Somehow, end up with this product. :O Flashpaper is for sending any information that would be burned after reading (with counting down timer like Mission Impossible movie ! or after 24 hrs max if not…

Stasher – Burn-after-read secrets from the CLI, no server, no trust▲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…

64.surf – share files using only the URL▲16
Hey HN, I built this to scratch an itch I had around what can be done solely using the URL. It's very minimal with no storage involved, and your files can even be encrypted. The only caveat is some platforms wont allow you to post long links. I thought about using a URL shortener, but storing and mapping URLs kind of defeats the purpose. However most browsers do allow you to open them once you have them. For instance I was able to "share" a 10MB file using safari, however 350KB seems to be the max for Chrome.
