So a slight delay then, previously they announced general availability for November 16th: https://letsencrypt.org/2015/08/07/updated-lets-encrypt-laun...

conorgil145• 11 years ago

Given the scope of what they are trying to accomplish and the fact that I've never worked on a project which was delivered on time and with all features complete, I'm pretty happy that the delay isn't longer! :)

CzarSpider• 11 years ago

And before that it was announced that general availability was going to be September 14th: https://letsencrypt.org/2015/06/16/lets-encrypt-launch-sched...

It's a shame they've pushed it back twice so far.

fenesiistvan• 11 years ago

I am still unable to run the tool to get the certificates on Windows OS. I know that there are some development in progress, but still far to be finished. Windows OS is running around 30% of the web servers. Please don't neglect it.

sarciszewski• 11 years ago

They won't. :|

gluejar2• 11 years ago

Don't feel so bad, it doesn't run on Mac OSX or even RHEL. Use the Docker container, it worked for me.

rascul• 11 years ago

Works fine on FreeBSD, also is in ports.

technion• 11 years ago

I'd be interested in whether my script[0] works on Windows, aside from the obvious fact most Windows servers don't have Ruby.

You could also just put a gets on line 43 to pause it before the verify, and copy the generated verify files onto said Windows server from any Linux box anywhere.

voltagex_2• 11 years ago

Anyone want to help write a Powershell version?

Edit: https://github.com/natemrice/letsencrypt-powershell could use a hand.

I can't afford to spin up too many Windows servers on AWS but I'd like to have a look at this.

flyingmutant• 11 years ago

Is there finally a way to renew the certificate without taking down the web server listening on :443? This was the major thing missing from being able to deploy it in production.

the_angry_angel• 11 years ago

There are multiple modes to the letscrypt client. The [webroot mode](https://github.com/letsencrypt/letsencrypt/issues/1370) allows you to use an existing web server.

SuperKlaus• 11 years ago

There's no downtime when using the webroot method, see here for details: https://community.letsencrypt.org/t/using-the-webroot-domain...

ge0rg• 11 years ago

The downtime happens when you restart the server so it loads the new certificate. This must probably be addressed in the server implementation.

mholt• 11 years ago

If you're willing to use an alternative web server, this is possible: https://caddyserver.com/blog/lets-encrypt-progress-report

Caddy (currently in beta) will issue and renew SSL certificates automatically with no downtime (on Linux; Windows has very brief downtime during restarts).

bketelsen• 11 years ago

I can confirm that Caddy + Let's Encrypt is the most seamless and awesome way to run TLS. I did this last night for one of my LE beta whitelisted domains and it took MAYBE 4 minutes. Caddy did all the work. Kudos to the Caddy team for such a great admin experience.

IshKebab• 11 years ago

Yeah I don't understand why it doesn't check for proof-of-ownership on a different port.

discreditable2• 11 years ago

I am beginning to wonder how much effect Let's Encrypt will really have on wide TLS deployment. A very large portion of the web is stuck at shared hosting services, such as Go Daddy, Lunarpages, et al. These services generally charge for TLS hosting, and due to the 90-day issuance on Let's Encrypt certificates it seems somewhat infeasible to use their certificates on shared hosts which offer very limited (if any) shell access.

atmosx• 11 years ago

A VPS costs 5 bucks on DO and I've seen (can't remember where) a 3 USD/month offering. So it's rather cheap to move away from shared hosting nowadays.

For me Let's Encrypt came out at the right time. They said they will automate the 90-day renewal process.

Diamons• 11 years ago

Side question, does anyone actually enjoy running a VPS? Between managing the sites on it, you have to maintain the VPS, keep it up to date, its prone to security bugs and flaws, etc. Am I missing something here? I remember setting up multiple VPSes on Linode / DO and it was always a painful process of installing the OS, installing the whole stack, configuring everything, setting up users / roles, firewalls, etc.

On top of that, whereas on a shared host i click a button and host a second domain, with a VPS I have to SSH in and manually edit server files.

