"I needed to move an API key from my laptop to a production server. So I emailed it to myself. Then I tried Slack DMs. Then a sticky note on my desk. Then I typed it by hand and got one character wrong — twice. Every time, I thought: there has to be a better way to do this."

That frustration is why IronShare exists. No accounts, no apps to install, no complicated setup. Just paste a secret, get a link, share it. It encrypts in your browser, self-destructs after use, and the server never sees the plaintext. The way sharing secrets should have always worked.
