Yes, if you are skeptical about this, so am I.
The project promises:
Sounds too good to be true, right?
Anyone who has gone through the trouble of setting up a secure website knows what a hassle getting a certificate can be. Let’s Encrypt automates away all this pain and lets site operators turn on HTTPS with a single click or shell command.When Let’s Encrypt launches in Summer 2015, enabling HTTPS for your site will be as easy as installing a small piece of certificate management software on the server:
$ sudo apt-get install lets-encrypt
$ lets-encrypt example.comThat’s all there is to it! https://example.com is immediately live.
So let's wait until Summer 2015 and see what is left from it then. Don't get me wrong, this would be awesome and I'm all for it.
I really hope it works that way. For people without having a server on their own to maintain, this might not be a big thing.
Commercial server sites will continue to give out their own certificates for extra $$$. We will see how much impact this will have at last.
