I'm really pleased to see this initiative and I've used the private beta with letsencrypt-nosudo[0] to issue a certificate, but after successfully getting a certificate my site failed the SSL Labs test[1] with an 'unknown CA' error, even though I used the newer one that should have been trusted. It was probably down to user error and the additional complexity of denying sudo privileges for the set up script, but it took much more work than I expected. Then I noticed the certs will only ever be good for 90 days, and I'll have to do this multiple times a year!<p>Bottom line for me is that with DV certs so inexpensive and simple to get, I'd rather pay a few dollars a year for normal commercial certificates. I can do things like use CloudFront at a custom subdomain with HTTPS without needing to point DNS somewhere every few months to get a cert reissued.<p>I simply can't justify the extra work involved to get 'free' certificates, and I'm happy to continue buying regular DV certs. Maybe these are temporary limitations and if so I will definitely try again in the future.<p>[0]<a href="https://github.com/diafygi/letsencrypt-nosudo" rel="nofollow">https://github.com/diafygi/letsencrypt-nosudo</a>
