Products that do what Portable Secret – Open-Source HTML files that self-decrypt offline does
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…

I have written a passwords/secrets manager for my personal needs. Maybe it solves some of your problems too. It is written in Go and is a self-contained executable for a small web-app: https://github.com/jarmo/secrets-web There is also a CLI version if that is your taste: https://github.com/jarmo/secrets-cli To read about more technical details, look into the core repository at https://github.com/jarmo/secrets Any questions/comments/suggestions are welcome in here or via GitHub pull requests.

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…

Hey HN! I made a service to share passwords easy and secure but never promoted it. It's called instapass.io I noticed that people besides my friends and clients actually started to use, so maybe it will be helpful for you too! You share one-time self-destruct message using one time links and I won't even be able to see what you wrote. How does it work? When you generate a message the client-side makes a random password and use that to encrypt the message. The password is appended as an anchor tag which all modern browsers never send to the server. This way, I don't even know what you shared.…

Hi HN! I built hidetext.sh — a way to share text, code, and files through links the server can't read. How it works: your browser generates a random key and encrypts everything locally (NaCl secretbox, XSalsa20-Poly1305). Only ciphertext is uploaded. The key goes into the URL fragment — the part after # — which browsers never send to servers. The link carries the key, my server stores the locked box, and the two only meet in a browser. A design detail I'm fairly happy with: burn-after-read doesn't destroy the paste on the first HTTP request. The naive version means a Slack or iMessage link…

Hi HN, I’ve been working for the past 10 months on p2party, a TypeScript/C/WASM library which you can find at https://github.com/p2party/p2party-js and demo at https://p2party.com , that lets you spin up an encrypted peer-to-peer mesh with nothing more than a shared URL. Why I built it: I wanted something between https://file.pizza and “ephemeral Signal chat”, but with my custom cryptographic idea (I know I know... WebRTC is already encrypted and it is easy to go wrong etc.). The project started as a toy for sharing large DAW files with my…

AuthWeb is a minimalist web-based tool for generating secure TOTP tokens and passwords. Built with privacy and security in mind, all computations are performed client-side with no data storage. Key features: - Generate TOTP tokens with QR code support - Configurable password generator (single/batch mode) - Zero data collection or storage - Clean, responsive UI built with Tailwind CSS - Self-hostable and open source under MIT license The project aims to provide a reliable alternative to proprietary authenticator apps while maintaining simplicity and user privacy. QR codes are generated…

Hello. I made this project as an experiment in using key cryptography for user identity in a client server model, and for some future peer to peer projects that I am working on. I am looking for feedback, please let me know what you think. Also, Merry Christmas to HN! :-)

Hello HN! We are developers and security researchers making tools for developers to encrypt data at an application level while maintaining sole control of their keys. We believe that data should always be encrypted unless it is part of an active computation. Encryption is relatively easy, but key management is challenging. There are plenty of encryption tools and SDKs that are out there (Hashicorp Vault, AWS KMS etc.) but we are focusing on ease and speed of implementation, developer experience and self custody of keys. A few months ago, we quit our jobs and started full time on Phase. So…
