KeyGenerator.io
Password, JWT secret and AES key generator, fully offline
What it does
Generates passwords, JWT signing secrets and AES keys with crypto.getRandomValues. CSS, JS and translations are inlined at build time, so once the page loads it makes no network requests at all. Open the Network tab and watch it stay empty. 7 languages.
Free online password and key generator. Strong random strings of 6 to 64 characters, made in your browser and never uploaded. Entropy and crack time shown.
Long random passwords, generated in your browser. No network, no logs, nothing uploaded. Press Space for a new password, C to copy. Generated with crypto.getRandomValues on your own device — this page loads nothing from the network. Every password comes from crypto.getRandomValues , the browser's cryptographically secure random source. It is not Math.random, which is fast but predictable and must never be used for secrets. Characters are drawn by rejection sampling: taking a raw random number modulo the alphabet size would quietly make the earliest characters more likely, so out-of-range draws are discarded and retried instead. One character from each category you enable is placed first,…from keygenerator.io

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
