Keyoxide verifies online identity with cryptography.

Once you have a PGP key pair, there are two ways to set identity.

1. Annotate your OpenPGP profile (public key) with “proofs”. (Uploading this to their server creates a profile page. (My Keyoxide profile page.))
2. Sign a Signature Profile (text file) with “proofs”. (You can send this to people. Not super useful yet.)

For each location you want to prove, you have to do two things:

1. Add some proof at the site. Like a Gist with proof text at Github, or a TXT record with proof text in a DNS entry.
2. Point to the above proof with an Identity Claim in the signature profile (text file) or OpenPGP profile.

Create a Keyoxide profile by uploading an annotated key to keys.openpgp.org.

$ gpg --edit-key MYKEYFINGERPRINT
...
gpg> showpref  # lists current notations
...
     Notations: proof@ariadne.id=dns:dblu.me?type=TXT
                proof@ariadne.id=https://mastodon.social/@dblume
                proof@ariadne.id=https://gist.github.com/dblume/19738ca4ba998f2f784904190a1a22ea
                proof@ariadne.id=dns:dlma.com?type=TXT
gpg> notation
Enter the notation:proof@ariadne.id=dns:mynewdomain.com?type=TXT
gpg> save

gpg --armor --output public.asc --export MYKEYFINGERPRINT

go to https://keys.openpgp.org/upload and upload the public.asc you have created in the code above.

Add/Remove/Edit an annotation in your public key.

gpg --keyserver hkps://keys.openpgp.org --send-keys MYKEYFINGERPRINT

(Again, not super useful yet.)

Starting with a text file with proofs in it:

mysignature.txt

See https://keyoxide.org/1CBD499C61C7A3A7DED3935F5E21C0D40ED9EB54
 
proof=https://mastodon.social/@dblume
proof=dns:dlma.com?type=TXT
proof=dns:dblu.me?type=TXT
proof=https://gist.github.com/dblume/19738ca4ba998f2f784904190a1a22ea

Sign it with gpg -u EMAIL_ADDRESS –clear-sign mysignature.txt, and get an asc file like:

mysignature.txt.asc
