How Can I Use WebRequest to Access HTTPS URLs Despite SSL Certificate Issues?

Using WebRequest with HTTPS: Overcoming SSL Encryption Challenges

When working with URLs, it's common to encounter both HTTP and HTTPS protocols. HTTPS, utilizing SSL encryption, adds an extra layer of security to your communication. However, this can present challenges when using WebRequest.

Issue:

A user encountered an issue when accessing an HTTPS URL using the following code:

Uri uri = new Uri(url);
WebRequest webRequest = WebRequest.Create(uri);
WebResponse webResponse = webRequest.GetResponse();
ReadFrom(webResponse.GetResponseStream());

Analysis:

In certain cases, this code may fail if the URL points to a site with an invalid SSL certificate.

Solution:

To resolve the issue and allow access to SSL-encrypted sites, implement the following steps:

ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(AcceptAllCertifications);

public bool AcceptAllCertifications(object sender, System.Security.Cryptography.X509Certificates.X509Certificate certification, System.Security.Cryptography.X509Certificates.X509Chain chain, System.Net.Security.SslPolicyErrors sslPolicyErrors)
{
    return true;
}

These two lines ignore any SSL certification problems, effectively allowing access to the target site regardless of certificate validity.

After implementing this solution, the provided code should be able to successfully read content from both HTTP and HTTPS URLs.
