Abstract

An apparatus for encrypting a binary file is disclosed. The apparatus includes one or more processors and memory storing one or more programs to be executed by the one or more processors. The one or more programs include instructions for encrypting each segment from a set of segments of the binary file to define an encrypted binary file. The one or more programs also include instructions for packing the encrypted binary file and a shell program to produce a packed file. The one or more programs further include instructions for generating an executable file based on the packed file such that the shell program is executed to decrypt the encrypted binary file when the executable file is executed.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a file packing and unpacking method, device and system. Background technique [0002] Packing is a method of changing the encoding of executable program files or dynamic link library files through a series of mathematical operations to achieve the purpose of reducing file size or encrypting program encoding. [0003] In the prior art, there is no method for packing binary files running on the Android platform of the mobile terminal. Contents of the invention [0004] In view of this, the present invention provides a file packing and unpacking method, device and system, which can enhance the security of the Android system binary file and prevent it from being decompiled and decrypted by packing the Android system binary file. [0005] The file packing method that the embodiment of the present invention provides, comprises: [0006] Encrypt each piece of information of the bi...
