Abstract: A method, system, and computer program product for dynamically adjusting an encryption level based on the geographic location of a software program is disclosed. The geographic location associated with the software program is determined 202, for example, through use of a Global Positioning System (GPS) of a computer system (fig. 1) on which the software is running. A suitable encryption level is then selected 204 and the software program executed 210. In one embodiment, the selected encryption level may be overridden by a smart card (122, fig. 1) or other secure device connected to the computer system. The encryption levels may include a US encryption level, non-French European encryption level and a French encryption level. The invention allows a single piece of software to conform to various encryption regulations.
