Bytecode encryption method, bytecode decryption method and terminal

Abstract

The invention is applicable to the technical field of computers, and provides a byte code encryption method, a byte code decryption method and a terminal, and the method comprises the steps: configuring a path of a target Java packet to which a to-be-encrypted target byte code belongs in a POM (Project Object Model) based on a preset attribute when detecting that an encrypted plug-in packet existsin the POM; Obtaining a target Java packet, and packaging the target Java packet to generate a jar packet; Determining an encryption environment corresponding to the target byte code according to thepacket information of the jar packet; Calling a dynamic library through the Java class library, and setting a preset parameter corresponding to the encryption environment for the target byte code; And encrypting the set target byte code by adopting an encryption algorithm corresponding to the preset parameter to generate an encrypted jar package. According to the scheme, different encryption algorithms are adopted to encrypt the byte codes in different encryption environments, the byte codes are not prone to being cracked by agents, the byte code files are effectively protected, decompilationis prevented, and therefore source codes are effectively protected.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a bytecode encryption method, a bytecode decryption method and a terminal. Background technique [0002] The Java source code is compiled to generate a bytecode file (a file with a suffix of .class), and the generated bytecode file is interpreted and run in the Java virtual machine. [0003] Since the bytecode file is very self-describing and retains a lot of symbols and compilation information, the bytecode file is easily decompiled into a highly readable source code, resulting in the plagiarism of the developer's labor results or the product being destroyed. tamper. In the prior art, the bytecode file is usually encrypted by obfuscating variables or disrupting the code execution process, but such an encryption method is easy to be cracked by the agent, and cannot effectively protect the bytecode file and the source code. code. Contents of the invention [000...

AI Technical Summary

Problems solved by technology

[0004] In view of this, an embodiment of the present invention provides a bytecode encryption method, a bytecode decryption method, and a terminal to solve the problem of encrypting bytecodes by traditional encryption methods in existing technologies, resulting in The file is easy to be cracked, and the bytecode file cannot be effectively protected, so the source code cannot be effectively protected
