Very cool. Like what devhxinc said this is hugely useful. I was not looking forward to trying to decipher let's encrypt at home. I'm impressed how quickly this was put together.
This is neat tool especially for people like me who run custom web servers or web server software that is not supported by the Let's Encrypt client.
What is the difference in this against StartSSL? It’s free, automated, and open ?
Well for one StartSSL charges to revoke certificates.
