Apple APNs 2048-bit TLS/SSL certificate update
apple-push-notifications
Solution
Download the entrust_2048_ca.cer file, and install it on the servers that communicate with Apple's notification services. No need to do renew your actual push certificates, also you should not have to change anything in your code.
The important thing is that the servers that actually communicate with Apple's notification services have the certificate installed.
If you are lucky, your push server is already in contact with a Certificate Authority root, and this will solve the issue for you automagically. However, if you should lose that connection, your notifications will be out of order unless you have a "local" version of the certificate.
Problem
Today i received an email from apple telling they are changing something connected with push notifications, and wanted to ask what to do with the certificate they gave me link to... My server runs debian lenny, and im using php5 to send push notifications to apple apns. Do i have to just like... add it somewhere, or replace the 'old' one ?
