⚠️ Important  ⚠️ 重要

Only obfuscate the code that belongs to you.
只混淆属于你的代码。

It is not recommended to obfuscate vendor scripts and polyfills, since the obfuscated code is 15-80% slower (depends on options) and the files are significantly larger.
不建议对供应商脚本和 polyfill 进行模糊处理,因为经过模糊处理的代码速度慢 15-80%(取决于选项),并且文件明显更大。

obfuscate(sourceCode, options)

Returns ObfuscationResult object which contains two public methods:
返回 ObfuscationResult 包含两个公共方法的对象:

  • getObfuscatedCode() – returns string with obfuscated code;
    getObfuscatedCode() – 返回 string 带有混淆代码;
  • getSourceMap() – if sourceMap option is enabled – returns string with source map or an empty string if sourceMapMode option is set as inline;
    getSourceMap() – 如果选项已启用 – string 如果 sourceMapMode sourceMap 选项设置为 inline ;
  • getIdentifierNamesCache() – returns object with identifier names cache if identifierNamesCache option is enabled, null overwise.
    getIdentifierNamesCache() – 如果启用选项,则返回带有标识符名称缓存的对象, identifierNamesCache null 过度。

Calling toString() for ObfuscationResult object will return string with obfuscated code.
调用 toString() ObfuscationResult 对象将返回 string 模糊代码。

Method takes two parameters, sourceCode and options – the source code and the options respectively:
方法有两个参数, sourceCode 并且 options – 分别是源代码和选项:

  • sourceCode (string, default: null) – any valid source code, passed as a string;
    sourceCode ( , 默认值: null ) – 任何有效的源代码 string ,作为字符串传递;
  • options (Object, default: null) – an object with options.
    options ( Object , 默认值: null ) – 带有选项的对象。

For available options, see options.
有关可用选项,请参阅选项。

obfuscateMultiple(sourceCodesObject, options)

Accepts sourceCodesObject that is a map which keys are identifiers of source codes and values are source codes:
接受 sourceCodesObject 这是一个映射,其中键是源代码的标识符,值是源代码:

{
    foo: 'var foo = 1;',
    bar: 'var bar = 2;'
}

Returns a map object which keys are identifiers of source codes and values are ObfuscationResult objects.
返回一个 map 对象,其键是源代码的标识符,值是 ObfuscationResult 对象。

getOptionsByPreset(optionsPreset)

Returns an options object for the passed options preset name.
返回传递的选项预设名称的选项对象。

CLI usage 命令行界面用法

See CLI options. 请参阅 CLI 选项。

Obfuscate single file 对单个文件进行模糊处理

Usage: 用法:

javascript-obfuscator input_file_name.js [options]
javascript-obfuscator input_file_name.js --output output_file_name.js [options]
javascript-obfuscator input_file_name.js --output output_folder_name [options]
javascript-obfuscator input_folder_name --output output_folder_name [options]

Obfuscation of single input file with .js extension.
对带有扩展名的 .js 单个输入文件进行混淆。

If the destination path is not specified with the --output option, the obfuscated file will be saved into the input file directory, with INPUT_FILE_NAME-obfuscated.js name.
如果未使用该 --output 选项指定目标路径,则经过模糊处理的文件将保存到输入文件目录中,并 INPUT_FILE_NAME-obfuscated.js 带有名称。

Some examples: 一些例子:

javascript-obfuscator samples/sample.js --compact true --self-defending false
// creates a new file samples/sample-obfuscated.js

javascript-obfuscator samples/sample.js --output output/output.js --compact true --self-defending false
// creates a new file output/output.js

Obfuscate directory recursively
递归混淆目录

Usage: 用法:

javascript-obfuscator ./dist [options]
// creates a new obfuscated files under `./dist` directory near the input files with `obfuscated` postfix

javascript-obfuscator ./dist --output ./dist/obfuscated [options]
// creates a folder structure with obfuscated files under `./dist/obfuscated` path

Obfuscation of all .js files under input directory. If this directory contains already obfuscated files with -obfuscated postfix – these files will ignored.
对输入目录下的所有 .js 文件进行模糊处理。如果此目录包含已混淆的带有后缀的文件 -obfuscated – 这些文件将被忽略。

