Remote Update Codes
Request Code
Refers to the code generated (as a .req file) by the customers/distributors as a
request to update their hardware keys. It contains the hardware key details
(such as, the serial number) and the license information.
Update Code
Refers to the code generated by the developer. It defines the actions that you
want to apply on the hardware key. The update code is generated under the
Key Activator tab of the Toolkit.
As a developer, only you have the rights for generating update codes to allow
secure remote update.
Note: An update code can also be generated using the SFNTCreateUpdatePacket
API function of the Key Programming library.
The update packets created using this function can be applied as a buffer
and saved as a *.upw file to be further applied into the end user token
using either the Secure Update Utility, or the SFNTApplyUpdateCode
function from the Secure Update library.
