Which API features will you use?
62 Sentinel Hardware Keys Developer’s Guide
There are seven API features provided in the Toolkit, including AES and
ECC. In general, you must include at least one AES feature to implement the
query-response protection (see page 172). Other factors that help you in
choosing appropriate features are:
Estimate the number of independent features that need to be
controlled/licensed.
Decide your licensing policy, such as whether you want to provide
perpetual licenses or demo or try-and-buy licenses. You can create
time-limited or executions-limited demos. These can be combined
with a suitable remote activation method to provide try-and-buy
licenses.
Identify the data that needs to be digitally signed/ verified and
encrypted/decrypted. Depending on which you will add one or more
AES and ECC features.
Identify the critical data that need to be protected, such as the user
registration number. Using data type features (String, Boolean, Raw
Data, and Integers), you can store variety of data in the Sentinel Key
memory.
Note: While creating the license groups you can modify the licensing settings,
such as the expiration date, time, or execution count. This will NOT affect
the CodeCover or API implemented in the application/source code.
