I made this because I've seen too many secrets (API keys, passwords, private keys) shared via Slack and MS Teams etc. I've even had a private API key or two in my gmail inbox because someone DM'd it when I wasn't there. I know some password managers make sharing secrets fairly easy, but I'm often working with clients who don't use the same tools and need a secure way to get .env files and such.
