I am currently encountering an issue: when creating a new push certificate on the Apple Push Notification Certificates portal, I am required to generate a signature beforehand. Could you please explain the specific rules for this signature and how I should go about generating it? (I previously attempted to generate the certificate using the following command—openssl req -new -key mdm_push.key -out mdm_push.csr—but after uploading it, I received an error indicating an incorrect format.)

Not sure what may have gone wrong using the openssl command.
But you can also create a Certificate Signing Request using the Keychain Access app on your Mac.
Launch 'Keychain Access`, then select from the menu Keychain Access -> Certificate Assistant -> Request a certificate from a Certificate Authority
Then choose "Save to disk" and then you can use the CSR this created to request your push certificate.
