As per apple, we can now take advantage of a simpler method of authentication by using tokens instead of certificates when sending push notifications. Here
As per documentation, for generating Push Package we need a Signature file which is PKCS #7 detached signature of the manifest file. This signature file is generated using the Private Key associated with the web push certificate obtained while registering with Apple.
I am not able to figure out how to generate Signature file from the authentication token, instead of web push certificate file.
