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

Undeniably believe that which you said. Your favorite justification appeared to
be on the internet the simplest thing to be aware of.
I say to you, I definitely get irked while people think about worries that they plainly do
