Why does my gpg public key change after removing my master key (leaving just my subkeys) from the gpg key ring? I'm doing this so i can move my daily use keys (subkeys) to my online machine while leaving my master key completely offline. What i'm finding is that when i look at my public key (gpg --export -a firstname.lastname@example.org) with my master key present, the public key is completely different than it is after i remove the master key and just have the subkeys present. Why is this?
Here is the procedure i followed to remove the master key and leave just the subkeys:
$ gpg -a --export-secret-subkeys email@example.com > secret_subkeys.gpg $ gpg --delete-secret-keys firstname.lastname@example.org $ gpg --import secret_subkeys.gpg
