Hi Emanuel,

Unfortunately we cannot provide support on this, you can refer to pem's documentation or post on a forum like stack overflow.

Good luck,

Shahab

this one helped me:

# Make sure terminal refers your correct certificate path.
$ cd ~/Desktop/

# Ask system administrator to open if its not connected 
$ telnet gateway.sandbox.push.apple.com 2195

Trying 17.110.227.35...
Connected to gateway.sandbox.push-apple.com.akadns.net.

Escape character is '^]'.

# Convert .cer to .pem
$ openssl x509 -in aps_development.cer -inform der -out PushCert.pem

# Convert .p12 to .pem. Enter your pass pharse which is the same pwd that you have given while creating the .p12 certificate. PEM pass phrase also same as .p12 cert.  
$ openssl pkcs12 -nocerts -out PushKey1.pem -in pushkey.p12

Enter Import Password:

MAC verified OK

Enter PEM pass phrase:

Verifying - Enter PEM pass phrase:

# To remove passpharse for the key to access globally. This only solved my stream_socket_client() & certificate capath warnings.
$ openssl rsa -in PushKey1.pem -out PushKey1_Rmv.pem

Enter pass phrase for PushChatKey1.pem:

writing RSA key

# To join the two .pem file into one file:
$ cat PushCert.pem PushKey1_Rmv.pem > ApnsDev.pem
