The following steps are necessary in order to prepare Apple's push certificate for deployment on Strategy Intelligence Server 9.4.x-10.x. It is assumed a push certificate has already been downloaded and added to the Keychain Access assistant on OSX.
1. Export certificate and private key from Keychain Access.
a. Select login on the left hand menu. Expand the downloaded certificate as seen on the screenshot below:
b. Export certificate and private key separately. First, export the certificate by right-clicking it and choosing "Export".
c. Select a name (e.g. apns-cert.p12) and choose .p12 as format.
d. When prompted for a password, leave it blank. When prompted for a system password, provide your OSX user password.
e. Perform steps b-d for the private key. Select a name (e.g. apns-key.p12)
2. Converting .p12 Certificate and .p12 Private Key files into a single .pem file. Execute the following commands in Terminal after navigating to the folder containing both, the certificate .p12 and key .p12 files:
a. Convert certificate .p12 file into .pem file
openssl pkcs12 -clcerts -nokeys -out apns-cert.pem -in apns-cert.p12
openssl pkcs12 -nocerts -out apns-key.pem -in apns-key.p12
openssl rsa -in apns-key.pem -out apns-key-noenc.pem
cat apns-cert.pem apns-key-noenc.pem > apns-prod.pem
