Support for ACME/Let's Encrypt certificate management

bigcw · Fri Jan 02, 2015 6:13 pm

As subject, it would be great if ROS supported the new ACME-protocol for managing browser-trusted certificates from Let's Encrypt.

Let's Encrypt: https://letsencrypt.org/

Protocol spec: https://github.com/letsencrypt/acme-spec

This would be a great feature. Configure a couple of hostnames you want certificates for, and then have the firewall automatically request/renew them with letsencrypt.org. This will save a lot of time, especially when using services that require a valid certificate such as SSTP VPN's.

I agree but isn't Let's Encrypt certificates www-only?

nka · Mon Dec 21, 2015 3:03 am

No, they are "certificats", can be use on anything (firewall, mail, ftp, etc...). The only "problem" is that they are 90 days lifetime... so without ACME, you'll have to update the cert manually each 3 month. Certs are actually working right now if you do install it manually.

but what are they?... proprietary?
Is there a plugin to run a more common type of script like python or bash shell etc.?

Any other suggestions/recommendations for the best route to solve this problem other then in wishful thinking of a RouterOS update one day?

ROS scripting engine is fully custom like terminal. That route was chosen probably due to performance & security reasons.

Nope.

There's no way besides external automation and updating certificates via SFTP.

I see thanks for your constructive input. This explains that even NPKs are not possible and require signing too bad.
http://forum.mikrotik.com/viewtopic.php?t=87126

So it's got to be a script only solution I guess. That explains the rash of +1s without the more constructive discussion I'm more familiar with in the open source community these days. So I gather the RouterOS is something I can NOT download, compile and customize either?

i would envision this feature to be an extension of the current dynamic dns feature. (this also alleviates any off router requisites)

currently ROS can register your wan ip for an auto-genterated hostname like 62190177tk28.sn.mynetname.net.

lets encypt function could register/update the SSL cert for that same hostname...

Plus ones all around, but did anyone give it some thought beyond that it would be nice feature? How exactly it should work to be usable for as many scenarios as possible? Because there are quite a few.

Let's Encrypt allows to verify hostnames using different challenges:

- http - code needs to be placed on http server on default port
- dns - code needs to be placed in dns
- tls-sni - code needs to be served by https server on default port for special hostname

There's no way that just one challenge type would be usable for everyone. Let's say I want to get certificate for SSTP server. If the router is dedicated SSTP server with public address using default https port, then it's easy, it can simply use tls-sni.

But what if IP address is shared with web server (with port 80 and 443 forwarded to LAN) and SSTP uses non-standard port (I think it will be very common setup)? Then the only right option is dns. The problem is, dns is very often hosted by registrar without any automated way to change records, so this option may not be available. The other way would be to have events for LE client, that would allow to write a script to temporarily disable port forwarding to internal web server, set it to local SSTP server and then back after successful verification. It would mean short service interruption for internal webserver, but better than nothing I guess.

It can be even worse, SSTP server might be an internal machine, which has only one non-standard port forwarded to it. That would leave dns as the only option.

Where automated updates of dns records is possible, it would be the best solution. But even that is not completely straightforward, because there may be different ways how to update records, either using standard dns updates, or some custom way, e.g. using http(s) calls to some api. Plus there might be a need to update completely different records (there are some interesting tricks you can do with LE and CNAMEs). So events and scripts is probably the only universal solution here too.

Comments, thoughts, suggestions?

Just a thought and pardon if I fall out the window on this...

What if the created ROS package for this did an inspection of the TLS SNI Domain Hint but only during the setup of a cert if using TLS-SNI mode?
This way it could capture the validation requests and respond appropriately completing the setup for it .
I say during setup only as this would have obvious impacts to resources and services while it inspects.
If users are looking for this feature they might be willing to take that knock during the small setup window every 3months per cert.
(if you don't want to, then don't install the package or setup any certs on it)

How I envisage the package options:
- Global settings for ACME protocol requirements (notification email address, etc...) or maybe allow this to also be set per cert (if anyone has the need for this?)
- allow for more than one cert (you might want different certs for different things)
- allow for multiple SANs per cert, where the first SAN in the list will be the name of the cert (the SNI domain hint inspection would look for all of these during that cert's setup/re-validation)
- allow for auto adding of Cloud DNS to a SAN (makes it easier to not fat finger it)
- allow for service(s) to be specified for use with that cert (hotspot, SSTP, OpenVPN, API-SSL, WWW-SSL, etc) further improving its automation ability
- Allow for different strength keys (more robustness and control)

Notes: why only SAN names... Common Name field removal is well underway (see more on this here: https://groups.google.com/a/chromium.or ... GT2fLJrAeo)
however if users want the CN, so be it, I have no objections to it.

