vite下javascript-obfuscator 代码混淆

文章vite下javascript-obfuscator 代码混淆分享给大家，欢迎收藏Java资料网，专注分享技术知识

1.Vite混淆处理

项目环境：Vue3+Vite

1、安装

yarn add --dev rollup-plugin-obfuscator javascript-obfuscator

或者

npm install --save-dev rollup-plugin-obfuscator javascript-obfuscator

在打包时候还会报错，需要安装下面的依赖

yarn add javascript-obfuscator -D

2、引入

在vite.config.ts中引入插件，并进行设置

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import obfuscator from 'rollup-plugin-obfuscator';
export default defineConfig({
  // base: "",
  build: {
    minify: 'esbuild', // 默认
  },
  esbuild: {
    drop: ['console', 'debugger'],//打包去除
  },
  plugins: [
    vue(),
    obfuscator({
      global:false,
      // options配置项实际为 javascript-obfuscator 选项，具体可查看https://github.com/javascript-obfuscator/javascript-obfuscator
      options: {
        compact: true,
	      controlFlowFlattening: true,
	      deadCodeInjection: true,
	      debugProtection: true,
	      debugProtectionInterval: 0,
	      disableConsoleOutput: false,
	      identifierNamesGenerator: "hexadecimal",
	      log: false,
	      numbersToExpressions: false,
	      renameGlobals: false,
	      selfDefending: false,
	      simplify: true,
	      splitStrings: false,
	      stringArray: true,
	      stringArrayCallsTransform: false,
	      stringArrayCallsTransformThreshold: 0.5,
	      stringArrayEncoding: [],
	      stringArrayIndexShift: true,
	      stringArrayRotate: true,
	      stringArrayShuffle: true,
	      stringArrayWrappersCount: 1,
	      stringArrayWrappersChainedCalls: true,
	      stringArrayWrappersParametersMaxCount: 2,
	      stringArrayWrappersType: "variable",
	      stringArrayThreshold: 0.75,
	      unicodeEscapeSequence: false,
      }
    })
  ]
})

3、配置项解释

关于 rollup-plugin-obfuscator 插件的配置选项列表，每个选项都用于定制代码混淆和压缩的方式。可以参看javascript-obfuscator 的配置表

4.官方推荐的几种配置

1.高混淆，低性能。性能会比没有混淆的时候慢很多

{
    compact: true,
    controlFlowFlattening: true,
    controlFlowFlatteningThreshold: 1,
    deadCodeInjection: true,
    deadCodeInjectionThreshold: 1,
    debugProtection: true,
    debugProtectionInterval: 4000,
    disableConsoleOutput: true,
    identifierNamesGenerator: 'hexadecimal',
    log: false,
    numbersToExpressions: true,
    renameGlobals: false,
    selfDefending: true,
    simplify: true,
    splitStrings: true,
    splitStringsChunkLength: 5,
    stringArray: true,
    stringArrayCallsTransform: true,
    stringArrayEncoding: ['rc4'],
    stringArrayIndexShift: true,
    stringArrayRotate: true,
    stringArrayShuffle: true,
    stringArrayWrappersCount: 5,
    stringArrayWrappersChainedCalls: true,    
    stringArrayWrappersParametersMaxCount: 5,
    stringArrayWrappersType: 'function',
    stringArrayThreshold: 1,
    transformObjectKeys: true,
    unicodeEscapeSequence: false
}

2.中等混淆，最佳性能。性能会比没有混淆时慢

{
    compact: true,
    controlFlowFlattening: true,
    controlFlowFlatteningThreshold: 0.75,
    deadCodeInjection: true,
    deadCodeInjectionThreshold: 0.4,
    debugProtection: false,
    debugProtectionInterval: 0,
    disableConsoleOutput: true,
    identifierNamesGenerator: 'hexadecimal',
    log: false,
    numbersToExpressions: true,
    renameGlobals: false,
    selfDefending: true,
    simplify: true,
    splitStrings: true,
    splitStringsChunkLength: 10,
    stringArray: true,
    stringArrayCallsTransform: true,
    stringArrayCallsTransformThreshold: 0.75,
    stringArrayEncoding: ['base64'],
    stringArrayIndexShift: true,
    stringArrayRotate: true,
    stringArrayShuffle: true,
    stringArrayWrappersCount: 2,
    stringArrayWrappersChainedCalls: true,
    stringArrayWrappersParametersMaxCount: 4,
    stringArrayWrappersType: 'function',
    stringArrayThreshold: 0.75,
    transformObjectKeys: true,
    unicodeEscapeSequence: false
}

3.低混淆、高性能。表现会处于比较正常的水平

{
    compact: true,
    controlFlowFlattening: false,
    deadCodeInjection: false,
    debugProtection: false,
    debugProtectionInterval: 0,
    disableConsoleOutput: true,
    identifierNamesGenerator: 'hexadecimal',
    log: false,
    numbersToExpressions: false,
    renameGlobals: false,
    selfDefending: true,
    simplify: true,
    splitStrings: false,
    stringArray: true,
    stringArrayCallsTransform: false,
    stringArrayEncoding: [],
    stringArrayIndexShift: true,
    stringArrayRotate: true,
    stringArrayShuffle: true,
    stringArrayWrappersCount: 1,
    stringArrayWrappersChainedCalls: true,
    stringArrayWrappersParametersMaxCount: 2,
    stringArrayWrappersType: 'variable',
    stringArrayThreshold: 0.75,
    unicodeEscapeSequence: false
}

4.默认预设，高性能

{
    compact: true,
    controlFlowFlattening: false,
    deadCodeInjection: false,
    debugProtection: false,
    debugProtectionInterval: 0,
    disableConsoleOutput: false,
    identifierNamesGenerator: 'hexadecimal',
    log: false,
    numbersToExpressions: false,
    renameGlobals: false,
    selfDefending: false,
    simplify: true,
    splitStrings: false,
    stringArray: true,
    stringArrayCallsTransform: false,
    stringArrayCallsTransformThreshold: 0.5,
    stringArrayEncoding: [],
    stringArrayIndexShift: true,
    stringArrayRotate: true,
    stringArrayShuffle: true,
    stringArrayWrappersCount: 1,
    stringArrayWrappersChainedCalls: true,
    stringArrayWrappersParametersMaxCount: 2,
    stringArrayWrappersType: 'variable',
    stringArrayThreshold: 0.75,
    unicodeEscapeSequence: false
}
