Zero-knowledge secret rooms

Send a password without leaving it behind.

Paste a secret, choose an expiry, and share a one-time room link. PassRoom encrypts in your browser before anything reaches the server.

Encrypted locally with AES-GCM. The server receives ciphertext only.

1

Encrypt in your browser

AES-GCM runs before upload, so plaintext never leaves your device.

2

Share the room link

The decryption key stays in the URL fragment after #, which browsers do not send to servers.

3

Self-destruct on open

After a valid open, PassRoom deletes or consumes the ciphertext on the server.
