Development Phase:
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 was performed, run:
cat apns-dev-cert.pem apns-dev-key-noenc.pem > apns-dev.pem
If 3rd step was not performed, run:
cat apns-dev-cert.pem apns-dev-key.pem > apns-dev.pem
Step 5: Check certificate validity and connectivity to APNS
If 3rd step was performed, run:
openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert apns-dev-cert.pem -key apns-dev-key-noenc.pem
If 3rd step was not performed, run:
openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert apns-dev-cert.pem -key apns-dev-key.pem
Production Phase:
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 was performed, run:
cat apns-pro-cert.pem apns-pro-key-noenc.pem > apns-pro.pem
If 3rd step was not performed, run:
cat apns-pro-cert.pem apns-pro-key.pem > apns-pro.pem
Step 5: Check certificate validity and connectivity to APNS.
If 3rd step was performed, run:
openssl s_client -connect gateway.push.apple.com:2195 -cert apns-pro-cert.pem -key apns-pro-key-noenc.pem
If 3rd step was not performed, run:
openssl s_client -connect gateway.push.apple.com:2195 -cert apns-pro-cert.pem -key apns-pro-key.pem
How do I create a .pem file to be stored in the hosting server for APN payload data?
