Abstract
Techniques for providing access rights to different portions of a software application to one or more authorized users are described herein. An issuance license may be inserted into the software application that divides the software application into one or more portions and identifies, for each portion, one or more users that are authorized access to the portion. Each portion of the software application may then be encrypted using, for example, a different cryptographic key. When the software is executed, an end user license may then be requested that corresponds to a particular user and that entitles the particular user access to each portion of the software application that the issuance license identifies the particular user as being authorized to access. The end user license may then be used to decrypt each portion of the software application that the issuance license identifies the particular end user as being authorized to access.
