Related Epic #41990

The different flavors of Linux are the only place where --trust is not supported for dotnet dev-certs. We had an issue on openssl blocking this in the past that prevented dotnet-to-dotnet trust. Now that the issue has been solved and that distros are updating their openssl versions to newer versions without the original issue that was blocking us, we can consider adding support for trust across supported distros.

Our support Matrix looks as follows (taken from here):

OS Version
Alpine Linux 3.13+
CentOS 7+
Debian 10+
Fedora 32+
OpenSUSE 15+
Red Hat Enterprise Linux 7+
SUSE Enterprise Linux (SLES)] 12 SP2+
Ubuntu 16.04, 18.04, 20.04+

Open SSL status across versions

OS Version Open SSL Version on latest OS version
Alpine Linux 3.13+ 1.1.1k (on 3.13)
CentOS 7+ 1.1.1d (on 8.3)
Debian 10+ 1.1.1k (on 11)
Fedora 32+ 1.1.1k (on 34)
OpenSUSE 15+ 1.1.1d (on 15.2)
Red Hat Enterprise Linux 7+ TBD
SUSE Enterprise Linux (SLES)] 12 SP2+ 1.1.1d (on latest, based on assumptions from OpenSUSE)
Ubuntu 16.04, 18.04, 20.04+ 1.1.1k (on 21.04)

For the distros that don't meet the openssl version requirement, a new openssl version can be installed in most cases (at the users risk/judgement), either from an existing package available for the distro or downloading openssl and compiling it from source. I validated this across a few distros as follows:

  • Ubuntu: 21.04 already contains a new enough version.
  • Fedora: 34 already contains a new enough version.
  • Alpine: 3.13 already contains a new enough version.
  • CentOS: Installed open SSL by adding fedora 34 as a yum source and getting it from there.
  • OpenSUSE: There is an experimental package available for 1.1.1k in Open SUSE 15.2
  • SLES: I haven't tried, however I suspect the same package used for OpenSUSE works.
  • Debian: Tried with Bullseye which is on Hard Freeze and will be released likely this year. I only had to setup the apt sources for it to work. It already contains a new enough version.
  • RHEL: There's no way to download an ISO (AFAIK) without registering, which I don't want to do. I suspect the same I did on CentOS will work here.

Each distro that we want to support should be considered to have the cost of supporting and maintaining entire new OS, since we have to support specific environment variations and test functionality on each of them.

For each distro we need to support:

  • --clean to remove the trusted certificates.
  • --check to determine if the certificate is trusted in all the places we care about
    • Firefox
    • Edge/Chrome
    • dotnet runtime
  • --trust to apply the necessary changes in the environment to make the certificate trusted.

In addition to that, we need to make sure that all the tools and libraries we need are present on the OS, have the right version and are available on the path:

  • openssl (with a version equal or higher than 1.1.1h)
  • libnss3-tools (check for the presence of certutil)
  • firefox (check for firefox --version on the path)
  • edge (check for microsoft-edge --version)
  • chrome (check for google-chrome --version)

For each distro we need come up with a list of instructions to setup the machine and create a VM image we can leverage for regression testing. We need to capture the instructions for doing the following:

  • Install the base OS
  • Install Edge
  • Install Chrome
  • Install dotnet
  • Install new enough openssl version (if necessary)
  • Install libnss3-tools (certutil)

Prepare the VM to be shared with the team (we should be able to do so as described here

Once all the software is installed on the given distro, --trust, --check, --clean must work on 3 areas:

  • Firefox: Can be configured via an enterprise policy or via certutil, we need to determine the best way to do this. The user profile is in `~/,mozilla and we can find the default there.

  • Edge/Chrome: Can be configured via certutil at ~/.pki/certificates

  • dotnet runtime: Can be configured by dropping the certificate in the openssl folder.

