Abstract
A computer-implemented method and system for embedding ancillary information into the header of a digitally signed executable are disclosed. The method and system include identifying a digital signature block and a digital signature size block in a digitally signed file header, modifying a digital signature size value in the digital signature size block, the modified value corresponding to the size of the digital signature block plus the length of an ancillary data block plus a pre-determined pad, storing the modified digital signature size in the digital signature size block, and appending the ancillary data block to the end of the digital signature block.
