Abstract
A certification or signature is incorporated in a computer program, an executable file, or code to assure its authenticity and integrity, particularly for receiving it over an open computer network like the Internet. The executable file may be of any executable form, including an executable or portable executable .exe file format, a .cab cabinet file format, an .ocx object control format, or a Java class file. The certification includes a keyed source confirmation with a secure representation of the executable file. In an embodiment, the certification is referenced in a header of the executable file, the reference including a pointer to the keyed source confirmation and an indication of the size of the keyed source confirmation.
