Send a message into the future

Write a message and pick a time. Your browser encrypts it. Nobody can read it before that time, not even you or us. After that, anyone with the encrypted text can read it.

Each row is one encryption or decryption. We record the type, the time and the unlock round. Never the message.

We never store your message. For higher security, encrypt offline.
