What is Hackers' Pub?

Hackers' Pub is a place for software engineers to share their knowledge and experience with each other. It's also an ActivityPub-enabled social network, so you can follow your favorite hackers in the fediverse and get their latest posts in your feed.

Looking for implementations with support! ๐Ÿ”

As mentioned in the Fedify announcement below, I've implemented RFC 9421 (HTTP Message Signatures) and need to verify its interoperability with other ActivityPub implementations.

The challenge is that most major ActivityPub projects don't seem to have full RFC 9421 implementations in production yet. If you're working on an ActivityPub project that:

  • has implemented RFC 9421 (even in a development branch)
  • is currently implementing it
  • has plans to implement it soon

Please reach out! I'd love to collaborate on interoperability testing to ensure our implementations work properly with each other before merging this into 's main branch.

Any leads or connections would be greatly appreciated! ๐Ÿ™

We're excited to announce that we've implemented RFC 9421 (HTTP Message Signatures) in , complete with our double-knocking mechanism to maintain backward compatibility with the draft cavage version.

This implementation includes both signature generation and verification, meaning is used when both sending and receiving activities. While we haven't merged the RFC 9421 implementation branch yet, we're currently conducting interoperability tests with development versions of Mastodon and other implementations. Once these tests confirm compatibility, we'll proceed with the merge.

As noted in the attached docs, although RFC 9421 is the final and official standard for HTTP Signatures, the draft cavage version remains widely used across the . Our double-knocking mechanism ensures maximum compatibility by trying the RFC 9421 version first, then falling back to draft cavage if needed.

Currently, we support RSA-PKCS-v1.5 key pairs for generating HTTP Message Signatures, with plans to expand to other signature types in future releases.

We look forward to contributing to a more standardized and secure fediverse!

HTTP Message Signatures

This API is available since Fedify 1.6.0.

RFC 9421, also known as HTTP Message Signatures, is the final revision of the HTTP Signatures specification. Although it is the official standard, it is not widely used in the fediverse yet. As of May 2025, major ActivityPub implementations, such as Mastodon, et al., still rely on the draft cavage version of HTTP Signatures for signing portable activities.

Fedify automatically signs activities with the sender's private key if the actor keys dispatcher is set and the actor has any RSA-PKCS#1-v1.5 key pair. If there are multiple key pairs, Fedify selects the first RSA-PKCS#1-v1.5 key pair among them.

NOTE

Although HTTP Message Signatures support other than RSA-PKCS#1-v1.5, Fedify currently supports only RSA-PKCS#1-v1.5 key pairs for generating HTTP Message Signatures. This limitation will be lifted in the future releases.Double-knocking HTTP Signatures

This API is available since Fedify 1.6.0.

As you read above, there are two revisions of HTTP Signatures: the draft cavage version and the RFC 9421 version. The draft cavage version is declared as obsolete, but it is still widely used in the fediverse, and many ActivityPub implementations still rely on it. On the other hand, the RFC 9421 version is the official standard, but it is not widely used yet.

To support both versions of HTTP Signatures, Fedify uses the double-knocking mechanism: trying one version, then falling back to another if rejected. If it's the first encounter with the recipient server, Fedify tries the RFC 9421 version first, and if it fails, it falls back to the draft cavage version. If the recipient server accepts the RFC 9421 version, Fedify remembers it and uses the RFC 9421 version for the next time. If the recipient server rejects the RFC 9421 version, Fedify falls back to the draft cavage version and remembers it for the next time.

Please reach out! I'd love to collaborate on interoperability testing to ensure our implementations work properly with each other before merging this into 's main branch.

Any leads or connections would be greatly appreciated! ๐Ÿ™

Das Silicon Valley hat sich mit Donald Trump verbรผndet. Fรผr Europa ist das die Gelegenheit, die Abhรคngigkeit von der US-Tech-Branche zu beenden und digital souverรคn zu werden.

Auf der zeigt der Tech-Kritiker und Podcast-Moderator Paris Marx (@parismarx), wie eine europรคische Tech-Entwicklung aussehen kรถnnte, bei der die ร–ffentlichkeit Vorrang vor Investor*innen hat.

Looking for implementations with support! ๐Ÿ”

As mentioned in the Fedify announcement below, I've implemented RFC 9421 (HTTP Message Signatures) and need to verify its interoperability with other ActivityPub implementations.

The challenge is that most major ActivityPub projects don't seem to have full RFC 9421 implementations in production yet. If you're working on an ActivityPub project that:

  • has implemented RFC 9421 (even in a development branch)
  • is currently implementing it
  • has plans to implement it soon

Please reach out! I'd love to collaborate on interoperability testing to ensure our implementations work properly with each other before merging this into 's main branch.

Any leads or connections would be greatly appreciated! ๐Ÿ™

My 25 years of palaeoart chronology...

Here's my 2023 Western Interior Seaway illustration, from DINOSAUR BEHAVIOUR, by Prof Benton (Princeton University Press). It features an Edmontosaurus carcass attracting attention from birds, pterosaurs, bony fish, sharks, marine reptiles, and ammonites.

I realize there's a lot of AI-skepticism on Mastodon, but I think it's important to track how AI is being used more widely. So I spoke to GitLab's head of Field CTOs Brian Wald about how enterprises are implementing AI technology. Among other things, we discussed whether IT departments allow , what types of AI enterprises are building, how the role is shifting to an architect-type role, and GitLab's own AI strategy. thenewstack.io/the-field-cto-v
