The documentation says, that I can get a certificate without apache configuration, if I run the command “letsencrypt -d example.com auth”
But how does the tool validates, that I’m eligible to receive the cert for the domain?
Looks like a simple HTTP request.
Then it would be very nice to have an additional in browser solution like https://www.startssl.com/
startssl also does a simple http validation by sending an email to the domain. Then the startssl website uses a browser feature/function to generate the certificate at the client site.
The big benefit is that a certificate can be issued OS independent. This would be very nice for LE also. e.g. I’d like to get a cert for a Windows IIS not for an apache.
