Exporting and importing GPG keys over SSH

pull-private.sh

ssh user@remote gpg --export-secret-key KeyId | gpg --allow-secret-key-import --import

pull-public.sh

# Based on key ID.
ssh user@remote gpg --export KeyId | gpg --import

# Based on key owner name.
ssh user@remote gpg --export -a KeyOwnerName | gpg --import

push-private.sh

gpg --export-secret-key KeyId | ssh user@remote gpg --allow-secret-key-import --import

push-public.sh

gpg --export KeyId | ssh user@remote gpg --import

Thanks! Any idea what error sending to agent: Inappropriate ioctl for device means when pushing public/private key?

I have not come across that. I'm sorry.

@Jacob-Stevens-Haas I also have this error. you must add the --batch parameter to the importing gpg. eg gpg --armor --export-secret-keys $KEY_ID | ssh aiden@10.0.4.46 gpg --allow-secret-key-import --import --batch gpg (GnuPG) 2.3.7

I ran into several problems, the following should solve them:

1. error sending to agent: No pinentry: just install pinentry package on target machine.
2. error sending to agent: No such file or directory: just like @aidenscott2016 said, need to add --batch parameter with --import together.
3. problem 2 still, run echo pinentry-mode loopback >> ~/.gnupg/gpg-agent.conf and restart gpg agent after gpgconf --kill gpg-agent should fix it.
