Abstract

The invention discloses a merged execution method for PE file codes, which belongs to a file encryption technique and solves the problem that a single file code is easy to be illegally utilized in the prior art. The merged execution method for the PE file codes comprises: (1) establishing a PE file header; (2) establishing section information; (3) merging various PE file data to a corresponding section and forming a novel PE file; (4) processing mutual calling relations between various PE files; (5) attaching codes of initialized data of the various PE files to the novel PE file; and (6) adding an attached processing code for the merged PE file according to actual demands, and expanding corresponding functions. The method not only realizes the merging of various PE file codes but also can realize dynamic or static encryption of the merged PE file or addition of additional functional codes, effectively protect the various file codes, and prevent the single file code from being illegally utilized.

Description

technical field

[0001] The invention relates to a file merging method, in particular to a PE file code merging execution method capable of realizing encryption protection after PE file merging. Background technique

[0002] The operation and mutual calling of traditional PE files exist in the discontinuous linear memory space of a process. Every time a new PE file is loaded, Windows opens up a new piece of memory from the memory space of the process according to the relevant information of the PE file. , and then load the data of the PE file into this memory block, and then process the import table of the PE file and other related data that needs to be initialized. Not fixed, every time a newly loaded PE file is initialized, it is necessary to recalculate and correct the calling code between PEs. In general, each PE file is a separate file.

[0003] The codes between traditional PE files call each other such as figure 1 As shown, assuming that there are two PE files, A.EX...
