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
