[feature] GoToSocial as Keyoxide service provider

[tsmethurst]

We should investigate what is required to allow people to validate their profiles using Keyoxide.

Keyoxide is a privacy-friendly tool to create and verify decentralized online identities.

Just like passports for real life identities, Keyoxide can be used to verify the online identity of people to make sure one is interacting with whom they are supposed to be and not imposters. Unlike real life passports, Keyoxide works with online identities or "personas", meaning these identities can be anonymous and one can have multiple separate personas to protect their privacy, both online and in real life.

Keyoxide now supports unified ActivityPub verification, so GTS profiles could get verified in this way.

However, Keyoxide seems cannot federate with GTS right now, with their actor get denied by GTS due to "response username does not match input".

It seems that keyoxide is providing keyoxide.org as the username in the endpoint /users/keyoxide, which caused the mismatch. I've opened a post and an issue on their side.

Neat, thanks for investigating :)

Update: The issue has been fixed on their side, released with keyoxide 5.0 and available on the main instance keyoxide.org. Maybe we can go ahead and close this issue if there aren't any more questions :)

Here's an example of my account:
