EncryptRoom – Encrypted terminal chat with no message history

Summary: EncryptRoom is an open-source terminal chat app for Windows, macOS, and Linux that enables live, end-to-end encrypted communication without storing message history. It uses strong cryptographic protocols and an untrusted relay that only forwards ciphertext in memory.

What it does

Users create private chat rooms with password-protected access and share platform-specific apps to join. Messages are encrypted with X25519, HKDF-SHA256, and ChaCha20-Poly1305, while the relay forwards only ciphertext and keeps no history.

Who it's for

Teams and communities seeking simple, auditable privacy in terminal-based group chats without complex setup.

Why it matters

It prevents server-side message storage and protects chat content from relay operators, ensuring secure, ephemeral communication.
