It's the Signal Protocol via libsignal, not handmade. Your message reaches the server the moment you send it, so logout never loses it and delivery doesn't depend on your session. The server only holds public keys and ciphertext, held 30 days for pickup. Each message is bound to the sender's identity key, so the recipient can confirm who sent it, verified by a safety number. Logout only wipes local keys, affecting old history on a new device. Key backup is planned.

In the browser, in IndexedDB (one store per account), kept encrypted with a non-extractable AES-GCM key, and wiped on logout. The server only ever sees public keys and encrypted messages, never private keys.

I saw below that you’re planning an FEP. I’d love to read what you’ve got, once it’s published 🙂

And yeah @all - we’ve talked about interior with Bonfire and Emissary. One thing at a time.. but that’ll be important once Mastodon joins the party next year.

Unfortunately not, but I am following what is being done 🙂

Would be awesome to make Loops compatible with this!

I vendored, not reimplemented. I use https://www.npmjs.com/package/@privacyresearch/libsignal-protocol-typescript, a pure TS port of libsignal running on Web Crypto. I only wired the sessions and the ActivityPub transport.

Thank you for your reply! 🙂
Did you reimplement the protocol or did you vendor libsignal?

I've written several posts recently with the tag, you should find all the details there.

Could you tell me, what the fedihood project is? Is there any website?
I tried to find more info, but I couldn't.

The Signal Protocol (i.e. the encryption itself) is an open, documented spec with open libraries (libsignal). I use the protocol, not Signal's API or servers.

I'm following what they're doing, though it works differently: they're going for MLS over ActivityPub, while I use the Signal Protocol. With HolosSocial I already had something working and published, so I just extended it to my other project. Once their approach is available, I even suggested switching to it.

Does Signal offer a stable API for third-party developers? Is it documented?

I reused the work I did on HolosSocial, which already used the Signal Protocol.
I'll write a FEP about it, since it works well.
