## What is WKD/WKS?
|
||||
|
||||
Due to all the issues involved with the PGP key servers we're using today, GnuPG introduced a feature named [**Web Key
|
||||
Directory**][wkd] (WKD): Instead of searching for keys on the usual key servers, WKD is taking a **fully**
|
||||
Discovery**][wkd] (WKD): Instead of searching for keys on the usual key servers, WKD is taking a **fully**
|
||||
decentralized and federated approach, where each mail domain is responsible for hosting its users public keys on an
|
||||
HTTPS web directory. For example, in order to retrieve the key for `john.doe@example.org`, they key can be located at

### DANE DNS Setup
|
||||
|
||||
Apart from WKD, EasyWKS can also serve PGP keys using RFC7929 DNS records ("OPENPGPKEY" or "TYPE61" records). However,
|
||||
since EasyWKS does not implement DNSSEC signing, it cannot do this alone. The authoritative DNS server in EasyWKS only
|
||||
responds to AXFR zone transfer requests. In order for DANE lookups to work, the zones must be replicated (AXFR'd) by an
|
||||
authoritative secondary nameserver that signs the zones itself.
|
||||
|
||||
#### EasyWKS DNS Server
|
||||
|
||||
Configure EasyWKS to run the DNS server, e.g. using the following systemd unit:
|
||||
|
||||
```unit file (systemd)
|
||||
[Unit]
|
||||
Description=OpenPGP WKS for Human Beings - DANE DNS Server
|
||||
|
||||
[Service]
|
||||
Type=simple
|
||||
ExecStart=/path/to/easywks dnsd
|
||||
Restart=on-failure
|
||||
User=webkey
|
||||
Group=webkey
|
||||
WorkingDirectory=/var/lib/easywks
|
||||
|
||||
[Install]
|
||||
WantedBy=multi-user.target
|
||||
```
|
||||
|
||||
If you're using EasyWKS' DANE feature, it is highly recommended to configure the SOA and NS records for each domain
|
||||
you're serving. Generally you want to add NS records for all nameservers that will be serving your zone, and at least
|
||||
set the MNAME and RNAME components of the SOA record. You can also configure EasyWKS to provide zone update
|
||||
notifications whenever a key is modified:
|
||||
|
||||
```yaml
|
||||
domains:
|
||||
example.org:
|
||||
ns:
|
||||
- ns1.example.org.
|
||||
- ns2.example.org.
|
||||
- ns1.example.com.
|
||||
- ns2.example.com.
|
||||
notify:
|
||||
- "2001:db8::53@10053"
|
||||
soa:
|
||||
mname: ns1.example.org.
|
||||
rname: dnsadmin.example.org.
|
||||
refresh: 300
|
||||
retry: 60
|
||||
expire: 1209600
|
||||
minimal: 300
|
||||
```
|
||||
|
||||
#### Knot
|
||||
|
||||
Knot is an authoritative nameserver that supports signing a replicated zone by the secondary (replicating) nameserver.
|
||||
|
||||
To configure Knot to transfer the zone from EasyWKS, set up an EasyWKS remote and use it as the replication master for
|
||||
DANE zones. DNSSEC signing must be enabled as well. If you want Knot to be notified of zone changes, set up a notify
|
||||
ACL too:
|
||||
|
||||
```yaml
|
||||
|
||||
acl:
|
||||
- id: acl-easywks.example.org
|
||||
address: [::1]
|
||||
action: notify
|
||||
|
||||
remote:
|
||||
- id: remote-easywks.example.org
|
||||
address: [::1]@10053
|
||||
|
||||
zone:
|
||||
- domain: _openpgpkey.example.org
|
||||
master: remote-easywks.example.org
|
||||
acl: acl-easywks.example.org
|
||||
dnssec-signing: on
|
||||
dnssec-policy: ...
|
||||
```
|
||||
|
||||
## EasyWKS Client
|
||||
|
||||
The file `client.py` contains a self-contained WKS client, which
|
||||
prompts you for your email address and IMAP/SMTP/POP3 password, and
|
||||
then attempts to figure out the mail servers via common
|
||||
autoconfiguration methods. Afterwards it will attempt a WKS key submission:
|
||||
|
||||
```console?prompt=$,
|
||||
$ ./client.py
|
||||
Enter email: john.doe@example.org
|
||||
Chose A58D3221F8079F35FF084890505A563492A56583
|
||||

|
||||
Autoconfigured incoming server: imaps://john.doe@example.org@imap.example.org:993
|
||||

Hi there!
|
||||
|
||||
This is the EasyWKS system at example.org
|
||||
|
||||
Your key has been published to the Web Key Directory.
|
||||
You can test WKD key retrieval e.g. with:
|
||||
|
||||
gpg --auto-key-locate=wkd,nodefault --locate-key john.doe@example.org
|
||||
|
||||

## Manual Key Import
|
||||
|
||||
In addition to WKS, EasyWKS also provides a command line interface for
|
||||
importing keys from standard input. This feature is mainly intended
|
||||
to be used for technical email accounts where using WKS might prove to
|
||||
be difficult:
|
||||
|
||||
```console?prompt=$,
|
||||
$ cat pubkey.asc | easywks import
|
||||
Skipping foreign email john.doe@notmydepartment.org
|
||||
Imported key A58D3221F8079F35FF084890505A563492A56583 for email john.doe@example.org
