What happens when Apple revokes a certificate?

Question

Regarding the fact that in iOS distribution model, each App should be signed by a certificate issued by Apple (either developer license, enterprise license, appstore, etc.), I wonder what happens when this certificate gets voided (e.g. because of legal issues) by Apple?

• Does the signed app stop working as soon as the certificate is voided?
• Does the signed Apps stop working as soon as the user connects to internet?
• Does the signed Apps continue working, but cannot be updated?
• Does ... ???

Any Ideas?

Answer 1

The signed app remains signed and continues to work. But you will not be able to use the certificate to sign new apps.
