A java-like encryption and decryption method and computer-readable storage medium

Abstract

The present application relates to a Java-like encryption and decryption method and a computer-readable storage medium, wherein the Java-like encryption method uses a key to encrypt the first bytecode-like file to obtain the ciphertext of the first bytecode-like file, Generate a second bytecode class file with the same name as the first bytecode class file, write the ciphertext of the first bytecode class file into the second bytecode class file, and the second bytecode class file has the same name as the first bytecode class file A bytecode file has the same scanning characteristics, so that the bytecode tool scans the second bytecode file as the first bytecode file. In the decryption method, during the loading process of the class loader, the loading process is intercepted, and the decryption process is started, and the ciphertext of the first bytecode class file is obtained from the second bytecode class file, and decrypted using the key to obtain the second bytecode class file. A bytecode class file. Through this application, an encryption and decryption process that is completely transparent to Java applications and Java frameworks is realized.

Description

technical field [0001] This application relates to the field of computer program source code encryption and decryption, in particular to a Java-like encryption and decryption method and a computer-readable storage medium. Background technique [0002] Obfuscated code, also known as obfuscated code, is the behavior of converting the code of a computer program into a functionally equivalent but difficult to read and understand form. Code obfuscation can be used for program source code, or for intermediate code compiled from the program. Programs that perform code obfuscation are called code obfuscators. In related technologies, there are already many code obfuscators with different functions. [0003] Code obfuscation only sets the difficulty of human reading and understanding, and can still be decompiled into human-readable source code through decompilation tools, and many applications use the Spring framework or other Dependency Injection (DI for short) IOC (Inversion of C...

AI Technical Summary

Problems solved by technology

[0007] The encryption and decryption process implemented by this scheme is relatively safe, but this scheme causes many popular Java frameworks (such as Spring Framework, Hibernate, Apache Tomcat) to fail to scan these encrypted Classes during the startup phase, resulting in the failure of Java applications to start normally.
