Yes. To do this you include the user name or company name in the Product Info or Authentication Data when you generate the license key. You can then extract this information when the license is checked and display it prominently in your software window and printouts to discourage customers from sharing keys.
If you are using Authenticated Licenses then using AuthenticationData is prefererable because it doesn't affect the length of the license key. Using a long Product Info string will result in a longer license key. So an alternative approach for simple encrypted licensing is to only include a checksum of the user/company name. You then add a registration screen to your software that allows the user to enter their details. When the license is checked you extract the Product Info and ensure it matches the checksum of the entered details.
License Tracker includes support for customizing the key generation process (through the use of a Custom Generator). This allows you to automatically generate the ProductInfo or AuthenticationData from customer or sales data. It also allows you to prompt the user for other information that you wish to include in the license key. _________________ Infralution Support |
