获得.NET SSL证书 [英] get ssl certificate in .net

问题描述

我期待从任何给定的域名的SSL证书获取数据。例如，我希望把任何网站地址例如 http://stackoverflow.com 和我的code会首先检查是否SSL证书存在。如果是的话那么我想它拉出证书的失效日期。 [我从DB读DOMAINNAMES]
例如： http://www.digicert.com/help/

我需要创建一个Web服务来检查失效日期。我怎么才能实现它？ - 我已经看过了不同的东西，如RequestCertificateValidationCallback和ClientCertificates等

负荷。

我可能是完全错误的（所以为什么我需要帮助），但我想创建一个HttpWebRequest和然后以某种方式要求客户端证书和具体内容呀？

我试过的例子提供@ SSL证书pre取.NET ，但我正在逐渐forbitten 403错误。

任何帮助将是非常美联社preciated - 谢谢

解决方案

 使用System.Security;
    使用System.Security.Cryptography;
    使用System.Security.Cryptography.X509Certificates;    //做的WebRequest获取有关安全网站信息
    HttpWebRequest的要求=（HttpWebRequest的）WebRequest.Create（https://mail.google.com）;
    HttpWebResponse响应=（HttpWebResponse）request.GetResponse（）;
    response.Close（）;    //获取SSL证书并将其分配给一个X509Certificate对象
    x509证书证书= request.ServicePoint.Certificate;    //通过传递到它的构造转换为X509Certificate到X509Certificate2对象
    X509Certificate2 cert2 =新X509Certificate2（CERT）;    串CN = cert2.GetIssuerName（）;
    字符串cedate = cert2.GetExpirationDateString（）;
    字符串cpub = cert2.GetPublicKeyString（）;    //显示证书对话框
    X509Certificate2UI.DisplayCertificate（cert2）;
 

为了运行这个，你需要添加system.security参考。

i am looking to get the data from any given domain names SSL certificate. For example I want to put in any website address e.g. "http://stackoverflow.com" and my code would firstly check if an SSL certificate exists. If it does then I want it to pull out the expiry date of the certificate. [ i am reading Domainnames from DB ] Example :http://www.digicert.com/help/

i need to create a web service to check expiry date. how can i implement it?? - I have looked up loads of different things such as RequestCertificateValidationCallback and ClientCertificates etc.

I could be completely wrong (hence why I need help) but would I create a HTTPWebRequest and then somehow request the client certificate and specific elements that way?

i tried the example provided @SSL certificate pre-fetch .NET , but i am getting forbitten 403 error.

Any help would be much appreciated - Thank you.

解决方案

    using System.Security;
    using System.Security.Cryptography;
    using System.Security.Cryptography.X509Certificates;

    //Do webrequest to get info on secure site
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://mail.google.com");
    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    response.Close();

    //retrieve the ssl cert and assign it to an X509Certificate object
    X509Certificate cert = request.ServicePoint.Certificate;

    //convert the X509Certificate to an X509Certificate2 object by passing it into the constructor
    X509Certificate2 cert2 = new X509Certificate2(cert);

    string cn = cert2.GetIssuerName();
    string cedate = cert2.GetExpirationDateString();
    string cpub = cert2.GetPublicKeyString();

    //display the cert dialog box
    X509Certificate2UI.DisplayCertificate(cert2);

in order to run this you need to add system.security to reference.
