While attempting to clean up our project dependencies, composer is failing with the errors:
The "https://packagist.drupal-composer.org/packages.json" file could not be downloaded: SSL operation failed with code 1. OpenSSL Error messages:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
Failed to enable crypto
failed to open stream: operation failed
https://packagist.drupal-composer.org could not be fully loaded, package information was loaded from the local cache and may be out of date
This is happening on a vagrant CentOS 7 box.
