A simple way to send secrets between teammates

Hacker News

hey there. at every job i’ve had, people paste secrets into Slack and delete them really fast. i wanted a quick, secure way to hand off a credential that wasn’t that, so I built 30s. it’s a CLI that generates a local keypair and uses envelope encryption so the server never sees plaintext. you send to a recipient’s email, they decrypt locally, and secrets expire automatically (default 30s, maximum 24h). free to use, 50 secrets/month.
