SecureBit

What it does

Since our last launch, SecureBit.chat has grown from a web-only P2P messenger into a cross-platform ecosystem: a public desktop beta (Tauri) sharing one Rust cryptographic core with the web app, so one security audit covers every platform. Native mobile apps and a decentralized node network for peer discovery are now in active development - moving toward zero reliance on any central infrastructure, even for connecting.

Free end-to-end encrypted P2P messenger that runs entirely in your browser. No accounts, no servers storing your messages, nothing to install.

Keys are generated on your device and exchanged peer-to-peer. No accounts, no servers storing your messages. ECDH P-384 key exchange, AES-256-GCM payloads, ECDSA signatures and full ASN.1 validation - composed into one hardened pipeline. Messages travel directly between devices over WebRTC. No relay holds your data - the server only helps two peers find each other. Session keys rotate continuously and are discarded after use, so a single compromised key can never unlock past conversations. Packet sizes and timing are padded and randomized, hiding metadata patterns from anyone watching the wire. No accounts, no logs, no message storage. There is nothing on a server to leak, subpoena, or…from securebit.chat

  An Elliptic Curve-Based Secure Chat, Written Using Rust and Protobuf2024 · github.com · ▲66

  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 :)

  Secure ChatGPT – a safer way to interact with generative AI2023 · github.com · ▲35

  Hi HN, I’m the founder of Pangea. We’ve built a developer platform where you can easily add security to your code through a simple set of APIs - features like authentication, secrets management, audit logging, redaction of PII, restricting embargoed countries, known threat actor intelligence, etc. With the ChatGPT and LLM explosion, we thought of ways to reduce the risk of both the inputs and outputs from these services. Our NextJS sample app adds a security layer on top of ChatGPT with various security services that you can implement quickly. It’s basically a front end to the OpenAI API…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Strange Attractors▲804

  I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

  Autism Simulator▲779

  Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
