Solution for SSL certificate issue with Cisco Umbrella and Composer for PHP Packages.

Problem

If you are getting an error like this:

curl error 60 while downloading https://repo.packagist.org/p2/onelogin/php-saml.json: SSL certifi
 cate problem: unable to get local issuer certificate

and you have Cisco Umbrella Security running, then you are probably getting blocked by a rule.

Solution

Either configure Cisco Umbrella to allow packages from packagist.org

Or if you don’t have access to that. Hack your box and turn off the service running on your Windows box and try again, then restart the service when you are done to re-enable the security.

Happy Coding.
