我正在寻找从任何给定域名SSL证书的数据.例如,我想放在任何网址,例如“
https://stackoverflow.com”,我的代码首先检查是否存在SSL证书.如果是,那么我希望它能够提取证书的有效期. [我正在从DB读取Domainnames]

我需要创建一个Web服务来检查到期日.我该怎么实现呢？ – 我已经查找了许多不同的东西,如RequestCertificateValidationCallback和ClientCertificates等.
我可能完全错了(为什么我需要帮助),但是我会创建一个HTTPWebRequest,然后以某种方式请求客户端证书和特定元素的方式？
我试过提供@ SSL certificate pre-fetch .NET的例子,但是我得到forbitten 403错误.
任何帮助将不胜感激 – 谢谢.
解决方法
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);
为了运行这个,你需要添加system.security来引用.