Thoughts?

After trying the script at https://www.ollegustafsson.com/en/letsencrypt-routeros/ for updating an SSTP certificate, I decided to write one that only relies on a BASH script:
https://gist.github.com/JonathanThorpe/ ... 5162dafe43

You'll need the following:
1. Create a DSA SSH Key so that the host running the BASH script can login to MikroTik.
2. Install acme.sh as per the instructions in https://www.ollegustafsson.com/en/letsencrypt-routeros/
3. Update the following:
----
ACME=/root/.acme.sh/acme.sh
DOMAIN=remote.mydomain.tld
CERTPATH=/var/router-certs
CERT=$DOMAIN.cer
KEY=$DOMAIN.key
ROUTER=router_os_IP
ROUTER_USER=username_to_login_to_routeros
----

If the script is run on a cron, it should renew certificates and when they renew, the commands should be run on the Mikrotik to update the cert.

brad0x52 · Tue Nov 14, 2017 12:08 am

I've got a couple routers that I use LetsEncrypt certificates for SSTP. Since it took me a bit to figure out why things weren't working at first, I've included my tweaked scripts below. Additionally, I created a dedicated user on my Linux server for managing certificates and set it up to log into my routers with certificate login. If the username is identical on both systems, it can be omitted in the command as well.

This script runs shortly after acme.sh in cron to upload the certificates to the routers. Yes, I know this would have been more graceful as a foreach loop, but I've only got 2 routers and I was in a hurry.

#!/usr/bin/env bash
set -e
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
DOMAIN=vpn1.example.net
CERT=vpn1.example.net.cer
KEY=vpn1.example.ne.key
ROUTER=<Router 1 IP Address>

cd $DIR/$DOMAIN

if [ -f $CERT ]; then
        echo -n "Uploading $DOMAIN certificate $ROUTER router..."
        scp -q $CERT $ROUTER:$CERT
        scp -q $KEY $ROUTER:$KEY
        echo "done!"
        exit 0
fi

DOMAIN=vpn2.example.net
CERT=vpn2.example.net.cer
KEY=vpn2.example.ne.key
ROUTER=<Router 2 IP Address>

cd $DIR/$DOMAIN

if [ -f $CERT ]; then
        echo -n "Uploading $DOMAIN certificate $ROUTER router..."
        scp -q $CERT $ROUTER:$CERT
        scp -q $KEY $ROUTER:$KEY
        rm $CERT $KEY
        echo "done!"
        exit 0
fi

On my routers, I have this script scheduled to run 30 minutes after the files are scheduled to be uploaded:

:if ([:len [/file find name=vpn1.example.net]] > 0) do={ 
    
    :put "Deleting Old Certificate"
        /certificate remove vpn1.example.net.cer_0
        :delay 1
    :put "Importing new Certificate"
        /certificate import file-name=vpn1.example.net.cer passphrase=""
        /certificate import file-name=vpn1.example.net.key passphrase=""
        :delay 1
    :put "Assigning certificate to SSTP Server"
        /interface sstp-server server set certificate=vpn1.example.net.cer_0
        :delay 1
    :put "Cleaning up files"
        /file remove vpn1.example.net.cer
        /file remove vpn1.example.net.key
    :put "Certificate installation complete"
}

Hi there,

Unfortunately metarouter is pretty much a forgotten feature by MikroTIk.

Currently MetaRouter can be used on

RB400, RB700 series except models with SPI flash, RB900 series except models with SPI flash, RB2011 boards
Listed PPC boards: RB1000, RB1100, RB1100AH and RB800.

In other words, CCR, RB3011, RB850Gx2, RB1100AHx4, etc which have enough cpu/storage/memory resources are not supported.

