值,如果和官方公布的哈希值相同,那么可以确定你的下载是正确的。

在 Linux 下如何计算这两种哈希值呢,基本上所有的 Linux 发行版都内置了这两个命令,比如要校检的文件命为 download.iso:

1. 计算文件的 MD5 - md5sum

 

# md5sum download.iso
b9555cc1915652237948e37ccc9c484e  download.iso

2. 计算文件的 SHA1 - sha1sum

 

 

# sha1sum download.iso
bb7d67fb5776c2854edf35ec4a585ff8adc3dbda  download.iso

如果你不喜欢命令行的话,也有图形界面下计算哈希值的工具,这里介绍一款,CalcCheckSum:

 

除了 MD5 和 SHA1 以外,CalcCheckSum 还可以计算多种哈希,并将结果一并显示。只不过 CalcCheckSum 是基于 KDE 的程序。