Obfuscated files will saved into the input directory under INPUT_FILE_NAME-obfuscated.js name.
经过模糊处理的文件将保存到名称下的 INPUT_FILE_NAME-obfuscated.js 输入目录中。

Conditional comments 条件注释

You can disable and enable obfuscation for specific parts of the code by adding following comments:
您可以通过添加以下注释来禁用和启用代码特定部分的模糊处理:

  • disable: // javascript-obfuscator:disable or /* javascript-obfuscator:disable */;
    禁用: // javascript-obfuscator:disable 或 /* javascript-obfuscator:disable */ ;
  • enable: // javascript-obfuscator:enable or /* javascript-obfuscator:enable */.
    启用: // javascript-obfuscator:enable 或 /* javascript-obfuscator:enable */ 。

Example: 例:

// input
var foo = 1;
// javascript-obfuscator:disable
var bar = 2;

// output
var _0xabc123 = 0x1;
var bar = 2;

Conditional comments affect only direct transformations of AST-tree nodes. All child transformations still will be applied to the AST-tree nodes.
条件注释仅影响 AST 树节点的直接转换。所有子转换仍将应用于 AST 树节点。

For example: 例如:

  • Obfuscation of the variable’s name at its declaration is called direct transformation;
    在声明变量名称时对变量名称进行模糊处理称为直接转换;
  • Obfuscation of the variable’s name beyond its declaration is called child transformation.
    在声明之外对变量名称进行模糊处理称为子转换。

Kind of variables 变量的种类

Kind of variables of inserted nodes will auto-detected, based on most prevailing kind of variables of source code.
插入节点的变量类型将根据源代码中最常见的变量类型自动检测。

Conflicts of identifier names between different files
不同文件之间的标识符名称冲突

During obfuscation of the different files, the same names can be generated for the global identifiers between these files. To prevent this set the unique prefix for all global identifiers for each obfuscated file with identifiersPrefix option.
在对不同文件进行模糊处理期间,可以为这些文件之间的全局标识符生成相同的名称。要防止这种情况,请使用选项为每个 identifiersPrefix 模糊处理文件的所有全局标识符设置唯一前缀。

When using CLI this prefix will be added automatically.
使用 CLI 时,将自动添加此前缀。

类型:默认: string[] []

⚠️ This option does not work with target: 'node'
⚠️ 此选项不适用于 target: 'node'

Allows to run the obfuscated source code only on specific domains and/or sub-domains. This makes really hard for someone to just copy and paste your source code and run it elsewhere.
允许仅在特定域和/或子域上运行经过混淆的源代码。这使得某人很难复制和粘贴您的源代码并在其他地方运行它。

If the source code isn’t run on the domains specified by this option, the browser will be redirected to a passed to the domainLockRedirectUrl option URL.
如果源代码未在此选项指定的域上运行,则浏览器将被重定向到传递 domainLockRedirectUrl 到选项 URL。

Multiple domains and sub-domains
多个域和子域

It’s possible to lock your code to more than one domain or sub-domain. For instance, to lock it so the code only runs on http://www.example.com add www.example.com. To make it work on the root domain including any sub-domains (example.comsub.example.com), use .example.com.
可以将代码锁定到多个域或子域。例如,要锁定它,以便代码仅在 http://www.example.com 添加 www.example.com .要使其在根域(包括任何子域 (, example.com , sub.example.com )上工作,请使用 .example.com 。

启用字符串文本的强制转换,这些文本与传递的 RegExp 模式匹配。

⚠️ This option affects only strings that shouldn’t be transformed by stringArrayThreshold (or possible other thresholds in the future)
⚠️ 此选项仅影响不应被 stringArrayThreshold 转换的字符串(或将来可能的其他阈值)

The option has a priority over reservedStrings option but hasn’t a priority over conditional comments.
该选项的优先级高于选项,但优先级不高于 reservedStrings conditional comments 。

Example: 例:

