generate pem file
# 1. Convert the .cer file into a .pem file:
$ openssl x509 -in aps_development.cer -inform der -out PushChatCert.pem
# 2. Convert the private key’s .p12 file into a .pem file:
$ openssl pkcs12 -nocerts -in PushChatKey.p12 -out PushChatKey.pem
# 3. Finally, combine the certificate and key into a single .pem file
$ cat PushChatCert.pem PushChatKey.pem > ck.pem
# 4. At this point it’s a good idea to test whether the certificate works.
$ telnet gateway.sandbox.push.apple.com 2195
# 5. Let’s try connecting again, this time using our SSL certificate and private key to set up a secure connection.
$ openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert PushChatCert.pem -key PushChatKey.pem
