Oblivious HTTP for Go

I couldn't find a suitable go implementation for Oblivious HTTP Client & Gateway (RFC 9458). So, I'm open sourcing ours. Some background: OHTTP is a protocol that hides who you are from the data you send - if you've ever used products of Apple, Mozilla, Fastly, or Cloudflare (to name a few) you probably used OHTTP. Key Features: - implemented as http.RoundTripper - supports chunked transfer encoding - customizable HPKE (e.g., for custom hardware-based encryption) - built on top of twoway and bhttp libraries Repo: https://github.com/confidentsecurity/ohttp Detail:…

In plain words

Oblivious HTTP for Go is a Go implementation of RFC 9458 that allows clients and gateways to hide user identity from the data they send. It works as an http.RoundTripper and supports chunked transfer encoding and customizable HPKE encryption, built on the twoway and bhttp libraries. The tool is designed for developers building privacy-focused applications similar to those used by Apple, Mozilla, Fastly, and Cloudflare.

    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…

    Hey 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…