   {
        forceTransformStrings: [
            'some-important-value',
            'some-string_\d'
        ]
    }

identifierNamesCache

Type: Object | null Default: null
类型:默认: Object | null null

The main goal for this option is the ability to use the same identifier names during obfuscation of multiple sources/files.
此选项的主要目标是能够在混淆多个源/文件期间使用相同的标识符名称。

Currently the two types of the identifiers are supported:
目前支持两种类型的标识符:

  • Global identifiers:  全局标识符:
    • All global identifiers will be written to the cache;
      所有全局标识符都将写入缓存;
    • All matched undeclared global identifiers will be replaced by the values from the cache.
      所有匹配的未声明全局标识符都将替换为缓存中的值。
  • Property identifiers, only when renameProperties option is enabled:
    属性标识符,仅当启用选项时 renameProperties :

    • All property identifiers will be written to the cache;
      所有属性标识符都将写入缓存;
    • All matched property identifiers will be replaced by the values from the cache.
      所有匹配的属性标识符都将替换为缓存中的值。

Node.js API 节点.js API

If a null value is passed, completely disables the cache.
如果传递了 null 值,则完全禁用缓存。

If an empty object ({}) is passed, enables the writing identifier names to the cache-object (TIdentifierNamesCache type). This cache-object will be accessed through the getIdentifierNamesCache method call of ObfuscationResult object.
如果传递了空对象 ( {} ),则启用将标识符名称写入缓存对象( TIdentifierNamesCache 类型)。此缓存对象将通过对象的方法 ObfuscationResult 调用进行 getIdentifierNamesCache 访问。

The resulting cache-object can be next used as identifierNamesGenerator option value for using these names during obfuscation of all matched identifier names of next sources.
生成的缓存对象接下来可以用作选项值, identifierNamesGenerator 以便在对下一个源的所有匹配标识符名称进行模糊处理期间使用这些名称。

Example: 例:

const source1ObfuscationResult = JavaScriptObfuscator.obfuscate(
    `
        function foo(arg) {
           console.log(arg)
        }
        
        function bar() {
            var bark = 2;
        }
    `,
    {
        compact: false,
        identifierNamesCache: {},
        renameGlobals: true
    }
)

console.log(source1ObfuscationResult.getIdentifierNamesCache());
/*
    { 
        globalIdentifiers: {
            foo: '_0x5de86d',
            bar: '_0x2a943b'
        }
    }
*/



const source2ObfuscationResult = JavaScriptObfuscator.obfuscate(
    `
        // Expecting that these global functions are defined in another obfuscated file
        foo(1);
        bar();
        
        // Expecting that this global function is defined in third-party package
        baz();
    `,
    {
        compact: false,
        identifierNamesCache: source1ObfuscationResult.getIdentifierNamesCache(),
        renameGlobals: true
    }
)

console.log(source2ObfuscationResult.getObfuscatedCode());
/*
    _0x5de86d(0x1);
    _0x2a943b();
    baz();
 */

CLI 命令行界面

CLI has a different option --identifier-names-cache-path that allows defining a path to the existing .json file that will be used to read and write identifier names cache.
CLI 有一个不同的选项 --identifier-names-cache-path ,允许定义将用于读取和写入标识符名称缓存的现有 .json 文件的路径。

If a path to the empty file will be passed – identifier names cache will be written to that file.
如果将传递空文件的路径 – 标识符名称缓存将写入该文件。

This file with existing cache can be used again as --identifier-names-cache-path option value for using these names during obfuscation of all matched identifier names of the next files.
具有现有缓存的此文件可以再次用作选项值, --identifier-names-cache-path 以便在对下一个文件的所有匹配标识符名称进行模糊处理期间使用这些名称。

  • safe – default behaviour after 2.11.0 release. Trying to rename properties in a more safe way to prevent runtime errors. With this mode some properties will be excluded from renaming.
    safe – 发布后 2.11.0 的默认行为。尝试以更安全的方式重命名属性以防止运行时错误。使用此模式,某些属性将从重命名中排除。
  • unsafe – default behaviour before 2.11.0 release. Renames properties in an unsafe way without any restrictions.
    unsafe – 发布前 2.11.0 的默认行为。以不安全的方式重命名属性,没有任何限制。

