开发那点事(十三)您的小程序代码被盗用,如何保证代码安全

2020-08-11  本文已影响0人  极客简讯

写在前面的话
小编前段时间刷博客的时候看到了一篇这样的文章,大概的内容是开发者辛辛苦苦开发小半年的作品,上线没几天,就被人盗版上线了,甚至连代码都是扒的自己的,有兴趣的朋友可以去看看。点我查看

至于说怎么去扒微信小程序的源码,小编在这里不做过多的阐述,自行百度“小程序代码反编译”

今天咱们来讲讲如何在提交审核之前,给自己的小程序代码做混淆,代码安全加固。

核心思路

首先咱们来介绍一下javascript-obfuscator

在百度上对它的定义是这样的“javascript-obfuscator是一个免费的JavaScript代码混淆工具,它功能强大,可以把你的源代码变得“面目全非”,完全没有可读性。还具有部分防调试功能,给JavaScript代码多一层保护。”

事实上也确实是这样,小编通过它来对项目进行混淆之后,代码的可读性变得极其差。

const a0_0x1cf1 = ['getStorageSync', 'scope.userInfo', 'getSystemInfo', 'now', 'userInfo', 'unshift', 'getSystemInfo:ok', 'log', 'getSetting', 'logs', 'setStorageSync', 'systemInfo', 'userInfoReadyCallback', 'authSetting', 'errMsg'];
(function (_0x371ccf, _0x1cf103) {
  const _0x5d052b = function (_0x13fa3f) {
    while (--_0x13fa3f) {
      _0x371ccf['push'](_0x371ccf['shift']());
    }
  };
  _0x5d052b(++_0x1cf103);
}(a0_0x1cf1, 0x14b));
const a0_0x5d05 = function (_0x371ccf, _0x1cf103) {
  _0x371ccf = _0x371ccf - 0x0;
  let _0x5d052b = a0_0x1cf1[_0x371ccf];
  return _0x5d052b;
};
App({
  'onLaunch': function () {
    let _0x2e1d11 = this;
    var _0x451dd8 = wx[a0_0x5d05('0xe')]('logs') || [];
    _0x451dd8[a0_0x5d05('0x4')](Date[a0_0x5d05('0x2')]()), wx[a0_0x5d05('0x9')](a0_0x5d05('0x8'), _0x451dd8), wx[a0_0x5d05('0x1')]({
      'complete': _0x1f36a4 => {
        console[a0_0x5d05('0x6')](_0x1f36a4, a0_0x5d05('0x1')), (_0x1f36a4[a0_0x5d05('0xd')] = a0_0x5d05('0x5')) && (_0x2e1d11[a0_0x5d05('0xa')] = _0x1f36a4);
      }
    }), wx[a0_0x5d05('0x7')]({
      'success': _0x3eebf4 => {
        _0x3eebf4[a0_0x5d05('0xc')][a0_0x5d05('0x0')] && wx['getUserInfo']({
          'success': _0x306423 => {
            this['globalData'][a0_0x5d05('0x3')] = _0x306423[a0_0x5d05('0x3')], this[a0_0x5d05('0xb')] && this['userInfoReadyCallback'](_0x306423);
          }
        });
      }
    });
  },
  'globalData': {
    'userInfo': null
  },
  'systemInfo': {}
});

话不多说,上干货

javascript-obfuscator的安装

npm init -f
npm install formidable --save
npm install -g javascript-obfuscator
npm install --save-dev javascript-obfuscator

javascript-obfuscator的用法

javascript-obfuscator input.js --output output.js
--target 'browser-no-eval'
--disable-console-output true
--debug-protection true
--debug-protection-interval true
--identifier-names-generator 'hexadecimal'
--string-array true
--rotate-string-array true
--string-array-encoding 'rc4'
--string-array-threshold 0.8
javascript-obfuscator a.js --config test.json --output b.js

官方推荐的三种配置

{
    compact: true,
    controlFlowFlattening: true,
    controlFlowFlatteningThreshold: 1,
    deadCodeInjection: true,
    deadCodeInjectionThreshold: 1,
    debugProtection: true,
    debugProtectionInterval: true,
    disableConsoleOutput: true,
    identifierNamesGenerator: 'hexadecimal',
    log: false,
    renameGlobals: false,
    rotateStringArray: true,
    selfDefending: true,
    stringArray: true,
    stringArrayEncoding: 'rc4',
    stringArrayThreshold: 1,
    transformObjectKeys: true,
    unicodeEscapeSequence: false
}
{
    compact: true,
    controlFlowFlattening: true,
    controlFlowFlatteningThreshold: 0.75,
    deadCodeInjection: true,
    deadCodeInjectionThreshold: 0.4,
    debugProtection: false,
    debugProtectionInterval: false,
    disableConsoleOutput: true,
    identifierNamesGenerator: 'hexadecimal',
    log: false,
    renameGlobals: false,
    rotateStringArray: true,
    selfDefending: true,
    stringArray: true,
    stringArrayEncoding: 'base64',
    stringArrayThreshold: 0.75,
    transformObjectKeys: true,
    unicodeEscapeSequence: false
}
{
    compact: true,
    controlFlowFlattening: false,
    deadCodeInjection: false,
    debugProtection: false,
    debugProtectionInterval: false,
    disableConsoleOutput: true,
    identifierNamesGenerator: 'hexadecimal',
    log: false,
    renameGlobals: false,
    rotateStringArray: true,
    selfDefending: true,
    stringArray: true,
    stringArrayEncoding: false,
    stringArrayThreshold: 0.75,
    unicodeEscapeSequence: false
}

当然以上所说,都只是针对单个js文件的处理方法,要想针对整个项目中的js文件,则还需要借助bat脚本来实现
