Making Apple Apple Push Notification certificates on Linux

Making Apple Push Notification certificates on Linux

1. Create a new directory;
	mkdir Apple\ Enterprise
	cd Apple\ Enterprise

2. Generate a certificate signing request
	openssl req -nodes -newkey rsa:2048 -keyout aps.key -out CertificateSigningRequest.certSigningRequest

3. With the information like so (ensure you give it a password):
	Country Name (2 letter code) [AU]:GB
	State or Province Name (full name) [Some-State]:London
	Locality Name (eg, city) []:
	Organization Name (eg, company) [Internet Widgits Pty Ltd]:Total Onion Ltd
	Organizational Unit Name (eg, section) []:
	Common Name (e.g. server FQDN or YOUR name) []:Total Onion Enterprise
	Email Address []:

4. Login to developer.apple.com, go to:
	"Member Center" -> "Certificates, Identifiers & Profiles > Identifiers > Select App IDs, Scroll down select "Add/Edit" button Besides Push Notification

5. Go through the wizard, selecting the certificate type, and uploading the .csr.

6. Download the .cer file, saving it to the folder created in step 1

7. Convert the .cer file to a .pem file:
	openssl x509 -in aps.cer -inform DER -out aps.pem -outform PEM

8. Convert the .pem to a .p12:
	openssl pkcs12 -export -inkey aps.key -in aps.pem -out aps.p12

9. You can now use the aps certificate on OneSignal or any other similar platforms.

Wow, what a crazy process everything is with Apple. Thanks for posting this ... I'm just waiting for Apple to finish verifying my account, and then I'll be able to proceed to step 4.
