Use of LetsEncrypt certificate in Blazor Webassembly project published on ISS in Windows Server

Question

I'm following this solution to use certificate for my Webassembly project. InvalidOperationException: Key type not specified. Microsoft.AspNetCore.ApiAuthorization.IdentityServer.ConfigureSigningCredentials.LoadKey()

If I use a self certificate it will works fine but I need of a C.A. certificate and I created it with Let's Encrypt. How can I add LetsEncrypt certificate into appsettings.json? My new certificate hasn't password so the code below not works.

     "IdentityServer": {
    "Key": {
      "Type": "File",
      "FilePath": "C:\cert.pfx",
      "Password": "password123"
    }
  }

Can someone help me, please?

Answer 1

I solved by creating a "new certificate with advanced options" instead of "create new certificate" through Let's Encrypt tool, in this way I can set the password required to use certificate in my .NET Core project.
