Show HN: Seal – Open-source P2P encrypted chat in Rust and Tauri

Hey y'all, I've built a completely free open-source p2p Messanger in my free-time. Most 'private' messengers still rely on central server infrastructure to queue and hold messages in an inbox - that makes it a target for metadata or message collection.

With Seal there is NO Server-Side Inbox: Every Message directly travels from peer to peer via libp2p. Every Message is 'sealed' using Olm (1:1) and Megolm for groups via vodozemac The only server needed is a directory server, which purely acts asa short-lived adress lookup table

The Architecture is interesting too, your chat identity is an Ed25519/Curve25519 keypair generated locally, your public ID is simply the key fingerprint.

I'd love to hear your thoughts on the project.

I used Claude to help draft the initial code comments explaining the reasoning behind key architectural decisions, but I manually reviewed, audited, and corrected every single comment.
