Curl skipping SSL - Shell/Bash

When working with Curl, we often come across situations where SSL certificates are not properly configured or are self-signed. Curl by default strictly checks SSL certificates, which can sometimes lead to errors like "SSL Certificate Verification failed". However, sometimes we may need to skip SSL verification, especially during development and testing stages.

In such scenarios, we can use the curl -k or --insecure option to skip SSL verification.

Here's an example on how to use this option:

curl -k https://example.com

This will skip SSL certificate validation and will connect to the server. However, note that this option may compromise the security of the connection and should be used with caution.

Another option is to download the certificate manually and use it with the --cacert option:

curl --cacert /path/to/cert.pem https://example.com

This tells Curl to use the specified certificate for SSL verification.

In some cases, when dealing with older versions of Curl, the above options may not work. In such cases, we can disable SSL verification altogether using the --insecure option:

curl --insecure https://example.com

This option will disable all SSL verification, including the host's identity.

It is important to note that skipping SSL verification should only be done in development/testing environments and never in production environments.

In conclusion, Curl's SSL certificate verification is a crucial feature that ensures secure communication. However, in certain situations, SSL verification may need to be skipped or disabled temporarily, and this can be done through the various options available.
