EncryptRoom

What it does

EncryptRoom lets you create a private terminal chat and share invite-enabled apps for Windows, macOS, and Linux. Users open the app, enter a display name (and room password if required), and chat live in the terminal. Security uses HMAC room auth, X25519 + HKDF-SHA256 key derivation, and ChaCha20-Poly1305 encryption with replay protection. The relay only forwards ciphertext in memory and stores no message history.

Create and download EncryptRoom chat bundles.

Create secure room bundles in seconds so organizers, families, and mission-driven teams can coordinate quickly with confidence. This experience is for joining chat rooms on the managed EncryptRoom service. Clients encrypt on the user side, while the relay forwards ciphertext for live room communication. You connect through our hosted relay for room coordination. Messages and display payloads are encrypted client-side before relay forwarding. EncryptRoom is a live room model, not a mailbox. Connected participants see live chat. Offline participants miss messages. You receive platform-specific terminal clients in one bundle so your group can run the right binary and join the same room.…from encryptroom.org

  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…

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
