24 alternatives to Hidetext.sh – encrypted pastebin where the server never sees the key
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, creator here. This is a demo of our recent work presented at Oakland (IEEE S&P): https://eprint.iacr.org/2022/368. The server and client code are written in Rust and available here: https://github.com/menonsamir/spiral-rs. The general aim of our work is to show that homomorphic encryption is practical today for real-world applications. The server we use to serve this costs $35/month! A quick overview: the client uses homomorphic encryption to encrypt the article number that they would like to retrieve. The server processes the query and…

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…

Retriever (https://retriever.corgea.io/), an open-source research project to help users receive secrets and sensitive information without needing a server in the middle. It works by using Public-key cryptography to coordinate the message sharing between the two devices. Read more on why we built it here: https://retriever.corgea.io/why.html

Hey HN, I've been playing around with OpenPGP.js and Soketi lately and decided to build a simple E2E encrypted messaging app. It's called subtle.sh. The idea is pretty straightforward: you need to send a secret to someone, but you don't want to use Slack, email, or any other plain text medium. subtle.sh generates a fresh session with ephemeral keys, you share the link, and once the tab is closed, everything disappears. Some key points: - Zero setup required (no accounts, no installation) - E2E encryption using OpenPGP.js - Real-time messaging with Soketi (an open-source Pusher alternative) -…
