Embodiment 1

[0039] The present embodiment provides a method for obfuscating java code, which is applied to obfuscate the compiled jar package and the java code in the compilation process, and the method includes the following steps:

[0040] Step 1. Obtain the file to be obfuscated.

[0041] In this embodiment, the file to be confused is a jar package or java code in the compilation stage.

[0042] Step 2, judging the type of the file to be obfuscated, obfuscating the file to be obfuscated, and generating an obfuscated jar package.

[0043] figure 1 It is a flowchart of jar package obfuscation and encryption in the java code obfuscation method according to an embodiment of the present invention. Such as figure 1 As shown, when the file to be obfuscated is a jar package, the jar package obfuscation encryption method includes:

[0044]S201, parsing the jar package, and locating the location of the classes folder;

[0045] S202. Read the configuration, obtain obfuscation rules, and dete...

Embodiment 2

[0058] Such as image 3 As shown, a kind of java code obfuscation system is provided in the present embodiment, the java code obfuscation system adopts the aforementioned java code obfuscation method to obfuscate the jar package after code compilation and the java code in the compiling process; the java code obfuscation The system includes a configuration module 11 , an obfuscation scheme selection module 12 , an obfuscation module 13 and a verification module 14 .

[0059] In this embodiment, the configuration module 11 is configured to read a configuration file, which includes configured character pair classes, methods, and fields. The obfuscation scheme selection module 12 is used to select obfuscated characters, determine non-obfuscated files and obtain obfuscation rules according to the read configuration file.

Abstract

The invention relates to the technical field of computers, in particular to a java code obfuscation method and system, computer equipment and a storage medium. The method comprises the steps of obtaining a to-be-confused file, judging the type of the to-be-confused file, when the to-be-confused file is a jar package, analyzing the jar package, positioning the position of a classes folder, reading a configuration file, performing confusion replacement, and generating a new jar package; and when the to-be-obfuscated file is a java code in a compiling stage, adding obfuscation tool dependency in the java code, starting an obfuscation tool for obfuscation during compiling, generating a file downloading address of an obfuscated jar packet import or export result, and downloading an import or export result file according to the downloading address. The obfuscation scheme and the obfuscation range can be selected in a user-defined mode, the character string encryption function is achieved, the function logic of the obfuscated code is not affected, the code reading difficulty is greatly improved, the code safety is achieved, and a user has high configurability.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a java code obfuscation method, system, computer equipment and storage medium. Background technique [0002] Java is a C++ type object-based programming language. It has a wide range of usability and is currently a more popular programming language because the Java platform can be installed on a large number of different applicable devices and is widely used for web, app and server development. [0003] In the application of java code, if the compiled jar package is directly placed on the server, once the server is hacked or the file is leaked during the uploading of the jar package, criminals can easily obtain the source code through reverse engineering and guess the code Logic, so as to find system loopholes and carry out attacks, so it is the consensus of the industry to protect the source code. However, there is no effective java code protection method at present. Conte...
