Issue a cert from Ruby


I’d like to be able to automate creation of certs from our Ruby based web service. Is that something we’ll be able to do with Let’s Encrypt?


Your Ruby web service can call out to the Let’s Encrypt command line interface. I’m not aware of any native Ruby clients for Let’s Encrypt, though.


Hey Jason,

I’ve started working on a ruby client sometime ago, you can find it at

Its a partial implementation of ACME and the API still need polishing but I wanted to get the ball rolling.

Its a side project at the moment but I’m planning on using it in a production system later this year / early next year, so you can expect further development.

Contribution are more than welcome obviously.
