Key Data is a 64-byte space in the Key that allows you to store data for any purposes such as configurations, username, password, etc. Besides, in advanced operation, you can also use Key Data to store custom licensing properties that are not available under Key Limits. For example, you may store upgradable data or values such as credits for your application. With support for string addition, you can also provide license upgrades through Key Data.
