Quick GPG note where I may find it.

To create an Ed25519 key, or whatever will be the default version in the future as defined by your GPG version:

gpg2 --quick-gen-key address@domain.example future-default

Note the keyid and edit it

gpg2 --edit-key KEYID
adduid # here fill your name and details as asked no comments\*
1 # to select the uid the first command generated
deluid # to delete the uid which doesn't contain your name
save

** Comments are considered harmful https://debian-administration.org/users/dkg/weblog/97

Then you are ready to publish the public key however you generally publish it, preferably in multiple places from where some recognise revokation certificates if the time ever comes.

NOTE: You can extend the expiry time of an expired gpg signature by issuing the expire command in --edit-key and the key is valid again when the update is reimported to gpg keyrings by other people.

Keybase note: To publish the key keybase pgp select --multi (where multi is required for multiple PGP keys per account and to submit changes to it, keybase pgp update --all (where –all is again necessary only if you have multiple keys).

Claws-mail note that is somewhat related.

Debian: sudo apt install claws-mail claws-mail-address-keeper claws-mail-attach-warner claws-mail-gdata-plugin claws-mail-pgpinline claws-mail-pgpmime claws-mail-smime-plugin

Load plugins from Configuration (menu) –> Plugins –> Load, they are all somewhere in /usr/lib/x86_64-linux-gnu/claws-mail/plugins or similar path.

It wants to read ~/.signature which I have like:

Mikaela Suomalainen
https://mikaela.info/
69FF 455A 869F 9031 A691  E0F1 9939 2F62 BAE3 0723

My other hats have like:

Mikaela Suomalainen
position, where, wwwpage
email address
xxx xxx xxxx
C69C B030 AECD C8A4 2301  D6B8 DC18 9FE6 FA9B D685

Note the empty line in the end, as PGP/INLINE is the way to sign emails, it the PGP signature comes after it and in my opinion looks a bit cleaner with the signature ending to an empty line.

Setting up GPG WKD (Web Key Directory), mostly stripped/adjusted from https://keyserver.mattrude.com/guides/web-key-directory/

Requires a control over domain/.well-known and email under that domain.

1. cd into site root
2. mkdir -p .well-known/openpgpkey/hu
3. touch .well-known/openpgpkey/policy
4. gpg --list-keys --with-wkd <search-that-matches-your-key>
5. gpg --no-armor --export <YourKeyID> > .well-known/openpgpkey/hu/<YourWKD>
6. repeat 5. for +git address and similar if applicable
7. in Jekyll _config.yml ensure existence of include: [.well-known] if applicable.
8. deploy
9. test with gpg -v --auto-key-locate clear,wkd,nodefault --locate-key email@example.net

NOTE: The empty policy goes to the openpgpkey directory, not hu (I initially failed at this part)

NOTE: only one key/WKD/email.
