I just lost my private key with OS reinstallation so will have to create new Certificate Signing Requests.. I wanted to know if revoking my Distribution Certificate<
Often developers face this question and stay away from revoking a certificate. Possible thoughts are if it affect the app in the store, or will the same certificate be required for the next update etc.
But there are no any issues like that. An Appstore and Adhoc production certificates are used for the App store submission process only. It needs to check the private key public key pair to validate that the ipa is code signed by a valid signing authority. Once the app goes to app store you need not have to bother about the certificate used.
The next time for creating an update, you can codesign using a different certificate, but you need to use the same app id.
