We are using IdentityServer4("http://docs.identityserver.io/en/release/quickstarts/0_overview.html") with EntityFrameworkCore to store operational and configuration data. To add signing credentials we are using x509 self signed certificates. We have used following command to create x509 self signed certificate:makecert -r -pe -n "CN=CertName_IdentityServer" -b 01/01/2015 -e 01/01/2039 -eku 1.3.6.1.5.5.7.3.3 -sky signature -a sha256 -len 2048 identityserver.cer. And add this certificate as embedded source in the solution.
Here is our startup.cs file:
public void ConfigureServices(IServiceCollection services)
{
services.AddSingleton<IConfiguration>(Configuration);
//connection string
string connectionString = Configuration.GetConnectionString("IdentityServer");
var migrationsAssembly = typeof(Startup).GetTypeInfo().Assembly.GetName().Name;
ConfigureSigningCerts(services);
services.AddIdentityServer()
// this adds the config data from DB (clients, resources)
.AddConfigurationStore(options =>
{
options.ConfigureDbContext = builder =>
builder.UseSqlServer(connectionString,
sql => sql.MigrationsAssembly(migrationsAssembly));
}) // this adds the operational data from DB (codes, tokens, consents)
.AddOperationalStore(options =>
{
options.ConfigureDbContext = builder =>
builder.UseSqlServer(connectionString,
sql => sql.MigrationsAssembly(migrationsAssembly));
// this enables automatic token cleanup. this is optional.
options.EnableTokenCleanup = true;
options.TokenCleanupInterval = 30;
});
}
private static void ConfigureSigningCerts(IServiceCollection services)
{
var assembly = typeof(Startup).GetTypeInfo().Assembly;
/*
* IdentityServer.WebApi\
* Certificates\
* identityserver.cer
*
* {assembly name}.{directory}.{file name}
*/
using (Stream resource = assembly.GetManifestResourceStream("IdentityServer.WebApi.Certificates.identityserver.cer"))
using (var reader = new BinaryReader(resource))
{
var signingCert = new X509Certificate2(reader.ReadBytes((int)resource.Length));
var keys = new List<SecurityKey>();
if (signingCert == null) throw new InvalidOperationException("No valid signing certificate could be found.");
var signingCredential = new SigningCredentials(new X509SecurityKey(signingCert), "RS256");
services.AddSingleton<ISigningCredentialStore>(new DefaultSigningCredentialsStore(signingCredential));
var validationCredential = new SigningCredentials(new X509SecurityKey(signingCert), "RS256");
keys.Add(validationCredential.Key);
services.AddSingleton<IValidationKeysStore>(new DefaultValidationKeysStore(keys));
}
}
When we execute the application on local host discovery endpoint works fine but when called connect/token endpoint we got the following error message:

It looks like if you use a file you may need to do an additional step and assign a password to allow the private key to be accessed.
This should hopefully help: How to create a self signed certificate with the private key inside in a file in one simple step?
An alternative is to generate the cert in the local machine certificate store and then export it via the certificate management MMC snap-in.
