1. A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform method steps of a software provider (25) enabling a software-acquiring entity (20) to arrive from an existent first signed piece of code (11), which is executable on a machine, at a second signed piece of code (12, 13), which is executable on the machine, both pieces of code (11, 12, 13) having been generated by use of a first software archive generator (2) under use of generation instructions (8), comprising the step of:

  • providing to said software-acquiring entity (20) a difference code (4, 5), said difference code comprising the steps necessary to arrive from said first signed piece of code (11) at said second signed piece of code (12, 13), said steps further including instructions to amend said first signed piece of code so that a signature belonging to said second signed piece of code is the same signature for a corresponding second signed piece of code existing at the software provider, said difference code (4, 5) is usable at said software-acquiring entity (20); and

    amending using said difference code said first signed piece of code (11) by a second software archive generator (7) to generate said second signed piece of code (12, 13), whereby said second software archive generator (7) is fed with those generation instructions (8) that were used by said first software archive generator (2) for the generation of both pieces of code (11, 12, 13).