But everyone always recommends running a VPS so I can't help but imagine I've either missed some magical tool that makes running a VPS a snap or it's just not a realistic solution for most people.

xienze2• 11 years ago

I don't think cost is what's keeping people on shared hosting versus VPS. It's that there is a whole wide world of people just doing a little static hosting. They don't want, need, or know how to use a VPS.

dspillett• 11 years ago

There are reasonable offerings for between 10 and 20 USD/year (from companies that are even likely to be around long enough for you to use the full year - there are cheaper still from the other sort of company) some with enough CPU+memory+disk space to be useful for more than static hosting too. Look at places like lowendtalk.com for such offers when they turn up.

GigabyteCoin• 11 years ago

I've seen (can't remember where) a 3 USD/month offering.

You're probably thinking of http://lowendbox.com/

sofaofthedamned• 11 years ago

Let's Encrypt is brilliant and the web needs it but the tooling isn't quite there.

For example with haproxy you need the entire chain and private key together, which I have to do manually. As the API is open it's doable - I may even do something myself.

I can't wait until I have something that somebody else or I has written that, once the API is complete, you can stick in a cron job and does the concatenation and reloads haproxy/nginx/whatever. Until then the whole thing is beta.

It's not even the monetary aspect - i'd happily pay for certs, but LE is so on the way to making it a devop as opposed to a finance/ops thing that it needs to be encouraged. Donation incoming...

bracewel• 11 years ago

Many hosting providers are choosing to integrate LE into their products directly so even if you don't get shell access you will still be able to get a cert. As far as I know both Plesk and cPanel are also working on official plugins for their software.

pfg2• 11 years ago

That's a good point, domain registrars like GoDaddy generally don't make much on domains alone and focus on selling additional services like hosting packets (and SSL), where they probably make most of their money.

However, most browser vendors are already making plans to phase out HTTP without TLS by only providing new features/APIs to HTTPS sites (and eventually by displaying http:// as insecure in the UI).

I think in the end this will force shared hosting providers to include domain-validated certificates (from e.g. letsencrypt) in their base packages for free. Instead, they would probably push OV and EV certs to make up for any revenue loss.

pilif• 11 years ago

I would imagine that shared hosting providers will just request the certificate for you in the future. Remember: This is about domain validated certs, so there's zero difference whether you request the certificate or whether your hoster does it for you.

tombrossman3• 11 years ago

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!

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.

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.

kevinreedy2• 11 years ago

I actually love the idea of 90 day (or less) certificates! Once you automate the process of replacing your certificate (which let's encrypt will greatly help with), it won't matter how short the period is. Also, if a key gets compromised, it'll be valid for a shorter time. Give https://letsencrypt.org/2015/11/09/why-90-days.html a read! If you want to get more in-depth about certificate revocation, http://news.netcraft.com/archives/2013/05/13/how-certificate... is also a great/depressing read.

ars• 11 years ago

If someone compromised the key they also compromised the system used to automatically generate more keys, so a short expiration is not as helpful as it looks.

It's even worse than that:

A smart attacker will copy the method used to generate keys, and leave the server. Then they can keep generating keys and you will probably never notice.

I feel that automation is a mistake, something security sensitive like this should be on a completely different machine.

bmelton2• 11 years ago

Does Google still penalize short-term / soon-expiring SSL certs in search rankings?

Edit: this does not appear to be a thing that happens.

gluejar2• 11 years ago

I think you really have to understand that at its heart, Let's Encrypt is not about free certs as much as it is about automatic certs. If you just want a cert, definitely use an established provider. But a year from know, LE will be making this a "set and forget" thing, which is how it should be. LE is NOT a painless way to get certs for legacy infrastructure. I found this out by using it for an elastic beanstalk hosted site. I just wrote about it at https://go-to-hellman.blogspot.com/2015/11/using-lets-encryp...

toomuchtodo• 11 years ago

On the plus side, Amazon could choose to automate IAM SSL storage and renewal through Let's Encrypt so it would be fully automatic. Might take a bit until they do that though...

