Since version 2.3.0 it is possible to store the keys in an SQLite database instead of the keyring.kbx file. This is in particular useful for large keyrings or if many instances of gpg and gpgsm may run concurrently. This is implemented using another daemon process, the "keyboxd". To enable the use of the keyboxd put the option "use-keyboxd" into the configuration file ~/.gnupg/common.conf or the global /etc/gnupg/common.conf. See also doc/examples/common.conf. Only public keys and X.509 certificates are managed by the keyboxd; private keys are still stored as separate files.
Note that there is no automatic migration; if the use-keyboxd option is enabled keys are not taken from pubring.kbx. To migrate existing keys to the keyboxd do this:
1. Disable the keyboxd (remove use-keyboxd from common.conf) 2. Export all public keys gpg --export --export-options backup > allkeys.gpg gpgsm --export --armor > allcerts.gpg 3. Enable the keyboxd (add use-keyboxd to common.conf) 4. Import all public keys gpg --import --import-options restore < allkeys.gpg gpgsm --import < allcerts.crt
