.Os
.Sh NAME
.Nm btkey
.Nd Bluetooth Link Key management utility
.Sh SYNOPSIS
.Nm
.Op Fl cCrRwW
.Op Fl k Ar key
.Fl a Ar address
.Fl d Ar device
.Nm
.Fl lL
.Op Fl d Ar device
.Sh DESCRIPTION
The
.Nm
program is used to manage Bluetooth Link Key storage.
Keys are normally handled by the
.Xr bthcid 8
daemon which caches them in the
.Pa /var/db/bthcid.keys
file and provides them as required when Bluetooth connections
need to be authenticated.
.Pp
These keys are required for connections between remote
devices and the specific controller
.Pq 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.
.Nm
will read, write or clear keys in device memory or the key cache
as required.
.Pp
Note that without the
.Xr 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
.Xr bthcid 8
is not required.
.Pp
The options are as follows:
.Bl -tag -width ".Fl a Ar address"
.It Fl a Ar address
Specify the remote device address.
May be given as a BDADDR or a name.
.It Fl c
Clear key from file.
.It Fl C
Clear key from device.
.It Fl d Ar device
Specify the local device address.
May be given as a BDADDR or a name.
.It Fl k Ar key
Supply a Link Key as a string of hexadecimal digits.
Up to 32 digits will be processed and the resulting key
will be zero padded to 16 octets.
.It Fl l
List keys stored in file.
.It Fl L
List keys stored in device.
.It Fl r
Read key from file.
.It Fl R
Read key from device.
.It Fl w
Write key to file.
.It Fl W
Write key to device.
.El
.Pp
Super-user privileges are required to read or write link keys.
.Sh EXAMPLES
.Pp
Read key for mouse at ubt0 from file and write to device
.Pp
.Dl btkey -d ubt0 -a mouse -rW
.Pp
Write new key for keyboard at ubt0 to file
.Pp
.Dl btkey -d ubt0 -a keyboard -k 92beda6cd8b8f66ebd2af270d55d70ec -w
.Pp
Clear key for phone at bt3c0 from file and device
.Pp
.Dl btkey -d bt3c0 -a phone -cC
.Pp

The

Some of the functionality of

Keys may be examined, deleted or moved to device storage using the
.Xr btkey 1
program.

The only way to make the

daemon forget a link key is to edit the

file by hand.
.Pp
The only way to specify link keys (useful when multiple operating
systems are used on the same hardware), is to edit the
