Abstract

The invention provides an executable file encryption method and apparatus. The encryption method comprises the steps of obtaining address information of symbols in a partition table of an executable file in an application installation package, wherein the symbols are used for storing content information of the executable file; according to the obtained address information of the symbols, determining to-be-encrypted symbols in the executable file of the application installation package; based on a predetermined encryption algorithm, encrypting the to-be-encrypted symbols; and replacing the to-be-encrypted symbols in the application installation package with the encrypted symbols corresponding to the address information of the corresponding symbols, thereby generating an encrypted executable file. Through the method and the apparatus, the to-be-encrypted symbols in the executable file of the application installation package can be quickly encrypted simply and conveniently without additional development cost, so that the difficulty of performing decompilation and analysis on the executable file is increased.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular, the present invention relates to an executable file encryption method and an executable file encryption device. Background technique [0002] With the rapid development of software-related technologies, people's life and work are more dependent on applications, and their security awareness is gradually increasing. On the one hand, after the application is released, it is easy to be decompiled and expose its source code, resulting in the theft of the relevant core technology of the application, causing huge economic losses to the developer. The risk of the code threatens the security of the user's personal privacy; on the other hand, as a special product, the application program has been plagued by piracy since its inception due to its digital characteristics. Developers have caused huge losses and have greatly hindered the development of the entire software industry. Us...
