rpm数字签名
在使用yum时,rpm –import ******* 后面跟的是公钥,系统会把公钥的信息导入到rpm数据库中,rpm用到公钥时不会从/etc/pki/rpm-gpg/下的文件中读取,即使把下面的文件全删除了也没事。
导入公钥
rpm–import RPM-GPG-KEY-CentOS-5
后想查询这个公钥,或者像查询系统导入了多少公钥,可以用这个命令
rpm -qa gpg*
执行结果如下
gpg-pubkey-e8562897-459f07a4
gpg-pubkey-e8562897-459f07a4
gpg-pubkey-e8562897-459f07a4
gpg-pubkey-e8562897-459f07a4
gpg-pubkey-e8562897-459f07a4
gpg-pubkey-e8562897-459f07a4
这说明我已经导入了6个公钥了,而且都是相同的。
怎样查询公钥的详细信息
rpm -qi gpg-pubkey-e8562897-459f07a4
执行结果如下
