.net core 自颁发ssl证书，及客户端证书验证

openshell 颁发证书：

先下载 openshell，下载地址：https://slproweb.com/products/Win32OpenSSL.html

openssl genrsa -out server.key 2048
openssl x509 -req -in server.csr -out server.crt -signkey server.key -days 36500
openssl pkcs12 -export -in server.crt -inkey server.key -out server.pfx 

appsettings.json 配置文件：

　　增加  kestrel 配置https及证书文件；

{
  "Kestrel": {
    "Endpoints": {
      "HttpsInlineCertAndKeyFile": {
        "Url": "https://*:5433",
        "Certificate": {
          "Path": "./certs/server.pfx",
          "Password": "123456"
        }
      }
    }
  }
}

//配置客户端连接时必需选择证书,不对证书验证
services.Configure<KestrelServerOptions>(options =>
{
    options.ConfigureHttpsDefaults(options =>
    {
        options.ClientCertificateMode = ClientCertificateMode.RequireCertificate;
        options.ClientCertificateValidation = (_, _, _) => true;
    });
});

//证书认证
services.AddAuthentication(CertificateAuthenticationDefaults.AuthenticationScheme)
    .AddCertificate(options =>
    {
        options.AllowedCertificateTypes = CertificateTypes.All;
        options.ValidateCertificateUse = false;
        options.ValidateValidityPeriod = false;
        options.ChainTrustValidationMode = System.Security.Cryptography.X509Certificates.X509ChainTrustMode.CustomRootTrust;

        options.Events = new CertificateAuthenticationEvents
        {
            OnCertificateValidated = context =>
            {
                //验证客户端证书指纹
                var thumbprints = context.HttpContext.RequestServices.GetRequiredService<IOptionsMonitor<ThumbprintOptions>>();
                if (thumbprints.CurrentValue.Contains(context.ClientCertificate.Thumbprint))
                {
                    var claims = new[]
                        {
                        new Claim(
                            ClaimTypes.NameIdentifier,
                            context.ClientCertificate.Subject,
                            ClaimValueTypes.String, context.Options.ClaimsIssuer),
                    };

                    context.Principal = new ClaimsPrincipal(
                        new ClaimsIdentity(claims, context.Scheme.Name));
                    context.Success();
                }
                else
                {
                    context.Fail("证书错误");
                }
                return Task.CompletedTask;
            }
        };
    });

管道中使用授权认证：

　　//将http请求重置到 https
　　app.UseHttpsRedirection();

　　app.UseCertificateForwarding();

　　app.UseAuthentication();

　　app.UseAuthorization();

控制器中增加认证

[Authorize(AuthenticationSchemes = CertificateAuthenticationDefaults.AuthenticationScheme)]
public class textController : ControllerBase
