Android software package automatic encryption and decryption method, device and equipment and storage medium

Abstract

The embodiment of the invention provides an Android software package automatic encryption and decryption method, device and equipment and a storage medium, and the method comprises the steps: starting an encryption and decryption module which is pre-integrated in Android IDE packaging software when an instruction for packaging the Android software package is detected, wherein the encryption and decryption module comprises a gradle script for automatically encrypting a resource file and a code file, an automatic decryption entry function and an interception function for intercepting a Java layer system API (Application Program Interface); encrypting a plaintext resource file and a plaintext code file in the Android software package according to the gradle script, and inserting an automatic decryption entry function and an interception function for intercepting a Java layer system API (Application Program Interface) to obtain a plaintext resource file and a plaintext code file; and replacing the plaintext resource file and the plaintext code file with the ciphertext resource file and the plaintext code file to obtain an encrypted Android software package. According to the invention, the security and convenience of encryption and decryption of the installation software package can be improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a task management method, device, equipment and storage medium supporting automatic promotion. Background technique [0002] The software APK (Android application package) running on the Android operating system is an extended format based on the ZIP file format, and it is also a format file similar to the structure of the JAR file. A complete APK file must contain the compiled classes.dex code file, resources.arsc resource index file, assets native resource (not compressed and compiled) file, lib dynamic library so file, AndroidMainfest.xml manifest file, META-INF Package signature file, res binary resource file (except res / raw). Among them, there can be multiple classes.dex code files, and the naming rules are: classes.dex, classes2.dex, classes3.dex, and so on; resources.arsc is used to manage resource IDs and index files corresponding to resource paths; assets dire...

AI Technical Summary

Problems solved by technology

[0006] 1. Insufficient security

This solution only encrypts most resource files, and does not implement encryption protection for classes.dex code files and res / anim resource files, and there is still a risk of core function code and resource file leakage;

[0007] 2. Insufficient flexibility

[0008] Third, the practicality is not strong

In the decryption process of this scheme, the hook system API is required, including ApkAssets:Open, FindEntry at the java level, and FindEntry and FileDescriptor of libziparchive.so at the so level, which is not easy to implement in actual operation;

[0009] 4. Insufficient convenience

The operation steps are cumbersome and there are many details. Manual processing is not only time-consuming, but also error-prone
