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.see more

About

Imagine needing a secure, immediate space to discuss sensitive information with a trusted colleague or small team, where every word spoken vanishes the moment it's read. That is the core promise of EncryptRoom. This isn't just another messaging app; it's a dedicated, ephemeral communication channel built from the ground up for absolute privacy and zero retention. You can instantly spin up a private terminal chat room, share a simple invite link, and have your team join directly from their Windows, macOS, or Linux machines. The beauty lies in its simplicity: users just enter a display name, perhaps a room password if the conversation demands extra layers of trust, and immediately start collaborating in a clean, familiar terminal interface. This setup is perfect for quick, high-stakes discussions where logging and history are liabilities, not assets. It’s about having a secure conversation that leaves absolutely no digital footprint behind, offering peace of mind in an age of constant surveillance.

What truly sets EncryptRoom apart is the robust, state-of-the-art cryptographic foundation securing every single byte of data exchanged. We are talking about enterprise-grade security implemented flawlessly for everyday use. Your messages are protected using a powerful combination of X25519 for key agreement and HKDF-SHA256 for secure key derivation, ensuring that only authorized participants can ever decrypt the conversation. The actual message content is shielded using ChaCha20-Poly1305 encryption, which is known for its speed and strong security guarantees, complete with built-in replay protection to stop malicious actors from tampering with the message order. Furthermore, the relay server itself is designed as a blind conduit; it only ever handles the encrypted ciphertext in volatile memory, meaning there is zero message history stored anywhere on our systems. If the server goes down or is compromised, there is nothing to find because nothing was ever saved.

This focus on ephemeral security makes EncryptRoom an indispensable tool for developers sharing sensitive code snippets, legal teams discussing confidential case details, or anyone requiring a truly private, real-time communication channel without the baggage of traditional chat platforms. Because it operates entirely within the terminal, it integrates seamlessly into existing workflows for technical users who prefer command-line efficiency. It’s about providing a trusted environment where the focus remains entirely on the conversation at hand, knowing that the infrastructure itself is designed to forget everything immediately after transmission. If your work demands absolute confidentiality and a commitment to non-retention, EncryptRoom offers the most direct and secure path to getting your message across.
