Question

I would like to communicate with the Apple Push Notification Service from a PHP script.
But I keep getting following error:

Warning: stream_socket_client(): Unable to set private key file

I have a .pem-file which looks like this:

-----BEGIN CERTIFICATE-----
     Encrypted String
-----END CERTIFICATE-----
     Bag Attributes
     friendlyName: ...
     localKeyID: ...
     Key Attributes: ...
-----BEGIN RSA PRIVATE KEY-----
     Proc-Type: ...
     DEK-Info: ...

     Encrypted String
-----END RSA PRIVATE KEY-----

I am running the PHP script from sudo. It can find my .pem file, because if I remove it, I get a "handshake failure" error instead.

What could be wrong here?

Answer 1

I got it working. It turns out I exported my private key which I generated for the push notifications instead of the corresponding certificate.
