If you are seeing this, it means that you have JavaScript disabled. Please enable JavaScript to access the locked link.
This application is entirely programmed in JavaScript. This was done intentionally, so that all encryption and decryption happens client-side. This means the code runs as a distributed application, relying only on GitHub Pages for infrastructure. It also means that no data about locked links is ever stored on a server. The code is designed to be auditable so users can investigate what is happening behind the scenes.
If you still want to run the application, I encourage you to clone the source code on GitHub. That way you can disable JavaScript only for trusted files on your local machine.