Operation/Component Firefox Edge/Chrome dotnet runtime
--check look for a policy and a certificate in the right folder or use certutil against the profile database to ensure the right cert is trusted use certutil against the profile database to ensure the right cert is trusted check for a certificate file with the name aspnetcore-localhost-https-{sha256-certificate-hash}.pem in the openssl certificates folder
--trust either install an enterprise policy on the user profile or use certutil to modify the trust database for the profile db use certutil to modify the trust database export the certificate to a file in PEM format; copy the certificate to the openssl certificates directory with aspnetcore-localhost-https-{sha256-certificate-hash}.pem
--clean remove the enterprise policy and all certificates starting with aspnetcore-localhost-https- or use certutil to remove all certificates that match aspnetcore-localhost-https- from the profile database use certutil to remove all certificates that match aspnetcore-localhost-https- from the database remove all certificates that match aspnetcore-localhost-https- from the openssl certificates directory.

There are slight variations that we need to account for across distros. Ideally we don't want those things to show up in our code, since it will create a hard to maintain mess. To that matter, we will create a manifest for each distro/version with all the important details about the distro to drive all the operations and embed them in the dev-certs assembly.

When a command is run on Linux, we will try and recover the manifest by convention (<<distro>>.<<version>>.manifest.json) and will use the details there to drive the action.

The contents of the manifest are yet TBD, in its most simple form they can contain scripts that we can put on a temp file, chmod +x the file, run from the process and get a result back to determine the result of the operation. An alternative is to include details on per distro path locations and so on and have dotnet use that to drive the operation.

For example dotnet dev-certs https --trust --check can read the openssl directory location, get the current trusted certificate and check that there is a file with the right name at the openssl certs directory, read the cert and ensure it matches the one in the store.

Onboarding a new distro/version involves the following steps:

  • Create instructions to install all prerequisites.
  • Create and share a VHD that can be used for regression testing with the given instructions.
  • Create a manifest with the details for the distro and version and include it on the dotnet-dev-certs tool as an embedded resource.
  • Run a suite of manual tests we provide and perform a screen recording so that we can validate all scenarios are working.
  • Get another person to perform the same steps above to validate that the instructions are correct, complete and that everything works.

For reference, here are some scripts that cover many distros and that can be used as a starting point. The only one completely missing is Alpine, where the install experience just gives you a prompt and you have to run scripts to install everything else. In that case, we likely only need to figure out the work for trusting the cert by openssl since its very likely only used in container environments

I got bit by this, just today.

I'm trying to get OAuth 2.0 and OpenID to work between two local aspnetcore services, using IdentityServer4, and I'm getting certificate chain errors.

https://stackoverflow.com/questions/67910658/how-do-i-trust-dotnets-dev-cert-in-linux

I can't speak to how many others are trying to do what I am, but I at least am having this issue, and it would be nice if the problem was fixed.

This worked nicely for me:

#7246 (comment)

I'm on Ubuntu 20.04.

I was having trouble getting Identity authentication to work on our project, that said the docs really need an update. I spent a ridiculous amount of time not understanding what I was doing wrong, in fact I still can't get Firefox on Ubuntu 20.04 to fully trust the certs (the top-left lock still shows an exclamation mark but the authentication now works, Chrome seems to be fine).

Here are the links to the docs:

https://docs.microsoft.com/en-us/aspnet/core/security/enforcing-ssl?view=aspnetcore-5.0&tabs=visual-studio#ubuntu-trust-the-certificate-for-service-to-service-communication

https://docs.microsoft.com/en-us/aspnet/core/security/enforcing-ssl?view=aspnetcore-5.0&tabs=visual-studio#trust-https-certificate-on-linux

https://docs.microsoft.com/en-us/dotnet/core/additional-tools/self-signed-certificates-guide#with-dotnet-dev-certs

There should at least be a note on there that says there is known issue with dotnet dev-certs on Linux and redirect to a workaround, it would save a lot of time for a lot of newbies like me.

I got it working for Manjaro with the following script. I didn't do it for FireFox because I mainly use Chromium, so you may have to figure that part out.

# Create cert

# Export cert to current directory

ok, let me rephrase this. this is why you should avoid microsoft products or services at all cost because it always results in monopolistic behavior. First the claim is "cross platform" and then they make you sneakily fail on other platforms by including some hidden nasties. They will never improve.

@HummingMind

What are you going on about? This issue exists specifically to address the problem and develop a solution. Microsoft should somehow be avoided because this didn't make it into .NET 7 but will be in .NET 8? That is absurd. Did you provide any possible solutions to them instead of conspiracy theories?

