Authenticode - sign a DOS

Need to be able to sign a WINDOWS ".EXE" with an authenticode cert directly on a unix box. Preferable solution to be done in JAVA, but willing to accept anything that can make this happen on a unix box. .EXE code is a windows PKZIP Stub that gets data attached to it once its placed in the unix enviroment. during the Unix attachment, I need to be able to brand the stream with a valid cert. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform IBM AIX, UNIX WIN2k, XP IE only solution
