Web Key Directory
Web Key Directory is a new key discovery scheme that allows discovering OpenPGP keys from e-mail addresses.
For example, when looking for a key for Joe.Doe@Example.ORG the key would be fetched from the following location:
https://example.org/.well-known/openpgpkey/hu/iy9q119eutrkn8s1mk4r39qejnbu3n5q

Configuration
Adding key to Web Key Directory requires calculating encoded hash of the name and exporting binary key to that location.
For example, given e-mail address test-wkd@metacode.biz:
$ gpg --list-keys --with-wkd test-wkd@metacode.biz
pub rsa2048/0x6BA55ED83ABAE1BB 2018-05-08 [SC] [expires: 2020-05-07]
Key fingerprint = 74EC 8D3D A82A 79DA A25D F10C 6BA5 5ED8 3ABA E1BB
uid [ultimate] Test WKD Key <test-wkd@metacode.biz>
4hg7tescnttreaouu4z1izeuuyibwww1@metacode.biz
sub rsa2048/0x3B5E7761615E2207 2018-05-08 [E] [expires: 2020-05-07]
The hash is 4hg7tescnttreaouu4z1izeuuyibwww1.
Exporting the key (gpg --export test-wkd@metacode.biz) and putting it on:
https://metacode.biz/.well-known/openpgpkey/hu/4hg7tescnttreaouu4z1izeuuyibwww1
will make it available to all applications using Web Key Directory.
