While there are many ways to generate strong passwords, I’ve been a fan of using pwgen for systems that I stand up. It’s usually been an “apt-get install” away, but there have been times while away from a Linux machine where I couldn’t access it like I normally would; right on the cli.
After coming across a Docker image that sets up most of the environment to compile a C/C++ project using Emscripten, it got me thinking that it might be easier than I thought to build a Wasm version of the original pwgen. It progressed something like this, “I can currently use it on the Linux command line—but with WebAssembly on Node.js and Wasmer, I could run it on Mac OS X, Windows, and really anywhere a runtime is—I think I can wrap this in a custom element.”
So, I gave it a shot, and I couldn’t be more pleased with how easy the results are to use and in how many environments it runs on. Does the system already have a recent setup of npm/npx installed? Start generating passwords with the command below (wapm is similar), or pass “‐‐help” for additional options to be printed.
What about from the browser?
<x-pwgen></x-pwgen> <script type="module"> import 'https://unpkg.com/pwgen' </script>
Finally, I felt like this was a good opportunity to investigate Web Bundles [1 ,2] seeing how the hosted version is a just a set of static files. If you use Chrome 80 or higher and want to test it, set your browser’s
chrome://flags/#web-bundles flag to
enabled, download the pwgen.wbn file, and then drag and drop it onto a Chrome window.
