ReencryptSecureInformation Method (WMI MSReportServer_ConfigurationSetting)
Generates a new encryption key and re-encrypts all secure information in the catalog using this new key.
The ReencryptSecureInformation method allows the administrator to replace the existing encryption key with a new key.
When this method is invoked, the report server generates a new encryption key and iterates through all encrypted content to re-encrypt it with the new encryption key.
Delivery extensions can store secured information in their delivery settings structures. When ReencryptSecureInformation is called, the report server loads each subscription and the corresponding delivery extension to re-encrypt information stored in the associated settings.
If this method is run on a computer in a scale-out deployment, each computer in the scale-out deployment will need to be initialized again.
