What it does

Encrypts a message so it can only be unlocked after a future time, using public randomness from the drand network.

How it's safe

The message is encrypted in your browser. The site may proxy drand for timing, but it never needs your plaintext.

Watch out

Once the unlock time arrives, anyone with the ciphertext can decrypt it. Don't rely on secrecy after the unlock moment.

Lock a message to the future. Timelock encryption using public randomness from the drand network – your secrets stay local and only unlock once the network reaches your chosen time.
