Deleting Public Keys from GPG and RPM key rings

In order to delete the public keys from the key ring, we would require the key_id. The key_id can be idenfied using the below steps using the file where the public key is stored.

To get the Key Details

gpg --throw-keyids < [Key-File-Absolute Path]

pub  1021D/1689B887 2005-03-11 ABC Company 
sub  1048f/47E5X96D 2005-03-11  [expires: 2015-03-09]

To get the Key-ID from the keyfile

key_id=${gpg --throw-keyids < [Key-File-Absolute Path] | head -1 |  awk {'print $2'} |  cut -d '/' -f2 |  tr [A-Z] [a-z]}


Delete from GPG keyring

gpg --delete-key  --yes $key_id

Delete from RPM keyring

rpm -e --allmatches gpg-pubkey-$key_id
