TimeCapsule Vault
A cryptographic vault that seals data until a chosen date — time-locked encryption with a CLI.
Runs natively — not a browser app
Ask me about this
The problem
"Open this later" is a promise unless the cryptography enforces it.
How I approached it
The unlock condition is built into key derivation rather than checked by the application, so early access fails at the crypto layer, not at an if-statement.
The outcome
A time lock that holds even against the person who made it.