If one file is using properties from other file, use identifierNamesCache option to keep the same property names between these files.
如果一个文件使用另一个文件中的属性,请使用选项在 identifierNamesCache 这些文件之间保留相同的属性名称。

reservedNames

Type: string[] Default: []
类型:默认: string[] []

Disables obfuscation and generation of identifiers, which being matched by passed RegExp patterns.
禁用模糊处理和标识符的生成,这些标识符与传递的 RegExp 模式匹配。

Example: 例:

   {
        reservedNames: [
            '^someVariable',
            'functionParameter_\d'
        ]
    }

reservedStrings

This option sets seed for random generator. This is useful for creating repeatable results.
此选项为随机生成器设置种子。这对于创建可重复的结果很有用。

If seed is 0 – random generator will work without seed.
如果种子是 0 – 随机生成器将在没有种子的情况下工作。

selfDefending

Type: boolean Default: false
类型:默认: boolean false

⚠️ Don’t change obfuscated code in any way after obfuscation with this option, because any change like uglifying of code can trigger self defending and code wont work anymore!
⚠️ 使用此选项进行混淆后,不要以任何方式更改混淆代码,因为任何更改(如代码丑化)都可能触发自我防御,并且代码将不再有效!
⚠️ This option forcibly sets compact value to true

⚠️ in future releases obfuscation of boolean literals (true => !![]) will be moved under this option.
⚠️ 在将来的版本中,文本的 boolean 模糊处理 ( true => !![] ) 将移至此选项下。

Example: 例:

// input
if (condition1) {
    const foo = 1;
    const bar = 2;
  
    console.log(foo);
  
    return bar;
} else if (condition2) {
    console.log(1);
    console.log(2);
    console.log(3);
  
    return 4;
} else {
    return 5;
}

// output
if (condition1) {
    const foo = 0x1, bar = 0x2;
    return console['log'](foo), bar;
} else
    return condition2 ? (console['log'](0x1), console['log'](0x2), console['log'](0x3), 0x4) : 0x5;

sourceMap

Type: boolean Default: false
类型:默认: boolean false

Enables source map generation for obfuscated code.
为模糊代码启用源映射生成。

Source maps can be useful to help you debug your obfuscated JavaScript source code. If you want or need to debug in production, you can upload the separate source map file to a secret location and then point your browser there.
源映射可用于帮助您调试经过混淆的 JavaScript 源代码。如果要或需要在生产环境中进行调试,可以将单独的源映射文件上传到机密位置,然后将浏览器指向该位置。

sourceMapBaseUrl

Type: string Default: “
类型: string 默认:“”

Sets base url to the source map import url when sourceMapMode: 'separate'.
在 时 sourceMapMode: 'separate' 将基本网址设置为源映射导入网址。

CLI example: 命令行示例:

javascript-obfuscator input.js --output out.js --source-map true --source-map-base-url 'http://localhost:9000'

Result: 结果:

//# sourceMappingURL=http://localhost:9000/out.js.map

sourceMapFileName

Type: string Default: “
类型: string 默认:“”

Sets file name for output source map when sourceMapMode: 'separate'.
在以下情况下 sourceMapMode: 'separate' 设置输出源映射的文件名。

CLI example: 命令行示例:

javascript-obfuscator input.js --output out.js --source-map true --source-map-base-url 'http://localhost:9000' --source-map-file-name example

Result: 结果:

//# sourceMappingURL=http://localhost:9000/example.js.map

sourceMapMode

Type: string Default: separate
类型:默认: string separate

Specifies source map generation mode:
指定源映射生成模式:

  • inline – add source map at the end of each .js files;
    inline – 在每个.js文件的末尾添加源映射;
  • separate – generates corresponding ‘.map’ file with source map. In case you run obfuscator through CLI – adds link to source map file to the end of file with obfuscated code //# sourceMappingUrl=file.js.map.
    separate – 生成带有源映射的相应“.map”文件。如果您通过 CLI 运行混淆器 – 将指向源映射文件的链接添加到带有混淆代码 //# sourceMappingUrl=file.js.map 的文件末尾。

sourceMapSourcesMode

Type: string Default: sources-content
类型:默认: string sources-content

Allows to control sources and sourcesContent fields of the source map:

