ScorchPad
Zero-knowledge encrypted pastes. Not even we can read them.
What it does
Most "privacy" tools mean "we promise not to look." ScorchPad makes it structurally impossible. Your browser encrypts text locally. The key lives in the URL fragment — never sent in HTTP requests. The server never sees it. We cannot read your pastes, comply with data requests, or identify you by IP. — Burn-after-reading: atomic, race-condition proof — AES-256-GCM + PBKDF2-SHA256 (310,000 iterations) — Monthly warrant canary — Fully open source Built by Rsaat Labs 🔒

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…
- SBStasher – Burn-after-read secrets from the CLI, no server, no trust2025 · github.com · ▲72
Stasher is a tiny CLI tool that lets you share encrypted secrets that burn after reading — no accounts, no logins, no servers to trust. I built it because I just wanted to share a password. Not spin up infra. Not register for some "secure" web app. Not trust Slack threads. Just send a secret. Secrets are encrypted client-side with AES-256-GCM. You get a `uuid:key` token to share. Once someone reads it, it's gone. If they don't read it in 10 minutes, it expires and deleted. Everything is verifiable. Every release is signed, SLSA-attested, SBOM-included, and logged in the Rekor transparency…

- H6Homebrew 6.0.0▲1,481
Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
