Signing keys

I have an OpenPGP certificate with a number of subkeys.

You can use it if you want to securely send me an encrypted email for whatever reason (my main email resides on a small commercial server and I trust the maintainer, so don't worry about Google reading your emails etc.)

That certificate also comes with a signing key, which you can use to verify if a message is really coming from me. Try it with the below text

P.S. I highly recommend using sequoia over GnuPG for a number of reasons

PGP signature example

Hash: SHA512

-----END PGP SIGNATURE-----
Hint:

Assuming you have saved my OpenPGP key in the same directory you are running sq or gpg under cert.asc and the message above in message.txt

Using sequoia:

$ sq verify --message message.txt --signer-file cert.asc

You can also import my signature and authenticate it and then verify the message using that, but where's the fun in spoiling how to do that :) (read the sequoia book)

Git keys

I had been using Github's provided noreply email (80592203+Oakchris1955@users.noreply.github.com) in the past before I bought my own domain. With this email, I used two keys: 650A69BC617C66457D73C8243631B382EAA64076, with which I signed commits from my main device, and 5A67015B0A94E3D45F0F3A731F99981CB7F591D6, with which I signed commits for a couple of programs I wrote from my Raspberry Pi. I don't use any of them anymore.

Recently, I've been signing commits with key 03295FC8DEA7F2C193F9E579267AFA8AA998E5D3, under the name Oakchris1955 and my email address.
