Abstract
Methods, systems and computer program products are provide for controlling access to software is provided by the software to be controlled being divided into a first encrypted portion and a second unencrypted portion. The second unencrypted portion has access to, and may even incorporate, a first secret value and a software identification associated with a copy of the software. The first encrypted portion is encrypted with a first key value which is based on the first secret value and a second secret value. The second secret value is obtained and the first key value generated from the obtained second secret value and the first secret value. The first encrypted portion of the software may then be decrypted with the first key value. The software may be installed on a data processing system utilizing the decrypted first encrypted portion of the software.