I am wondering; because the "first" validation method is manual (by creating a TXT record at your DNS provider) it seems the renewal process also needs a TXT DNS record validation.
After I successfully installed the certificates on my Mikrotik with the provided script I did a "certbot renew --dry-run" as to simulate a certifcate renewal. Certbot quickly prompts an error stating:
"The manual plugin is not working; there may be problems with your existing configuration. The error was: PluginError('An authentication script must be provided with --manual-auth-hook when using the manual plugin non-interactively.',). Skipping."

I do believe there has to be one of the 3 ways to authenticate the domain(s) for which the certificates are to be renewed (http-01, tls-sni-01 or dns-01). There are currently to my knowledge no plugins/addons/scripts in routerOS which provide these methods of authentication. Which basically means you have to re-do the TXT thing with your DNS provider and thus manually updating your certificates every 3 months.

Sob · Sun May 27, 2018 10:55 pm

It depends. Some DNS providers have API access for editing records, so if you use one of them, everything can be scripted and made fully automatic.

WarMaster · Mon May 28, 2018 2:49 pm

It depends. Some DNS providers have API access for editing records, so if you use one of them, everything can be scripted and made fully automatic.

A few do, most don't have a plugin available. However, the registration via the script is based on the manual TXT verification which in turn determines the way certbot stores the information regarding the particular certificate. So you'd have to fidget around with the certbot config to get this working properly. Furthermore; in the readme it is suggested the TXT verification is only once. I think this is false.

The topic is a request for ACME support which either suggests a request for http and/or tls-sni support. This script just isn't a solution for the proposed request.

Sob · Mon May 28, 2018 5:27 pm

As far as I know, domain verification lasts for a while, I think it was longer than 90 days for certificate, but eventually it has to be repeated, it's not valid forever.

DNS hosters without API access may be a problem for now, but it will get better, when people start to request this functionality (and Let's Encrypt is a good reason why they would do that). If yours doesn't want to do it, there are others to choose from. I wouldn't view this as THE problem. For now it's zero support for this in RouterOS. It's of course nice that I can do it with external Linux server, but if I don't have one already, it's highly impractical to get it just for this.

And when you think about it, it shouldn't be hard at all. Take the DNS method. RouterOS can already work with certificates, so it needs to extend it, so that you can request a certificate to be signed by LE. If you check some of the simpler clients (e.g. https://dehydrated.io/), there isn't too much to do. When it would be about to happen, there would be an event (hook), where you could put your own script to update DNS records. If the hoster's API would be based on http(s), then fetch tool in RouterOS should be all what's needed. It it would use standard DNS updates, RouterOS already has a tool for it, only so far it's limited to A records only. But that's the most of it already implemented, extending it to also support TXT records can't be hard. And that's it, happy end.

And actually, RouterOS could not only update records on remote server, it could BE the server. Not the full authoritative one with all bells and whistles, but only with basic functionality to serve TXT records, when you'd point _acme-challenge subdomain to it from main server using CNAME. Again, most of what's required for this is already in RouterOS.

Ok, I got a litle carried away with the last one, so forget it. But the rest is not hard. It's not 100% perfect solution for everyone, but it's important to get started.

I agree, it'd be great to have this integrated into RouterOS (so long as it had robust support for DNS validation, and not only HTTP). Until that happens, the script noted up-thread is a good starting point. I've forked it (like 75+ others) and made what I think are a few improvements:

Most importantly, updated both the script and the README to use RSA SSH keys rather than DSA keys--the latter are deprecated and won't work any more.
Allow the user to specify an alternate config file. I now have two switches to manage, this lets me deploy certs to both of them without keeping two copies of the script around.
Along with this change, removed the ability to specify all the connection parameters at the command line--you can't do "letsencrypt-routeros.sh USER HOST PORT KEY DOMAIN" any more. But you can create any number of config files to address this need.
Deploy the fullchain.pem file rather than cert.pem, to present a complete chain of trust
Implement a couple of sensible defaults (for SSH port and private key) if not set in the config file

What isn't changed is that this should work with any ACME client that has the capability to call a script after cert issuance, though it expects files to be in the places certbot places them by default (you can specify alternate locations in the config file if needed). And it should run on any Unix-y OS you want to run it on--I'm using a Ubuntu LXC on a Proxmox host, but it should be fine under any Linux distro, *BSD, on a Raspberry Pi, etc.
