无需工具软件,校验文件MD5、SHA1、SHA256值

原创:张荣国

刚有个朋友问我,他下载了个iso,看网上说要验证sha256值,但是上面说的工具软件,他网上没找到,问我能找到吗。

我听了笑笑的说,验证sha256值还要什么工具软件啊,直接命令行就行了。网上的还真是误导又浪费时间,要下载,要安装,还占用硬盘空间,真奇葩。

那么我说说怎么命令行查询文件MD5、SHA1、SHA256值

Windows 系统下校验文件的SHA256

打开 cmd 窗口,使用certutil命令即可校验文件MD5、SHA1、SHA256:

效验文件的MD5值,如:

在>后面输入: certutil -hashfile D:\windows10_2020.iso MD5

效验文件的sha1值,如:

在>后面输入: certutil -hashfile D:\windows10_2020.iso SHA1

效验文件的sha256值,如:

在>后面输入: certutil -hashfile D:\windows10_2020.iso SHA256

注意:检验时,如果文件比较大,请耐心等一下,完成后就会显示出文件的值,比如说sha256的值出来后,就可以跟原iso提供的sha256值对比了。完全一样,就放心。

Linux系统下校验文件的SHA256值

则使用 md5sum、sha1sum、sha256sum 命令计算文件的校验值;

效验文件的MD5值:

> md5sum ./linux2.tar.gz

效验文件的SHA1值,如:

> sha1sum ./linux2.tar.gz

效验文件的sha256值,如:

> sha256sum ./linux2.tar.gz

其中linux2.tar.gz是文件名
