Export/Import snap signature keys


We are using snap signature keys to create/sign ubuntu-core images and private snaps.

I see various topics on exporting these keys to a private Key Vault using gpg, but have not seen any snap specific commands to do so.

What is the most effective way to export/import registered snap keys?

I am generating them using the following:

$ snap create-key myKey
$ snapcraft register-key


Has anyone had luck with this?
