One of the challenges that I'm working on is empowering people with consumer-class internet access (i.e., dynamic addresses) to run their own Fediverse servers. The Publish/Publisher and websocket components I've added to #SofaPub move in that direction.

This allows someone with broad connectivity to re-publish connections from users who are more limited.

This is a big addition and I haven't published it to crates.io yet. But the code is at https://gitlab.com/justindthomas/sofapub.

#ActivityPub #Rust

In about 16 commands, I demonstrate installing #SofaPub, creating a new identity, responding to an external Follow request, sending a new Note ("Status" in Mastodon parlance), and then deleting everything from the remote server.

Everything in SofaPub is done from the command-line. I describe a couple of steps taken from the Serendipitous web interface to facilitate the interaction.

Network/DNS configuration (with TLS) is in place prior to this sequence.

#activitypub

@silverpill Thanks for the suggestion. I see a ton of Delete messages from Mastodon that seem to rely on the RsaSignature2017 signatures. Or maybe those are superfluous and they'll work with just the HTTP signature - I'll test that.

I've been spinning my wheels with JSON-LD and Rust, trying to figure out how to implement the RsaSignature2017 stuff captured here:

https://socialhub.activitypub.rocks/t/making-sense-of-rsasignature2017/347

None of the libraries I find (sophia, json-ld) seem to be complete enough to help. Am I missing something obvious? I really don't know anything about JSON-LD, and the learning curve seems very steep (and honestly, I'm not sure the pay-off is worth it).

Has anyone tackled this challenge?

#activitypub #rust

Successfully sent a message from my local #SofaPub server to myself at infosec.exchange. The command I used was:

cat ./hello_world.json | sofapub post https://infosec.exchange/inbox

The JSON file is just an ActivityPub Create message I created by hand in Emacs.

Also uploaded sofapub to crates.io. You can install it with `cargo install sofapub` and run the executable right away. I'll update the documentation shortly to align with that usage.

#Rust #ActivityPub

@silverpill I have the WASM code for that split off in the 'olm' folder at the GitLab organization. It could probably be reused for other projects.

The reason it's split off as its own module is that it requires x25519-dalek which in turn requires an old version of zeroize that doesn't play well with any reasonably modern version of the rsa crate I use for signing in the 'enigmatick_wasm' module.

@silverpill I have the beginning of a diagrammatic overview of the structs involved, but I need to spend more time writing up the details.

It's nothing particularly novel (as encryption really should not be). Just Olm with an ActivityPub overlay.

@fediforum I'm building a Fediverse server on Rust and Svelte with native end-to-end encryption built-in facilitated by wasm modules: https://gitlab.com/enigmatick

Still early, but ActivityPub works (I can receive and send posts, etc.) And the E2EE is framed out for 1:1 direct messages with a very basic UI implementation built.
