edit:

the certificate used created certificate , private key follows:

openssl pkcs12 -clcerts -nokeys -out apns-dev-cert.pem -in apns-dev-cert.p12 openssl pkcs12 -nocerts -out apns-dev-key.pem -in apns-dev-key.p12 cat apns-dev-cert.pem apns-dev-key.pem > apns-dev.pem 

here how working:

from within keychain export following both in p12 format, without giving password:

• apple development push services certificate cert.p12
• primary key under apple development push services pkey.p12

in terminal go directory have exported certificates , convert p12 files pem format , concatenate them follows:

$ openssl pkcs12 -in pkey.p12 -out pkey.pem -nodes -clcerts $ openssl pkcs12 -in cert.p12 -out cert.pem -nodes -clcerts $ cat cert.pem pkey.pem > iphone_ck.pem 

iphone_ck.pem certificate need.
