🔐 Timelock Encryption

Encrypt files so they can only be decrypted after a chosen time.
Uses drand quicknet beacons as key material — no server needed, no password, pure cryptography.

How it works: Each file is encrypted with a fresh random AES-256-GCM key. That key is wrapped using a commitment to a future drand beacon round via HKDF-SHA-256. Until that round is published by the drand network (~every 3 s), the key material does not exist — making decryption cryptographically impossible. Everything runs locally in your browser. No data is uploaded anywhere.
