About CipherRoom
Why we built a platform for temporary encrypted rooms — and how CipherRoom encryption keeps your data private.
01. What is CipherRoom?
CipherRoom is a privacy-first platform that lets you create temporary encrypted rooms for secure file sharing, real-time chat, and collaborative notes. Every room is password-protected, end-to-end encrypted, and automatically self-destructs after a chosen time (1 hour, 6 hours, or 24 hours).
There are no accounts, no signups, no email verification. You pick a temporary display name, create a room, and share the link. When the timer runs out, everything is permanently destroyed — messages, files, notes, and the room itself. Zero recovery. Zero traces.
02. Why CipherRoom Exists
Every day, people send sensitive files through email, Slack, Discord, and Google Drive — tools that store copies indefinitely, can be subpoenaed, or get breached. There was no simple answer for the question: "How do I share this file securely, once, and have it disappear?"
CipherRoom was built to be that answer. Whether you need ephemeral file sharing for a contract, a self-destructing chat for a private conversation, or a quick temporary encrypted workspace for a team handoff — CipherRoom provides it without requiring you to create yet another account or trust yet another company with your data.
03. How CipherRoom Encryption Works
CipherRoom uses client-side end-to-end encryption powered by the Web Crypto API. Files are encrypted directly in your browser before they ever leave your device:
Encryption Stack:
• Algorithm: AES-256-GCM — military-grade symmetric encryption
• Key Derivation: PBKDF2 with 100,000 iterations from the room password
• Zero Server Knowledge: raw passwords and unencrypted data never reach our servers
• Room passwords: hashed with bcrypt (cost factor 12) before storage
This architecture means that even if our servers were compromised, attackers would only find encrypted binary payloads they cannot decrypt without the room password — which only exists in participants' browsers.
04. Who Built CipherRoom
CipherRoom was designed and built by Sai Suhas Sharma, a developer focused on building privacy-respecting tools. The entire platform — from the encryption layer to the real-time collaboration system to the auto-destruction pipeline — was built as a solo project with a single goal: make secure, temporary sharing effortless.
