Timelock encryption (tlock / encrypt-to-the-future): seal a payload toward a future drand

Timelock encryption (tlock / encrypt-to-the-future): seal a payload toward a future drand round — undecryptable by anyone, including us, until that round lands; or open a landed seal. For sealed-bid auctions, commit-reveal, scheduled secrets, dead-man switches. age-armored, interoperable. Free zero-knowledge inspect at /sealed/inspect.
