No worries! Every time I see a Let's Encrypt thread on HN, there's always complaining about having to trust the official client with root access, webserver configs, dependencies, or whatever. So I made my clients (letsencrypt-nosudo, gethttpsforfree.com, acme-tiny) to shut those people up. My clients are not intended to serve the wider Let's Encrypt target audience, who probably don't know what a CSR is. But for those who do, I made clients that don't ask for the access/trust that the official client needs to serve its target audience.

Thanks for making Let's Encrypt and ACME!

Maybe you can consider getting someone at Let's Encrypt review diafygi's acme-tiny code and, if approved, propose it as an alternative on the Let's Encrypt site. This will be very useful for users who get turned off by the root requirement or the number of dependencies.