Could we get some distros available for .NET 7 and/or having it with a « preview » flag so we know that we can face some limitations and wait for .NET 8 to stabilize the whole implementation ? We will be able to use it for testing purpose and give you some feedbacks during .NET 8 dev timeframe.

@YohanSciubukgian unfortunately it was/is too late in the development cycle to get this into 7.0.0, but it's something on the list for .NET 8 which you could try previews of once available.

(Using Windows with Linux Containers via Docker Deskop + WSL2. Testing with 2 simple aspnet core APIs in docker-compose, 1 making an https call to the other via HttpClient.)

I've gone down this rabbit hole for a couple days now. Even if you skip the dotnet dev-certs tools and use openSSL to create a compatible dotnet localhost dev-cert with the special markers, get that .pfx trusted in Windows, and then get the accompanying .crt loaded into and trusted by the container at runtime, API --> API communication is still fundamentally broken.
(Keep in mind that both test APIs are using the same certificate files and that I can successfully validate this cert chain in both the Windows host and the container using 'dotnet dev-certs https --check --trust' and 'openssl verify' etc.)

In short, is it true to state that we can get host-to-container SSL trust to work (i.e. chrome website and direct api call), but not for container-to-container trust (i.e. API calling another API)?

bartonjs commented Mar 2, 2023

The general problem is that each distro's way of updating system trust is different, particularly with regard to getting it to apply to all tools. That's the reason that we don't enable writing to the LocalMachine\Root store on Linux.

If the dev-certs tool wants to take the distro into account and have distro-specific variance, that seems reasonable to me (off the top of my head). I'd defer here to @blowdart for trying to balance UX with predictability and maintainability.

ghost commented Mar 2, 2023

Yeah, I thought that at first and had to retract that statement after thinking better. However, students will hop over to Linux as I once did and want to develop there. The certificate is just to help prevent a scare and bypass the browser security prompt. Little things like that lead up to phycological blocks in creativity. Even I still get spooked when Visual Studio or Rider prompts to add to the firewall, lol. It's a tick.

It doesn't need to go in the root stores, just the users' profiles. Although I don't know about Dotnet-to-Dotnet situations.

Just a heads up, if anyone faces the same issue I had (Linux Mint)

Everything was working fine for quite a while after following the above instructions. One day, however, Edge and Chrome just stopped trusting the cert. Firefox still worked.

After reading this guide: https://learn.microsoft.com/en-gb/aspnet/core/security/enforcing-ssl?view=aspnetcore-7.0&tabs=visual-studio%2Clinux-ubuntu#linux-certificate-not-trusted

I was given the clue that somehow the file permissions on /usr/local/share/ca-certificates/aspnet/https.crt had been reduced to root only. Running sudo chmod 644 /usr/local/share/ca-certificates/aspnet/https.crt fixed the issue for me.

--
Further to the above Chrome/Edge broke again, what I found that works now is to ONLY "P" in NSSDB, i.e. run
certutil -d sql:$HOME/.pki/nssdb -A -t "P,," -n localhost -i ./localhost.crt
and not this one
certutil -d sql:$HOME/.pki/nssdb -A -t "C,," -n localhost -i ./localhost.crt

What worked for me was (on Kali Linux, but it should work on Debian and Ubuntu as well):

sudo apt install mkcert
cd /usr/local/share/ca-certificates
mkcert -install

If you have localhost.crt in the /usr/local/share/ca-certificates directory, then remove it with:

sudo rm -rf localhost.crt

@amcasey here is my earlier attempt to make this command work on Linux: #33279. It probably has code you can use. I did get some feedback against using a CA certificate: https://twitter.com/tomdeseyn/status/1390590053953462272.

You probably also want .NET itself to trust the development certificate so it can talk to .NET services in an ASP.NET Aspire orchestration.

That's exactly the situation that I'm currently facing. The new preview of Aspire (Preview 6) requires a cert all the way. I can't get the dev cert to be trusted on my Fedora 40 machine. Any help regarding this would be greatly appreciated.

@tmds Doh! I did try it, but didn't restart my machine. After the restart it works flawlessly, sorry for the fuss.
Thanks for this tool 🥰
