How to Ignore SSL Certificate Errors in C#?

Handling SSL Certificate Errors in C#

Connecting to a web service can sometimes trigger SSL/TLS certificate validation errors. This often happens if the server certificate lacks a valid signature or a trust relationship problem exists.

Workaround for Certificate Validation Issues:

One solution is to implement a custom certificate validation callback. This allows you to override the default validation and proceed with the connection even if errors are detected. This is done by creating a handler that always returns true:

ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;

Adding this code will effectively ignore certificate validation errors and allow the connection to continue.

Important Security Consideration:

Disabling certificate validation significantly weakens your system's security. Use this method only after careful consideration of the risks involved. It's crucial to understand that bypassing this check leaves your application vulnerable to man-in-the-middle attacks and other security threats. Only employ this approach if you fully understand the implications and have thoroughly assessed the security risks.
