ABSTRACT:
A method of processing licensing keys includes specifying a program defining a set of executable instructions where different subsets of executable instructions define different products. A set of licensing keys are constructed. Each licensing key has a fixed number of symbols, where each symbol includes multiple bits. At least one symbol is configured to be mapped to at least two fields and at least one field is configured to be mapped to at least two symbols. Each field specifies a feature of a product defined by a subset of executable instructions of the program. The program and a first license key are distributed to a first end user, while the program and a second license key are distributed to a second end user. The first license key is processed to define features of a first product. The second license key is processed to define features of a second product.
