Answer 2

According to Troubleshooting Push Certificate Problems

The SSL certificate available in your Apple Developer Program account contains a public key but not a private key. The private key exists only on the Mac that created the Certificate Signing Request uploaded to Apple. Both the public and private keys are necessary to export the Privacy Enhanced Mail (PEM) file.

Chances are the reason you can't export a working PEM from the certificate provided by the client is that you do not have the private key. The certificate contains the public key, while the private key probably only exists on the Mac that created the original CSR.

You can either:

1. Try to get the private key from the Mac that originally created the CSR. Exporting the PEM can be done from that Mac or you can copy the private key to another Mac.

or

2. Create a new CSR, new SSL certificate, and this time back up the private key.

Answer 3

There's much simpler solution today — pem. This tool makes life much easier.

For example, to generate or renew your push notification certificate just enter:

fastlane pem 

and it's done in under a minute. In case you need a sandbox certificate, enter:

fastlane pem --development

And that's pretty it.

To enable Push Notification for your iOS app, you will need to create and upload the Apple Push Notification Certificate (.pem file) to us so we will be able to connect to Apple Push Server on your behalf.

(Updated version with updated screen shots Here)

Step 1: Login to iOS Provisioning Portal, click "Certificates" on the left navigation bar. Then, click "+" button.

Step 2: Select Apple Push Notification service SSL (Production) option under Distribution section, then click "Continue" button.

Step 3: Select the App ID you want to use for your BYO app (How to Create An App ID), then click "Continue" to go to next step.

Step 4: Follow the steps "About Creating a Certificate Signing Request (CSR)" to create a Certificate Signing Request.

To supplement the instruction provided by Apple. Here are some of the additional screenshots to assist you to complete the required steps:

Step 4 Supplementary Screenshot 1: Navigate to Certificate Assistant of Keychain Access on your Mac.

Step 4 Supplementary Screenshot 2: Fill in the Certificate Information. Click Continue.

Step 5: Upload the ".certSigningRequest" file which is generated in Step 4, then click "Generate" button.

Step 6: Click "Done" to finish the registration, the iOS Provisioning Portal Page will be refreshed that looks like the following screen:

Then Click "Download" button to download the certificate (.cer file) you've created just now. - Double click the downloaded file to install the certificate into Keychain Access on your Mac.

Step 7: On your Mac, go to "Keychain", look for the certificate you have just installed. If unsure which certificate is the correct one, it should start with "Apple Production IOS Push Services:" followed by your app's bundle ID.

Step 8: Expand the certificate, you should see the private key with either your name or your company name. Select both items by using the "Select" key on your keyboard, right click (or cmd-click if you use a single button mouse), choose "Export 2 items", like Below:

Then save the p12 file with name "pushcert.p12" to your Desktop - now you will be prompted to enter a password to protect it, you can either click Enter to skip the password or enter a password you desire.

Step 9: Now the most difficult part - open "Terminal" on your Mac, and run the following commands:

cd
cd Desktop
openssl pkcs12 -in pushcert.p12 -out pushcert.pem -nodes -clcerts

Step 10: Remove pushcert.p12 from Desktop to avoid mis-uploading it to Build Your Own area. Open "Terminal" on your Mac, and run the following commands:

cd
cd Desktop
rm pushcert.p12

Step 11 - NEW AWS UPDATE: Create new pushcert.p12 to submit to AWS SNS. Double click on the new pushcert.pem, then export the one highlighed on the green only.

Now you have successfully created an Apple Push Notification Certificate (.p12 file)! You will need to upload this file to our Build Your Own area later on. :)
