Role-enforcement Using Hardware Keys
The Toolkit application is used to prepare important and confidential license
policies. Hence, it is important to restrict the unauthorized access to the
Toolkit. To control this, you are provided with a developer key, a hardware

tasks (such as, prototyping the protection strategies, etc.). You can
further prevent unauthorized use of your developer key by setting a password
for it. This will ensure that any malicious user having access to your
developer key cannot use it to tamper the protection strategy or program the
Sentinel Keys, Also, once you have programmed Sentinel Keys for your customers,
