Tip #41: Did you know... establishing a remote connection to a IIS server with self-issued certificate will require a certificate validation delegate?
Either through WMSvc or through your own script, whenever you try to establish a connection with a remote server, which doesn’t provide a trusted certificate you need to provide a delegate for this certificate validation check to validate untrusted certificates.
The signature for this delegate is as follows
Namespace: System.Net.Security
Assembly: System (in System.dll)
public delegate bool RemoteCertificateValidationCallback(
Object sender,
X509Certificate certificate,
X509Chain chain,
SslPolicyErrors sslPolicyErrors
)
Thus, to accept ALL server certificates, you will need to set the callback of ServicePointManager to validate a server certificate in the following manner:
ServicePointManager.ServerCertificateValidationCallback = RemoteCertificateValidationCallbackFlag;
bool RemoteCertificateValidationCallbackCheck(
Object sender,
X509Certificate certificate,
X509Chain chain,
SslPolicyErrors sslPolicyErrors
)
{
return true;
}
For the official MSDN documentation on this delegate refer to RemoteCertificateValidationCallback Delegate and ServicePointManager.ServerCertificateValidationCallback Property
