Question

我们正在将IdentityServer4与.NET核心Web应用程序一起使用（＆＃34; http://docs.identityserver.io/en/release/quickstarts/0_overview.html＆＃34;）。我们已将AddDeveloperSigningCredential替换为AddSigningCredential(CreateSigningCredential())。因为我们不能将AddDeveloperSigningCredential用于生产环境，因为生产需要被一些持久性密钥材料所取代。我们是IdentityServer4的新手，我们的问题是，以下方法是否可以在生产环境中创建签名凭据？或者我们是否需要对此进行一些更改？

这是我们的startup.cs文件：

public void ConfigureServices(IServiceCollection services)
{
    services.AddSingleton<IConfiguration>(Configuration);

    //connection string
    string connectionString = Configuration.GetConnectionString("IdentityServer");

    var migrationsAssembly = typeof(Startup).GetTypeInfo().Assembly.GetName().Name;

    services.AddIdentityServer().AddDeveloperSigningCredential
    .AddSigningCredential(CreateSigningCredential())
    // 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 SigningCredentials CreateSigningCredential()
{
    var credentials = new SigningCredentials(GetSecurityKey(), SecurityAlgorithms.RsaSha256Signature);

    return credentials;
}
private RSACryptoServiceProvider GetRSACryptoServiceProvider()
{
    return new RSACryptoServiceProvider(2048);
}
private SecurityKey GetSecurityKey()
{
    return new RsaSecurityKey(GetRSACryptoServiceProvider());
}

Answer 1

以下是使用X509自签名证书的简单方法。

使用自签名证书用于与IdentityServer4进行令牌签名的一种方法是将证书与应用程序一起存储在“wwwroot”文件夹下。

public void ConfigureServices(IServiceCollection services)
{
        .....other code .....

        var fileName = Path.Combine(env.WebRootPath, "YOUR_FileName" );            

        if (!File.Exists(fileName))
        {
            throw new FileNotFoundException("Signing Certificate is missing!");
        }

        var cert = new X509Certificate2(fileName, "Your_PassPhrase" );

        services.AddIdentityServer().AddSigningCredential(cert)

        ...other code.....
}

Answer 2

这里是一个gist，它应该对使用asp.net core 2.x的Ids4有所帮助。

它包含一个RsaKeyService类，可以将其注入服务提供者，例如：

var rsa = new RsaKeyService(Environment, TimeSpan.FromDays(30));
services.AddTransient<RsaKeyService>(provider => rsa);

这可以确保在重新生成新密钥之前，最多只能使用30天RSA密钥。

要使用该密钥，可以调用rsa.GetKey()，并注册为签名证书，请使用：

builder.AddSigningCredential(rsa.GetKey());

我没有看到任何持续存在的东西，所以我不得不说，这不合适。我在这里提供了一个加载证书的例子：

How we can replace AddDeveloperSigningCredential on AWS Serverless Lambda environment?

我建议采用这种方法。您可以将证书部署在OS证书库中，作为文件或作为应用程序本身的嵌入式资源。

ETA：由于您已经说过X509证书不在考虑范围内（有兴趣知道原因），因此您需要自己向RsaSecurityKey提供RSAParameters。

请参阅此处了解Microsoft.IdentityModel.Tokens库中使用的测试数据：
