How Can I Overcome SSL Certificate Validation Errors When Using WebRequest in HTTPS Connections?

Overcoming SSL Encryption Challenges for WebRequest in HTTPS Connections

Accessing content from HTTPS-encrypted websites using WebRequest can encounter obstacles if the encryption is not properly handled. When trying to make a request to such a site, errors may arise due to invalid SSL certificates or similar issues.

To address this, you can modify the code snippet you provided:

// Ignore any certificate validation errors
ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(AcceptAllCertifications);

// Execute the original code
Uri uri = new Uri(url);
WebRequest webRequest = WebRequest.Create(uri);
WebResponse webResponse = webRequest.GetResponse();
ReadFrom(webResponse.GetResponseStream());

The AcceptAllCertifications method defined below allows you to bypass SSL certificate validation errors:

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

By incorporating this fix, you can ensure that your program can successfully access content from HTTPS-encrypted websites, even if the SSL certificates are not considered valid by default.
