How to create additional gpg keyring

tested with gpg (GnuPG) 2.0.26:

gpg --no-default-keyring --keyring trustedkeys.gpg --fingerprint

beginners' hint: you can use any filename not just trustedkeys.gpg.

it will say gpg: keyring ``</path>/.gnupg/trustedkeys.gpg' created

to use:

gpg --no-default-keyring --keyring trustedkeys.gpg <your-gpg-commands-here>

gpg --keyring pubring.gpg --export KEY > /tmp/exported.key
gpg --no-default-keyring --keyring=path/to/new-keyring.gpg --import /tmp/exported.key

If you want the keyring to also be used by GPG by default from then on, as you say, omit the --no-default-keyring switch.

Find more information in gpg(1) manual under --keyring option.

gpg --export KEY1 KEY2 > trustedkeys.gpg for public keys and:

gpg --export-secret-keys KEY1 KEY2 > trustedkeys.gpg for complete keys (including private part).

Where you can supply (partial) fingerprints for KEY1, KEY2 etc.
