Step 8 - creating mdm.p12

[EeOneDown]

Hi

Is there are ways to create mdm.p12 with out Keychain Access?

I know that the first part of the step (getting User ID) can be done using Openssl:

openssl x509 -noout -subject -in <file_from_apns>.pem

But what about mdm.p12? Or even PushCert.pem?

Thanks
