Encryption / Decryption Keys
A typical encryption or decryption key consists of a string of 32 characters, using any combination
of the numbers ‘
0 ’ through ‘ 9 ’ and the letters ‘ a ’ through ‘ f ’ / ‘ A ’ through ‘ F ’.
To program a key, enter the desired 32-character string in the appropriate key row, and then click
[Set] . Any previously programmed key may be overwritten in this manner. Alternately, click
[Clear] to reset a previously programmed entry to all zeroes, and then re-enter the new key string
as instructed here.
Up to eight keys may be programmed for each function; once set, you may then select a specified
Encryption Key for active use via the ‘ Configuration | Routing | Routes ’ page ( Sect.
7.5.4.3.3.1 ).
The user must program all eight encryption and decryption keys before selecting
Random Key operation on the ‘Configuration | Routing | Routes’ page. Otherwise,
the modem will select any of the eight allotted keys, even if a key is currently
clear (set to all zeroes).
