The Cipher Lab

A modern playground for classical cryptography.

The Cipher Lab launched on January 13, 2026. The site was not reachable when checked in September 2026.

What it does

Existing sites offer all the same basic tools, which is fine, but I wanted to offer something more- something it felt like a real cryptanalyst could and would use, but still accessible even to absolute beginners. The Cipher Lab offers a comprehensive environment to learn about, solve and create your own ciphers. For beginners and experienced cryptanalysts.

    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…

    Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
