I would like to automate a GPG private key export so it runs without user interaction.
gpg --export-secret-keys my@email.com
I tried providing --batch --passphrase-fd 0
arguments both with passphrase being passsed as:
--passphrase 'my-passhrase'
echo 'my-passphrase' | gpg ...
It didn't work. Is it even possible to export private keys without user interaction?
You should add --pinentry-mode=loopback
parameter, as well as --batch
.
Full example from the RNP CLI tests suite:
gpg --batch --homedir .gpg --pinentry-mode=loopback --yes --passphrase "password" --output keyfile.asc --export-secret-key userid
