IdentityServer4 not working in production

I am using IdentityServer4 with React start project from ASP.NET Core 3.0. preview 4 and it works perfectly until I build the solution and try to run it from cmd prompt using the dotnet command. Everytime I start the application, it tells me that the key type is not specified.

I have tried various guides on generating certificates because I do not have any experience with certificates in .NET. I am mentioning this in case that the issue could be caused by an incorrect way of generating a certificate.

I have also tried to add the key type to the Appsettings.json, but I do not know what the type could be. I have been Google'ing all day for documentation on how to configure IdentityServer4 for deployment, but nobody seems to be having this issue or need any help generating the correct certificate.

I can run the application in Visual Studio, as long as I specify that it's a development environment.

When I switch to production or build the solution and run it from command prompt, the following stacktrace occurs:

If anybody can save me from this situation, I would be very grateful.

This is my first post, so if any more information is required, please feel free to ask me.

Post the code that you used to add signing credentials please. - Vidmantas Blazevicius
I have posted an answer explaining how I solved the issue. Thanks again for your assistance. :-) - Antheus_S

If you want to use *.pfx

"Key": {
  "Type": "File",
  "FilePath": "certificate.pfx",
  "Password": "password:!"
}

And read this thread if you have this error WindowsCryptographicException: Keyset does not exist

internal.cryptography.cryptothrowhelper+windowscryptographicexception keyset does not exist

So I was able to solve my issues using this piece of documentation: https://docs.microsoft.com/en-us/aspnet/core/security/authentication/identity-api-authorization?view=aspnetcore-3.0#example-deploy-to-azure-websites

I had to enable "Copy if newer" to the appsettings.json properties so that it would get copied to the build folder.

I also added the following to the appsettings.json file:

"IdentityServer": {
"Clients": {
  "Client": {
    "Profile": "IdentityServerSPA"
  }
},
"Key": {
  "Type": "Store",
  "StoreName": "My",
  "StoreLocation": "LocalMachine",
  "Name": "CN=SigningCertificate"
}
}

Now the Key.Type is specified, which means that we can now just add the following to the startup.cs:

// Configure IdentityServer4
var identityBuilder = services.AddIdentityServer();
identityBuilder.AddApiAuthorization<ApplicationUser, ApplicationDbContext>();

if (!Environment.IsDevelopment())
     identityBuilder.AddSigningCredentials();

I still do not understand why other people are not experiencing this issue, since I am not able to find any other threads on this issue and the regular way seems to work for everyone else. The only downside to this is that I need to install the certificate on the machine now instead of getting it as file.

Here is how I solved it in Docker for Blazor WebAssembly. My answer is mostly based on this thread. Keep in mind that, although it works, it may not be production-ready, nor safe. I know little about IdentityServer.

appsettings.json:

"IdentityServer": {
    //[...]

    "Key": {
      "Type": "File",
      "FilePath": "/path_to_certificate_here/server.pfx",
      "Password": "password_specified_later"
    }
  }

FilePath is where you physically placed your certificate (generated in next step of this answer). Password is being configured while generating certificate.

Generating certificate:

Source. This might not be production-ready either.

$ openssl genrsa 2048 > server_private.pem
$ openssl req -x509 -days 1000 -new -key server_private.pem -out server_public.pem
$ openssl pkcs12 -export -in server_public.pem -inkey server_private.pem -out server.pfx

Keep in mind that certificate will expire (-days attribute in 2nd command).

Working with Docker

There are some answers advising to include certificate in build folder or keep it with project source code. I personally don't think it's a good idea. I'm generating certificates manually on my server in separated folder, then I'm creating Docker volume pointing to folder where I placed them.

Beside the accepted answer, In case if someone wants to create their own SigningCredentials using the AsymmetricSecurityKey instead of the 'Key' configuration in appsettings.json, the following can also solve the problem.

  1. First define the RSA params in the xml file or store in the Application Resource file: e.g (working sample),
<RSAKeyValue>
    <Modulus>9+hZCiZrVpqe1t+Q4HOfzrmmkNkNPurX3btOva9Hdx1lIKV7ndeVGCq71plXhW78krXdcDSSeOEVf8W51/Qq0ai8Rg9P1XIcedVgIj7MiHZ+k/rcnq1Y9yg6d1DHXtlAJLasvhCc3o+9inXh2DAzllIxyy4FabS51dRyWDBMA2LS8kS3o5UdcVQYoY+B/9d8qVHmlbQNuao3NL/UqVo6UKnGidSjTQMyPkPJEmpul9C3Cn8Tm7zqKidk2A/obU5bmBFfivhPGoFnahYMs635LpitEPdJGQCfzcmLyE9y23cPyPzowkB/zsONCgWoxglst95vKRWgyXgBXAiSbKtaFQ==</Modulus>

</RSAKeyValue>
  1. Then, we can read the params using the RSA helper method to create the AsymmetricSecurityKey. I have created the following helper class for my project:
using System.Security.Cryptography;
public static class MyKeyStore
    {
        public static AsymmetricSecurityKey Key;

        static MyKeyStore()
        {
            var props = RSA.Create();
            props.FromXmlString(Resources.RsaProps);
            Key = new RsaSecurityKey(props);
        }
    }
  1. Modify the Startup.cs class and use the above helper class to generate the SigningCredentials. e.g.,
// configure IDS
 services.AddIdentityServer(options =>
            {
                // ...

            }).AddApiAuthorization<ApplicationUser, ApplicationDbContext>
            (options => { options.SigningCredential = new SigningCredentials(MyKeyStore.Key, SecurityAlgorithms.RsaSha512);});

Note that if you are wondering about a working example, i have recently used it in a demo project which is up and running and Azure at the moment. Here is the startup file and here is the complete project.

When using a .pfx file I got the following error:

Blazor - app.UseIdentityServer(); with .pfx key file - Unexpected character encountered while parsing number

I also had to enable my Azure App Service to access the certificate via Azure Cloud Shell. Complete guide here to avoid copied answers:
