Show HN: Timelocked – local, offline timed-release file encryption

This is a small Rust app for encrypting files that can only be unlocked after a chosen amount of time.

You can 'timelock' any file, the content is encrypted with a key and that key is then protected by a sequential time-lock puzzle (Rivest-Shamir-Wagner style). Unlocking requires non-parallelizable computation time rather than waiting for a server or trusting a third party.

Possible uses:

- Delayed release of important work, scientific results, or investigation proof before making the reports/papers/final touches

- Timelocking crypto currencies BIP-39 passphrases for added security against home invasion / kidnapping

- Self managed inheritance plan. Put your timelocked passwords or files in a USB drive (or printed for maximum shelf life) in a temper evident bag in your home safe. If the bag is opened too soon, you will have time to reset your passwords.
