Making a PEM File for iOS Push Notifications (From Ray Wenderlich's tutorial)
# Convert the .cer file into a .pem file:
$ openssl x509 -in aps_development.cer -inform der -out PushChatCert.pem
# Convert the private key’s .p12 file into a .pem file:
$ openssl pkcs12 -nocerts -in PushChatKey.p12 -out PushChatKey.pem
# Finally, combine the certificate and key into a single .pem file
$ cat PushChatCert.pem PushChatKey.pem > ck.pem
# At this point it’s a good idea to test whether the certificate works.
