docLet
Hi HN, I built DocLet, a zero-knowledge cloud storage system where all encryption happens on the client and the server never receives the encryption key — not even an encrypted form of it. The goal is to give users full control over their data without relying on provider trust. A few technical differences from existing encrypted providers like Proton Drive: • Client-side key handling: Proton Drive encrypts files end-to-end, but the server still receives an encrypted version of the user’s key. In DocLet, the encryption key is generated and stays entirely on the user’s device. We never see it,…
docLet launched on October 15, 2025 with 7 votes, #2,779 of 8,178 launches that month. The site was still online in September 2026, 1 year on.
What it does
docLet is your zero-knowledge encrypted digital vault. Safely store your ID cards, licenses, and documents with end-to-end encryption. You will ask to set a secret code so the document will be encrypted by it. And only you can read it.

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Autism Simulator▲779Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
