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.
