.Net SqlConnection，服务器身份验证和证书锁定

如何在使用s SqlConnection时锁定证书？从SqlConnection Connection String Parameter Keywords & Values，我知道我可以设置Encrypted到true强制（鼓励？）使用SSL/TLS。.Net SqlConnection，服务器身份验证和证书锁定

但是，为了获得证书，我相信我们需要使用 ServicePointManager（以下示例代码由ArneVajhøj提供，用于HTTP/HTTPS）。我不清楚如何将PinCertificate（从ServicePointManager）连线到SqlConnection。

更新：与microsoft.public.dotnet.languages.csharp上的ArneVajhøj交谈，似乎无法对连接进行所需的控制。 Vajhøj提供了链接Encrypting Connections to SQL Server。

public static void Main(string[] args) 
{ 
    ServicePointManager.ServerCertificateValidationCallback = PinCertificate; 
    WebRequest wr = WebRequest.Create("https://www.google.com/"); 

    wr.GetResponse(); 
} 

public static bool PinCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) 
{ 
    byte[] chash = certificate.GetCertHash(); 

    StringBuilder sb = new StringBuilder(chash.Length * 2); 
    foreach (byte b in chash) 
    sb.AppendFormat("{0:X2}", b); 

    // Verify against known SHA1 thumb print of the certificate 
    String hash = sb.ToString(); 
    if (hash != "C1956DC8A7DFB2A5A56934DA09778E3A11023358") 
    return false; 

    return true; 
}

在VB.NET证书验证的例子：http://social.msdn.microsoft.com/forums/en-US/netfxnetcom/thread/ 5f5af31c-74f2-4147-8b70-e9e8ec03c76a。应该很容易转换。 – 2012-01-01 06:21:59

MSDN示例使用“ServicePointManager”和“ServerCertificateValidationCallback”（调用“MyCertValidationCb”）。它与我发布的样本没有什么不同。我仍然不清楚如何将'ServerCertificateValidationCallback'连接到'SqlConnection'。 – jww 2012-01-01 06:53:00

怎么是这样的：

System.Net.ServicePointManager.ServerCertificateValidationCallback = New RemoteCertificateValidationCallback(AddressOf ValidateCertificate) 

Private Function ValidateCertificate(ByVal sender As Object, ByVal certificate As X509Certificate, ByVal chain As X509Chain, ByVal sslPolicyErrors As SslPolicyErrors) As Boolean 
    'Return True to force the certificate to be accepted. 
    Return True 
End Function
