Attributes
Attribute Description Default Setting
Write-Random If selected, a unique random string will
be written as the feature value when
the Sentinel Key is programmed. You
can specify its length in the String
Length field.
The random value is generated by the
Sentinel Key itself and is not known to
you/your application. However, you
can call the SFNTReadString API
function to read the value.
Please note that this value can be
overwritten in the field using the
Update value command or by calling
the SFNTWriteString API function
(requires the write password
you specified).
Read-Only Select this check box if you do not
want to allow writing the feature
value by the protected application
(that calls the SFNTWriteString API
function).
