RemoteCertificateValidationCallback Delegate

Verifies the remote Secure Sockets Layer (SSL) certificate used for authentication.

Namespace:  System.Net.Security
Assembly:  System (in System.dll)

JScript does not support delegates.

Parameters

sender
Type: System.Object

An object that contains state information for this validation.

certificate
Type: System.Security.Cryptography.X509Certificates.X509Certificate

The certificate used to authenticate the remote party.

chain
Type: System.Security.Cryptography.X509Certificates.X509Chain

The chain of certificate authorities associated with the remote certificate.

sslPolicyErrors
Type: System.Net.Security.SslPolicyErrors

One or more errors associated with the remote certificate.

Return Value

Type: System.Boolean
A Boolean value that determines whether the specified certificate is accepted for authentication.

The delegate's sslPolicyErrors argument contains any certificate errors returned by SSPI while authenticating the client or server. The Boolean value returned by the method invoked by this delegate determines whether the authentication is allowed to succeed.

This delegate is used with the SslStream class.

The following code example implements a method that is invoked by an instance of the RemoteCertificateValidationCallback class. If there are validation errors, this method displays them and returns false, which prevents communication with the unauthenticated server.
