This server statically vends OpenPGP public keys for use with automatic key lookup. The web key directory mechanism is an alternative to public keyservers that allows consumers to verify the provenance of a key without having to establish a transitive web of trust.
For example, you can import my public key into reasonably recent
gnupg using the following command:
gpg --locate-key [email protected]
It should also work with any other compliant OpenPGP implementation.
