iOS Generate PEM Push certificate

1. Login to IPhone Developer Connection Portal (http://developer.apple.com/iphone/manage/overview/index.action) and click on App IDs

2. Create an App ID that does not use a wildcard character. Wildcard IDs cannot be used with push Notification Services. For example, Com.itotem.iphone

3. Click "Configure" next to the app ID and press the button to produce the push notification license. Follow the steps in the wizard to generate a signature and upload it, and finally download the generated license.

4. Introduce your aps_developer_identity.cer into the keychain by double-clicking the. cer file.

5. Start the Keychain assistant on your Mac, and then select the Certificates category in the login keychain. You will see an extensible option "Apple Development Push Services"

6. Expand this option and right-click Apple Development Push Services > Export Apple Development Push services ID123. Save As Apns-dev-cert.p12 file .

7. Extend "Apple development Push Services" to "Private Key" and save as APNS-DEV-KEY.P12 file.

8. These files need to be converted to PEM format via terminal commands : OpenSSL pkcs12-clcerts-nokeys-out apns-dev-cert.pem-in APNS-DEV-CERT.P12

OpenSSL pkcs12-nocerts-out apns-dev-key.pem-in APNS-DEV-KEY.P12

9. If you want to remove the password, either do not set or execute it when exporting/converting:

OpenSSL rsa-in apns-dev-key.pem-out Apns-dev-key-noenc.pem

10. Finally, you need to synthesize the key and license file into a APNS-DEV.PEM file, which you need to use when connecting to APNs:

Cat Apns-dev-cert.pem Apns-dev-key-noenc.pem > Apns-dev.pem
