When interfacing with secured web services, SSL/TLS verification is a crucial step to ensure the authenticity of the server’s certificate. However, in some development or testing scenarios, you might need to disable SSL verification in Curl. This article provides a guide on how to do so using different methods while warning of the security risks involved.

Disabling SSL Verification in Curl Command
By default, Curl attempts to verify the SSL certificate of the target server. To disable the SSL verification, you can use either CURL parameters or modify the .curlrc configuration file.
Using CURL Parameters
To disable SSL verification using Curl parameters, you can pass the ‘-k‘ or ‘--insecure‘ option in your command.
curl -k https://example.com
This way, Curl will perform “insecure” SSL connections and transfers without checking the certificate.
Using .curlrc File
If you want to persistently disable the SSL verification for all Curl commands, you can use the .curlrc file. Simply add the following line:
insecure
This line should be placed in your home directory within the .curlrc file. Every time you use Curl, it will automatically apply the insecure option.
Understanding the Security Implications
Disabling SSL verification can leave your data transfers vulnerable to man-in-the-middle attacks. Always ensure to re-enable SSL verification in production environments to maintain security.
Conclusion
To disable ssl verification in Curl, you can use either command-line parameters or the .curlrc configuration file. While this can be useful in some scenarios, be mindful not to compromise security, especially in production environments where data integrity and protection are paramount.
