PrivacyProtect – Portable Secret improved: encrypt and store secrets
On the 40-day anniversary of the Portable Secret Show HN (https://news.ycombinator.com/item?id=34083366), I introduce PrivacyProtect. Portable Secret's mprime1 has little time for upkeep, so, with his blessing, PrivacyProtect picks up where he left off and incorporates the following updates, - Improved security - SHA-512 and 2,100,000 iterations instead of SHA-1 and 1,000,000 - Generate IV and salt at encryption time to prevent reuse - Clear forms on submit - CLI: still WIP, but have a proof of concept working of using NodeJS's WebCrypto APIs to create the HTML files without…

- PSPortable Secret – Open-Source HTML files that self-decrypt offlineFeb 2026 · alcazarsec.github.io · ▲5
Hey HN, We've decided to open-source our Portable Secret. It's a free tool that generates self-contained HTML files which decrypt locally in your browser. Check it out at https://alcazarsec.github.io/portable-secret/. Source code: https://github.com/alcazarsec/portable-secret The project is inspired by an old post (https://news.ycombinator.com/item?id=34083366) by mprimi, who coined the term "Portable Secret." I really liked the idea and wanted to improve the security of the KDF and the UX. I hope he's honored that so many people have…

Talanoa▲346Hi 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…

This works suprisingly well. Just give it instructions like "make it winter" or "remove the cars" and the photo is altered. Here are some examples of transformations it can make: Golden gate bridge: https://raw.githubusercontent.com/brycedrennan/imaginAIry/ma... Girl with a pearl earring: https://raw.githubusercontent.com/brycedrennan/imaginAIry/ma... I integrated this new InstructPix2Pix model into imaginAIry (python library) so it's easy to use for python developers.

The project is called QueryStorm. It uses Roslyn to offer C# (and VB.NET) support in Excel, as an alternative to VBA. I've posted about it before, but a lot has changed since then so figured I'd share an update. The current version includes a host of new features, namely a C# debugger, support for NuGet packages, and the ability to publish Excel extensions to an "AppStore" (which is essentially a NuGet repository). The AppStore can be used by anyone with the (free) runtime component. Another great addition is the community license, which is a free license for individuals and small companies…

Hey HN! Some more info: I’m an NHS doctor and the founder of Pi-A (https://www.pi-a.io) which developed Lungy (https://www.lungy.app). Lungy is an app (iOS only for now) that responds to breathing in real-time and was designed to make breathing exercises more engaging and beneficial to do. It hopefully has many aspects of interest to the HN community – real-time fluid, cloth and soft body sims running on the phone’s GPU. My background is as a junior surgical trainee and I started building Lungy in 2020 during the first COVID lockdown in London. During COVID, there were…
