    Decentralized anonymous blockchain messenger. Crypto In-Chat

  2. 2TP

    TerminalPhone is a single, self-contained Bash script that provides anonymous, end-to-end encrypted voice and text communication between two parties over the Tor network. It operates as a walkie-talkie: you record a voice message, and it is compressed, encrypted, and transmitted to the remote party as a single unit. You can also send encrypted text messages during a call. No server infrastructure, no accounts, no phone numbers. Your Tor hidden service .onion address is your identity.

    This is a project I made to learn more about crypto. I've also written a [post](https://vaktibabat.github.io/posts/ecurvechat/) that explains all the crypto concepts and algorithms used in the project, and how I implemented them. I'd be very glad for any feedback about both the code and the post :)

    Hello HN, I have been working on a desktop P2P messenger called Kiyeovo for the last ~8 months, and I just published its beta version. Quick backstory: It started out as a CLI application for my Graduate Thesis, where I tried to make the most secure and private messenger application possible. Then, I transformed it into a desktop application, gave it "clearnet" support and added a bunch of features. Short summary: The app runs in 2 completely isolated modes: - fast mode: relay/DCUtR -> lower latency, calls support - anonymous mode: Tor message routing -> slower, anonymous These modes…

    Hey HN, I've been playing around with OpenPGP.js and Soketi lately and decided to build a simple E2E encrypted messaging app. It's called subtle.sh. The idea is pretty straightforward: you need to send a secret to someone, but you don't want to use Slack, email, or any other plain text medium. subtle.sh generates a fresh session with ephemeral keys, you share the link, and once the tab is closed, everything disappears. Some key points: - Zero setup required (no accounts, no installation) - E2E encryption using OpenPGP.js - Real-time messaging with Soketi (an open-source Pusher alternative) -…
