Utils

Utils was my first foray into writing Rust for WebAssembly. I wanted a set of small utilities I could reach from any browser without relying on the ad-heavy versions that tend to dominate search results or having to trust what those sites might do with the data I gave them.

A password generator made the problem concrete. Browser developer tools can show whether an unfamiliar site calls home, but auditing network traffic is an awkward prerequisite for using a basic utility. It is also not intuitive for everyone. I wanted local execution to be the default instead. In Utils, the page, styles, JavaScript glue and WebAssembly module are static files served by GitHub Pages. Once those assets are loaded, using a tool makes no further network requests: the Rust code does the work in the browser. The source is public, so that behavior can be checked in the code as well.

The project currently includes a deterministic password generator and a JWT decoder. Each utility is its own Rust module, registered with a small hash-based router, which keeps the collection easy to extend. The idea is to add tools one at a time as I need them and gradually build a useful repertoire without turning the site into a larger application than it needs to be.
