I'm so excited for this to take off, and it's good to see they've taken the first steps, but can I at least download the CA Cert over HTTPS? Not sure how comfortable I am installing a CA cert I downloaded via HTTP, since that's kind of the whole point of this whole thing.

You can download the cert via HTTPS from https://letsencrypt.org/certs/isrgrootx1.der

Fixed, thanks for pointing that out.

No problem :-) I actually noticed the link was HTTPS (presumably after you changed it) and thought I was taking crazy pills.

This is a tiny bit odd. So they have issued their first certificate, but they don't have cross-signing in place yet? So between now and november 16th they'll be issuing a whole bunch of effectively broken certificates unless people manually install their root CA? Why even push this today if you don't have cross-signing available? Without that Let's Encrypt is effectively broken out of the box. PS - I actually like Le…

It's a bootstrapping process, I don't think they can be accepted as a root certificate until they have proved their automated issuing system it working.

One way to prove that their automated issuing system is working, is to turn it on.

Looks like they have set it up to only issue certificates for white-listed domains in the beta program, and they will switch to General availability in the Week of November 16th.

To be honest I had not heard of them till now, and I am a bit confused even after reading some of their site... So if the difficult part of being a CA (which I think is verifying that I, Paul Brian, own and control the rights to barlcaysbank.com and should have a certificate in that name) if that bit is either not done (!) or is reliant on donations to be able to afford it, is this going to work?

This is not what regular style certificates verify. That is what Extended Validation certificates verify and they're not issued by letsencrypt.org and generally are a lot more expensive.

The only thing that regular-style certificates verify (this is what current CAs do, you can also grab a free one with automatic validation at https://www.startssl.com/) is that the person who controls the domain name has requested the certificate. This is usually done by serving a specific file over HTTP once, setting a TXT DNS record or responding to mail to postmaster@yourdomain.tld

I don't understand what it is we should "beware" of? What's the perceived threat? In theory, even if the NSA themselves were creating these site certificates, because of how they're created (i.e. you generate the keyset yourself locally, they sign the public part), it should be secure. So as I said: What is the perceived threat condition here?

That's a great example, I'll have to keep it in mind. I'd never thought of such a great example that clarifies how strong the security is, and how it's orthogonal to the trust model.

who the fuck upvoted this back up from being negative?

mahouse, I recommend growing up. running around writing crap like this and saying "TRIGGERED" as if you're some genius hilarious douchebag just makes you look like an ignorant loudmouthed child.

You should read back over their blog to see how much planning has gone into this so far. This isn't a single-file LAMP app running on a VPS, they're setting up a CA trustworthy enough to have its roots in all the major browsers

I'd like to see LetsEncrypt move into this territory though. What current private business providers are charging for this service is border-line extortion.

Note that if the CA has the authority to sign certificates, they don't need your private key. They can just locally create a CSR for your domain, sign it, and have their own equivalently valid certificate for your domain.

Moreover, in the absence of HPKP, any CA can do this for any domain.

According to TFA, Firefox already trusts this cert.
