Does anyone know where to set the passphrase for the PEM file that is configured in the Push Notification Plugin for Craft CMS?
I have created a new app and set the Certification Location to the PEM file location. I have tested on the server to confirm that the certificate and key files work. However, when I try to send a new alert -- I get the following error:
stream_socket_client(): Unable to set private key file
Which I'm sure is due to the fact that I haven't told it what the passphrase is. However, I can't find any documentation that explains where to put this configuration setting.
Any help is greatly appreciated.
