Concept for discussion: Replacing HTTP Signatures with Bearer Tokens for ActivityPub Federation

Curious what other people think about this idea. What if federation security was re-worked to use target-assigned bearer tokens to authenticate GET/POST requests? This would remove the need for complicated signing schemes and reduce system load under heavy traffic bursts (as no cryptography is required).

A basic implementation could look like this:

1. When instance A (a.example.com) first attempts to federate with instance B (b.example.com), a POST request is made to a dedicated registration endpoint. (for discussion, we'll say it's https://b.example.com/activity-pub/register-instance). This request includes fields necessary for verification, including the source domain name, target domain name, and a securely-generated verification token. Other metadata could be included to allow instance B to selectively allow/prohibit federation based on other criteria, but this is optional.
2. Instance B makes a POST request back to a dedicated verification endpoint on instance A (for discussion, we'll say it's https://a.example.com/activity-pub/verify-registration). This request must include the target domain name and verification token provided in step 2.
3. Instance A checks the verification token (and verify that it matches the target domain name) and return a successful value. The verification code must be invalidated after this call!
4. Instance B, after verifying instance A's request, returns a securely-generated federation key back to instance A. This federation key is a bearer token used to authenticate all requests from instance A to instance B. This key must be unique to instance A!
5. Instance A completes the original request with the Authorization header set to Bearer {federation_key}.
6. Instance B receives the request, detects the federation key, and checks it against the list of registered instances.
7. If the key does not exist or A has been defederated, then a 403 Forbidden error is returned.
8. If the key is expired or revoked, then 401 Unauthorized error is returned. Upon receiving a 401 error, instance A should start over from step 1 to re-authenticate and complete the request with a new token. This process should not be repeated for recursive failures!
9. If the key is approved, then a 200 OK response or 202 Accepted response is returned, and A can consider the request as successful.

Advantages versus HTTP Signatures:

• No cryptography requirements.
• Simple logic, no edge cases around HTTP query parameters or header order.
• Equally effective for all request types.
• Keys can be easily revoked or rotated.
• Supports authorized fetch and defederation use cases "by default".

Disadvantages versus HTTP Signatures:

• Breaks the actor model - instances are required as a first-class concept. (but really, the actor model is basically dead already. you can't even federate reliably without a WebFinger server, at minimum.)
• Requires multi-request "handshake" before communication. (but this is already required in practice, since a signature can't be validated without first requesting the signing actor.)
• Out-of-band protocol - communication can't happen over ActivityPub / ActivityStreams because this is a prerequisite to authenticate any request. (but again, we already require WebFinger and some software requires NodeInfo for full support.)

So, what are your thoughts? Good idea? Bad idea? Did I miss something? Please let me know, I welcome replies here!

Socialhome v0.22.0 released, with a completely new UI!

This is a massive milestone for the #Socialhome project, one that could not have been possible without the hard work of @alain@jase.social. If you have followed the Socialhome project, you'll know that Alain has been responsible for most of the development of project in the recent years. This includes rewriting the #federation library to ensure #ActivityPub support is first class. More recently Alain has taken the challenge of rewriting the frontend, which has fallen into a rather poor state over the years.

The new UI work is actually a coordination of two people working many years apart. Way back years ago @lightone@mastodon.xyz made some UI designs for a new Socialhome UI (thank you! <3). While the designs were not implemented for years, they were not forgotten. In 2023 Alain jumped to the challenge and started the full UI rewrite of the Socialhome frontend. This UI has now matured into a state that it is good for daily usage - which is the main focus of this release!

Currently, a Socialhome installation will still default to the old UI. If you do want to try out the new UI for example on socialhome.network, go to the account settings and toggle the "New UI" flag. Going back is also easy, should the new UI cause unforeseen issues (please do report!).

If you are a server admin, see the new UI installation instructions for how to add the new UI to your instance.

This is not all! The releases of v0.21.0 and v0.22.0 also contain a bunch of other changes and fixes. Most notably;

• ActivityPub profiles are now richer, including bio and a larger picture, in addition to an avatar.
• Many new API's to support the new UI, including session authentication, search, media upload, content fetching over uuid, profile organize and profile settings.
• Whoosh has been replaced with Xapian as a search index backend.

See the full changelogs. Additionally, the federation library has received a ton of changes and fixes which can be found here.

Also, last but not least, we moved from GitLab to Codeberg. Check out the new repositories.

Installing and updating

We recommend using the Docker images (amd64/arm64).

Notes on how to use the Docker images can be found in the docs.

What is Socialhome?

Socialhome is best described as a federated personal profile with social networking functionality. Users can create rich content using Markdown. All content can be pinned to the user profile and all content will federate to contacts in the federated social web. Federation happens using the ActivityPub and Diaspora protocols.

Please check the official site for more information about features. Naturally, the official site is a Socialhome profile itself.

This article is published on a website which is powered by BDServer. And I'm trying to make this website support ActivityPub, so you could for example, subscribe to me from your Mastodon account. Yet it is easier said than done.

Just built something I don't think any other fediverse project has: ultra-granular federation controls.

Loopers can pick exactly which servers to federate with, go local-only, or even pause delivery.

It was tough to code, but our community deserves this power ❤️
