Application obfuscation method and device, server and storage medium

Abstract

The embodiment of the invention provides an application obfuscation method and device, a server and a storage medium. The method includes: replacing a first class name of a code file in an applicationwith a character string, wherein the character strings used for replacing the same first class name are the same, and character strings for replacing different first class names are different; secondly, searching response, replacing a first class name of a code file in the application with class name mapping information generated by the character string, and determining a target character stringused for replacing a second class name in a resource file of the application, wherein the class name mapping information comprises each first class name in the code file and a character string used for replacing the first class name; and finally, replacing the second class name in the application with the first class name replaced with the target character string to obtain the target application.According to the technical scheme provided by the invention, not only is the cracking cost of the application increased, but also the difficulty of reversely cracking the application is increased, sothat the labor fruits of technicians are protected, and the occurrence of loopholes is avoided.

Description

technical field [0001] The present invention relates to the technical field of mobile application security, and more specifically, relates to an application obfuscation method, device, server and storage medium. Background technique [0002] With the continuous development of society, Android applications are becoming more and more popular. People's requirements for Android application security are also getting higher and higher. Therefore, in the process of packaging the corresponding Android application, it is necessary to obfuscate the code in the Android application, that is, use meaningless characters to replace the method name, class name and field in the code, so as to increase the difficulty of understanding the code. [0003] Using meaningless characters to replace method names, class names, and fields in the code can increase the difficulty of understanding the code, but the attacker can still see the original information in the application after decompiling the A...
