The Web Key Directory is an experimental feature to retrieve a key via
https.  It is similar to OpenPGP DANE but also uses an encryption to
reveal less information about a key lookup.

For example the URI to lookup the key for Joe.Doe@Example.ORG is:

    https://example.org/.well-known/openpgpkey/
    hu/example.org/iy9q119eutrkn8s1mk4r39qejnbu3n5q

(line has been wrapped for rendering purposes).  The hash is a
z-Base-32 encoded SHA-1 hash of the mail address' local-part.  The
address wk@gnupg.org can be used for testing.
