15.2 Debug Mode
When Debug Mode is used, the analyzer will use the pre-defined Diffie Hellman private key and public keys that
are used with this mode to automatically decrypt the traffic.
15.3 Proper Entry of Link Key
Entry of a link key into the
Security
pane may be needed to decrypt traffic, especially for SSP pairings. This can
be done during a capture or after a capture is saved. Different methods for proper entry of a link key are
discussed below.
To enter a link key in hex (lowest order byte on left):
Specify each byte of the Link Key in hex, starting with the lowest order byte on the left. In this case DO NOT
use ":" as a separator and use either "0x" for every byte, or do not use it at all, as shown below:
0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08 0x09 0x0A 0x0B 0x0C 0x0D 0x0E 0x0F 0x10
01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10
01020304:05060708:090A0B0C:0D0E0F10
To enter a link key in hex (highest order byte on left):
Specify the Link Key as a big hex number, with highest order byte on the left. Use ":" as a separator
and/or
specify a single "0x" at the beginning, as shown below:
0x100F0E0D:0C0B0A09:08070605:04030201
100F0E0D:0C0B0A09:08070605:04030201
0x100F0E0D0C0B0A090807060504030201
15.4 Synchronization to Overviews
Each displayed security event is linked to the pertinent Overview by a timestamp column, includes an indication
of the applicable master/slave connection, shows the calculated (or provided) link key, the PIN code (as
applicable), and the authenticated ciphering offset (ACO).
To synchronize the Overview to a security event:
Left click on the timestamp associated with any security event shown in the
Security
pane.
The Overview jumps to the location of the selected timestamp.
