APNS Certificate

Development:

Step 1: Create Certificate .pem from Certificate .p12

openssl pkcs12 -clcerts -nokeys -out apns-dev-cert.pem -in apns-dev-cert.p12

Step 2: Create Key .pem from Key .p12

openssl pkcs12 -nocerts -out apns-dev-key.pem -in apns-dev-key.p12

Step 3: Optional (If you want to remove pass phrase asked in second step)

openssl rsa -in apns-dev-key.pem -out apns-dev-key-noenc.pem

Step 4: Now we have to merge the Key .pem and Certificate .pem to get Development .pem needed for Push Notifications in Development Phase of App

If 3rd step is performed: cat apns-dev-cert.pem apns-dev-key-noenc.pem > apns-dev.pem

If 3rd step is not performed: cat apns-dev-cert.pem apns-dev-key.pem > apns-dev.pem

Step 5: Check certificate validity and connectivity to APNS

If 3rd step is not performed : openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert apns-dev-cert.pem -key apns-dev-key.pem

If 3rd step is not performed: openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert apns-dev-cert.pem -key apns-dev-key-noenc.pem

Production:

Step 1: Create Certificate .pem from Certificate .p12

openssl pkcs12 -clcerts -nokeys -out apns-pro-cert.pem -in apns-pro-cert.p12

Step 2: Create Key .pem from Key .p12

openssl pkcs12 -nocerts -out apns-pro-key.pem -in apns-pro-key.p12

Step 3: Optional (If you want to remove pass phrase asked in second step)

openssl rsa -in apns-pro-key.pem -out apns-pro-key-noenc.pem

Step 4: Now we have to merge the Key .pem and Certificate .pem to get Production .pem needed for Push Notifications in Production Phase of App

If 3rd step is performed: cat apns-pro-cert.pem apns-pro-key-noenc.pem > apns-pro.pem

If 3rd step is not performed: cat apns-pro-cert.pem apns-pro-key.pem > apns-pro.pem

Step 5: Check certificate validity and connectivity to APNS

If 3rd step is not performed : openssl s_client -connect gateway.push.apple.com:2195 -cert apns-pro-cert.pem -key apns-pro-key.pem

If 3rd step is not performed: openssl s_client -connect gateway.push.apple.com:2195 -cert apns-pro-cert.pem -key apns-pro-key-noenc.pem
