The Key Manager library, *SYSTEM/KMAPI/SUPPORT, handles the creation of database encryption keys for the Enterprise Database Server. When a database that contains encrypted items is compiled, the database software calls the MCAPISUPPORT library which in turn calls the Key Manager library to create a database encryption key set. The Key Manager library is also called when a database containing encrypted items is opened.

The Key Manager library uses the Security Center database. The Key Manager library must be upgraded at the same time that the Security Center server is upgraded. Refer to Introduction to Security Center for more details about the Security Center database.
