Key Identifier: %1
A key that is used by the Data Protection application programming interface (DPAPI) is being recovered. Because the DPAPI keys are backed up on Active Directory, the computer can automatically recover a key when necessary. This message is logged for informational purposes only. It usually follows a Security 596 message, which indicates that the DPAPI key was backed up. There may be a period of days or weeks between the messages.
