软件包签名校验

一、windows上校验

 

1、查看工具帮助

certutil -?

certutil -hashfile -?

 

2、校验md5、sha1、sha256

certutil -hashfile ubuntu-18.04.3-live-server-amd64.iso md5

certutil -hashfile ubuntu-18.04.3-live-server-amd64.iso sha1

certutil -hashfile ubuntu-18.04.3-live-server-amd64.iso sha256

certutil -hashfile ubuntu-18.04.3-live-server-amd64.iso sha512

 

二、linux上校验

 

md5sum      ubuntu-18.04.3-live-server-amd64.iso

sha1sum     ubuntu-18.04.3-live-server-amd64.iso

sha256sum   ubuntu-18.04.3-live-server-amd64.iso

sha512sum   ubuntu-18.04.3-live-server-amd64.iso

 

或者使用校验文件，下载到iso同一目录

wget http://releases.ubuntu.com/bionic/MD5SUMS

wget http://releases.ubuntu.com/bionic/SHA1SUMS

wget http://releases.ubuntu.com/bionic/SHA256SUMS

 

md5sum      -c MD5SUMS

sha1sum     -c SHA1SUMS

sha256sum   -c SHA256SUMS
