PageLock

Hey HN! I'm the creator of PageLock. I built this because I kept running into situations where I needed to share sensitive URLs (private docs, beta links, etc.) but didn't want to trust a third-party service with the data. How it works: - Client-side AES-256-GCM encryption using Web Crypto API - Your password and original URL are encrypted in the browser before storage - Zero-knowledge architecture - None can decrypt links without the password - except someone manages to break AES-256 :0 - Pure frontend (React + TypeScript), no backend database The key insight: by doing encryption…

    Device-Bound Session Tokens in JavaScript2024 · session-lock.keyri.com · ▲23

    Google’s recent announcement of a proposed ‘Device Bound Session Credentials’ feature[1] for Chrome reminded me of a project we worked on last year at my company. We focus on fraud prevention at signup and login (preventing multi-accounting and account theft), but some customers were concerned about post-login security and asked us to add a session hijacking prevention feature to our fraud prevention API. In the end, we decided to just implement a solution in Javascript. We call it session-lock, and it can be used today across all browsers[2] and, theoretically, native mobile apps. For a…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
