       KeyFile - Defines AFS server encryption keys


       The KeyFile file defines the server encryption keys that the AFS server
       processes running on the machine use to decrypt the tickets presented
       by clients during the mutual authentication process. AFS server
       processes perform privileged actions only for clients that possess a
       ticket encrypted with one of the keys from the file. The file must
       reside in the /etc/openafs/server directory on every server machine.
       For more detailed information on mutual authentication and server
       encryption keys, see the IBM AFS Administration Guide.

       Each key has a corresponding a key version number that distinguishes it
       from the other keys. The tickets that clients present are also marked
       with a key version number to tell the server process which key to use
       to decrypt it. The KeyFile file must always include a key with the same
       key version number and contents as the key currently listed for the
       "afs" entry in the Authentication Database.

       The KeyFile file is in binary format, so always use the appropriate
       commands from the bos command suite to administer it:

       ·   The bos addkey command to define a new key.

       ·   The bos listkeys command to display the keys.

       ·   The bos removekey command to remove a key from the file.

       In cells that use the Update Server to distribute the contents of the
       /etc/openafs/server directory, it is customary to edit only the copy of
       the file stored on the system control machine. Otherwise, edit the file
       on each server machine individually.