Paging /u/jeffbarr?

joshmoz• 11 years ago

Head of Let's Encrypt here.

You nailed it. It's important that our certs be free because we can't automate a billing interaction. If we had to charge then sysadmins couldn't just type a command and be on their way. Automated renewal could fail because billing info was out of date. This stuff has to just work, reliably, if we're going to expect the entire Web to use TLS.

Maakuth• 11 years ago

There's definitely some rough edges on the tooling that will make this less painful. You likely used it with development endpoints, which only give certificates signed by untrusted CA (happy hacker fake CA or something like that). However, the point[1] of short lifetime of the certificates is to incentivize automating it. I'm highly hopeful that in a short while, having an HTTPS certificate is a matter of apt-get install.

[1] https://letsencrypt.org/2015/11/09/why-90-days.html

tombrossman3• 11 years ago

Here's the issuer from the certificate I got, and I believe it was the (beta) production one and not the development endpoint.

Issuer: C=US, O=Let's Encrypt, CN=Let's Encrypt Authority X1

Possibly user error still, but I use HTTPS across all my personal sites and they all rate well on third-party tests so I'm not a total noob (I hope...).

diafygi3• 11 years ago

Howdy, I wrote letsencrypt-nosudo. Sorry that the experience was so painful! Mind filing a detailed issue on the repo so I can fix it and make the user experience better?

tombrossman3• 11 years ago

Oh I think it's simple enough and thanks for the tool, but I'm comparing it to the workflow I currently use which has fewer steps (generate CSR, paste in form on issuer's website, click link to validate domain). Headed out now but I'll try to provide some better feedback later.

matt4077• 11 years ago

I am actually incredibly happy with the process. nginx requires these concatenated certificates and I always get the order / file formats / trailing spaces wrong. With LE I got it up & running in < 3 minutes, including manually updating the config file.

mobiplayer• 11 years ago

You need to present your full certificate chain and not only your public cert.

I'm running a certificate generated with Let's Encrypt on one of my sites and I've got an A+ result: https://www.ssllabs.com/ssltest/analyze.html?d=datasnitch.co...

flavmartins2• 11 years ago

Anyone concerned with the amount of fraud that will come from this? Won't bad actors utilize this to https all of their phishing sites?

foldor• 11 years ago

What benefit would a phishing site have with https that they didn't have without it?

GavinMcG• 11 years ago

The green padlock that casual users might misinterpret as meaning "to be trusted".

Bedon292• 11 years ago

These certs are to verify you control the domain name, not that you are who you say you are. Those certificates are much more complicated and expensive. See https://letsencrypt.org/2015/10/29/phishing-and-malware.html for more information

cpeterso• 11 years ago

What is the value of checking Google's Safe Browsing API before issuing a certificate when the browser can/should use the same Safe Browsing API to block the phishing website? Move the policy to the user agent.

blibble• 11 years ago

the vast majority of phishing websites I seem encounter these days are all wrapped in https by cloudflare.

seems that letsencrypt unlikely to make the problem any worse!

Absentinsomniac• 11 years ago

Hopefully some kind of OpenBSD support comes along. Pretty much letsencrypt-nosudo until then. The standard letsencrypt program doesn't appear to work on Debian 7 due to outdated openssl and what not.

plnii• 11 years ago

The beta was good timing for me. I installed an LE cert on Ubuntu running Apache and it's working fine. The instructions were a bit unclear about whether the "auto" option works yet for that setup (it doesn't). Also, I had an issue with permissions on the cert directory - I use a group for my server permissions (instead of running at root), so had to add that group to the cert directory. But the process is still better than what I've experienced implementing a comodo cert.

Aissen• 11 years ago

I tried the beta: it was fast, easy and boring. How it should be.

BrandoElFollito• 11 years ago

This is a fantastic solution for public web sites. Kudos to the team.

It is hardly usable for internal (non-Internet facing) ones because you have to expose either the site or internal DNS for a check to go though.
