如何从客户端应用程序运行Web服务的服务器的SSL证书？ - C＃.NET [英] How to get the SSL certificate of a server running a web service from the client app? - C# .NET

问题描述

我已经写在.NET 2.0的客户端程序，连接到Web服务。 我使用的Visual Studio来生成SoapHttpClientProtocol派生的类， 生成每一个方法就好了，一切正常。

I have a client program written in .NET 2.0, that connects to the web service. I used Visual Studio to generate a class derived from SoapHttpClientProtocol, every method was generated just fine, everything is working.

不过 - 网络服务正在运行只能通过HTTPS，所以我只是想知道，我怎么能得到服务器的证书的一个X509Certificate实例

But - the web service is running only through HTTPS, so I was just wondering, how could I get an X509Certificate instance of the server's certificate.

我知道这个框架做服务器的证书的验证透明的，所以我不需要去关心我的code中的证书验证，但我如果我需要阅读证书的序列号？

I know the Framework does the validation of the server's certificate transparently, so I dont need to care of the certificate validation in my code, but I what if I needed to read the certificate's serial number?

在SoapHttpClientProtocol基类似乎只有成员/方法的客户端证书。

The SoapHttpClientProtocol base class seems to have only members/methods for client certificates.

推荐答案

您挂钩到<一个href="http://msdn.microsoft.com/en-us/library/system.net.servicepointmanager.servercertificatevalidationcallback.aspx"相对=nofollow> ServicePointManager.ServerCertificateValidationCallback 。您的回调将与服务器的<一个被调用href="http://msdn.microsoft.com/en-us/library/system.security.cryptography.x509certificates.x509certificate.aspx"相对=nofollow> X509证书 ，然后你可以检查任何你喜欢的就可以了，像<一个href="http://msdn.microsoft.com/en-us/library/system.security.cryptography.x509certificates.x509certificate.issuer%28VS.80%29.aspx"相对=nofollow> 发行人 和<一href="http://msdn.microsoft.com/en-us/library/system.security.cryptography.x509certificates.x509certificate.getserialnumberstring%28VS.80%29.aspx"相对=nofollow> 的SerialNumber 。

You hook into the ServicePointManager.ServerCertificateValidationCallback. Your callback will be invoked with the server's X509Certificate and you can check anything you like on it, like the Issuer and SerialNumber.
