The btkey
program is used to manage
Bluetooth Link Key storage. Keys are normally handled by the
bthcid(8) daemon which caches
them in the /var/db/bthcid.keys file and provides
them as required when Bluetooth connections need to be authenticated.
These keys are required for connections between remote devices and
the specific controller (not the Operating System) and so for multi-boot
systems where it may not always be possible to specify the same key across
all OS's it can be better to have the Bluetooth controller provide the keys
directly from its semi-permanent memory once devices are paired.
btkey
will read, write or clear keys in device
memory or the key cache as required.
Note that without the bthcid(8) daemon running users will be unable to supply PINs, and Link Keys resulting from new pairings will not be stored. If no new pairings are expected and the keys are stored in the controller then bthcid(8) is not required.
The options are as follows:
-a
address-C
-c
-d
device-k
key-L
-l
-R
-r
-W
-w
Super-user privileges are required to read or write link keys.
The btkey
utility exits 0 on
success, and >0 if an error occurs.
