A method for generating key information for mutual access among multiple computers, the method including configuring each of a plurality of computers to access common seed data, where the common seed data is the same for each of the computers, and configuring each of the computers to intercept a key generator request for computer-specific seed data and, in response to the request, provide the common seed data to the key generator in place of the computer-specific seed data, thereby enabling any of the computers to generate the same key information.
