Unable to load client certificate private key file

问题

I am unable to create Apple Push Notification cert files. When I test .pem files I get an error.

openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert pushapp_cert_dev.pem -key pushapp_key_dev.pem

will give an error:

unable to load client certificate private key file 140735327015760:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:703:Expecting: ANY PRIVATE KEY

I am following these instructions: https://github.com/raix/push/wiki/iOS-Micro-Walkthrough

pushapp_cert_dev.pem

-----BEGIN CERTIFICATE-----
MIIFiTCCBHGgAw...ff6eVQDZV4=
-----END CERTIFICATE-----

pushapp_key_dev.pem

Both files are in the same location.

When I created the .pem file, I simply needed to enter passphrase (min 4 char) when prompted. First, I just skipped it because I didn't want to create passphrase. It doesn't give any error or otherwise inform that passphrase is required and it actually creates a non working .pem file.
