Validate Certificates
You can validate a host’s certificate before creating a secure connection in order to make sure that the host’s certificate is valid or a trusted party. You can also check if the certificate has expired.
Example
HTTPS https = new HTTPS();
https.CertificateValidation += new HTTPS.CertificateValidationDelegate(https_CertificateValidation);
https.CertificateValidation += new HTTPS.CertificateValidationDelegate(https_CertificateValidation);
private void https_CertificateValidation(object sender, CertificationEventArgs e)
{
if (e.SslPolicyErrors == System.Net.Security.SslPolicyErrors.None)
{
//Valid certificate. You can go on further and check the following fields
//to make sure that the certificate is valid
string expDate = e.Certificate.GetExpirationDateString();
string effDate = e.Certificate.GetEffectiveDateString();
string issName = e.Certificate.GetIssuerName();
}
else
{
//Invalid Certificate
e.Cancel = true;
}
{
if (e.SslPolicyErrors == System.Net.Security.SslPolicyErrors.None)
{
//Valid certificate. You can go on further and check the following fields
//to make sure that the certificate is valid
string expDate = e.Certificate.GetExpirationDateString();
string effDate = e.Certificate.GetEffectiveDateString();
string issName = e.Certificate.GetIssuerName();
}
else
{
//Invalid Certificate
e.Cancel = true;
}
}
