  • Decentralized chat in javascript

    Jump

  • id like to make it clear that the app is using webrtc which requires IP addresses to be exchanged which could result in IP address being exposed when using the public peerjs-server (hosting your own is an option). this app is explicitly NOT for anonymous communication. it explicitly shares IP addresses and data sent/recieved from peers cannot be moderated. the app is using cryptographically random ID’s for profiles to make sure they are unguessable. the connection details have to explicitly be shared.

    the app is pretty experimental in how it works so there isnt any useful documentation on it apart from what is mentioned in the post. if you have questions, feel free to ask and i can try to explain the best i can.

    there may be details you are interested in, but the post is quite large. you can search in that that post about how i plan to deal with syncing between devices. the functionality is not working in the app at the moment.

    the data is persisted to browser storage, and unsent messages will be queued up when peers are not connected. similarly, the functionlity is not working at the moment.

    peer discovery can be a whole separate discussion. the app provides ways to exchange connection data with links and QR codes. it is important that the user shares this with peers they trust, the ID is otherwise cryptographically random. upon first connection asymetric encryption keys are created and used for every future connection (to prevent impersonation).

    Why are only parts opensource?

    the part that isnt open source is the aws-cdk repo im using for deploying to S3. the app is otherwise open source and i give the instructions to deploy on your own github-pages if you want.

    can you explain more about that licence?

  • your concerns are well placed. i am not a security expert and the project is not a mature enough for it to have a security professional take a look, so it shouldnt be considered secure or encrypted until someone reputable can verify it.

    i open sourced it so i could investigate getting security advice without a budget... but of course its pretty complex to do without a budget. so i'll settle with what feedback i can get.

  • its open souce but understandably complex to understand.

    im using a thin wrapper around browser-based cryptography functions. im using webpack 5 module federation to import that file at runtime.

    https://github.com/positive-intentions/cryptography/blob/staging/src/stories/components/Cryptography.tsx

    those functions are used to create a kind-of decentralised authentication as described here: https://positive-intentions.com/docs/research/authentication

    the app uses peerjs to send encrypted messages. i have the checkbox only for the user to confirm this is for testing purposes only. it is also worded throughout the docs that users should be responsible for what data they share. the app doesnt need any personal detail to work (ip address - as per requirement of webrtc). im all ears for ideas on a previous post: https://www.reddit.com/r/darknetplan/comments/16qw24o/on_my_decentralized_chat_app_i_want_some_kind_of/

    pardon my art skills. i drew it on my phone. i was going for a "whale". a simple logo was enough. i dont expect version 2 to be any better. as for the domain, it was cheap. i would like to do rebranding at some point but i dont know enough to make any time for it.