    sources-content – 添加虚拟字段,添加 sourcesContent 带有原始源代码的 sources 字段;
  • sources – adds sources field with a valid source description, does not add sourcesContent field. When using NodeJS API it’s required to define inputFileName option that will be used as sources field value.
    sources – 添加具有有效源描述的字段,不添加 sources sourcesContent 字段。使用 NodeJS API 时,需要定义 inputFileName 将用作字段值的选项 sources 。

splitStrings

Type: boolean Default: false
类型:默认: boolean false

Splits literal strings into chunks with length of splitStringsChunkLength option value.
将文本字符串拆分为具有 splitStringsChunkLength 选项值长度的块。

Example: 例:

// input
(function(){
    var test = 'abcdefg';
})();

// output
(function(){
    var _0x5a21 = 'ab' + 'cd' + 'ef' + 'g';
})();

splitStringsChunkLength

Type: number Default: 10
类型:默认: number 10

Sets chunk length of splitStrings option.
设置选项的 splitStrings 区块长度。

stringArray

Type: boolean Default: true
类型:默认: boolean true

删除字符串文本并将它们放在特殊数组中。例如,中的 var m = "Hello World"; 字符串 "Hello World" 将被替换为类似 var m = _0x12c456[0x1];

stringArrayCallsTransform

Type: boolean Default: false
类型:默认: boolean false

⚠️ stringArray option must be enabled
⚠️ stringArray 必须启用选项

        r: '0x399'
    };
    var c = i(k.d, k.e);
    var d = i(k.f, k.g);
    var e = i(k.h, k.l);
    var f = i(k.m, k.n);
    function i(c, d) {
        return b(c - k.c, d);
    }
    var g = i(k.o, k.p);
    var h = i(k.q, k.r);
}
function j(c, d) {
    var l = { c: 0x14b };
    return b(c - -l.c, d);
}
console[j(-'0xa6', -'0xa6')](foo());
function b(c, d) {
    var e = a();
    b = function (f, g) {
        f = f - 0xa3;
        var h = e[f];
        return h;
    };
    return b(c, d);
}
function a() {
    var m = [
        'string5',
        'string1',
        'log',
        'string3',
        'string6',
        'string2',
        'string4'

        return m;
    };
    return a();
}

stringArrayEncoding

Type: string[] Default: []
类型:默认: string[] []

⚠️ stringArray option must be enabled
⚠️ stringArray 必须启用选项

This option can slow down your script.
此选项可能会减慢脚本速度。

Encode all string literals of the stringArray using base64 or rc4 and inserts a special code that used to decode it back at runtime.
对 stringArray using base64 or rc4 的所有字符串文本进行编码,并插入用于在运行时将其解码的特殊代码。

Each stringArray value will be encoded by the randomly picked encoding from the passed list. This makes possible to use multiple encodings.
每个 stringArray 值将由从传递的列表中随机选择的编码进行编码。这使得使用多个编码成为可能。

Available values: 可用值:

  • 'none' (boolean): doesn’t encode stringArray value
    'none' ( boolean ): 不对值进行编码 stringArray
  • 'base64' (string): encodes stringArray value using base64
    'base64' ( ): string 使用 对 base64 值进行编码 stringArray
  • 'rc4' (string): encodes stringArray value using rc4About 30-50% slower than base64, but more harder to get initial values. It’s recommended to disable unicodeEscapeSequence option when using rc4 encoding to prevent very large size of obfuscated code.
    'rc4' ( string ): 使用 对 rc4 值进行编码 stringArray 。比 慢 base64 大约 30-50%,但更难获得初始值。建议在使用 rc4 编码时禁用 unicodeEscapeSequence 选项,以防止非常大的模糊代码。

For example with the following option values some stringArray value won’t be encoded, and some values will be encoded with base64 and rc4 encoding:
例如,使用以下选项值,某些值不会被编码,而某些 stringArray 值将使用和 rc4 编码进行 base64 编码:

stringArrayEncoding: [
    'none',
    'base64',
    'rc4'
]

⚠️ stringArray 必须启用选项

Allows to control the type of string array call indexes.
允许控制字符串数组调用索引的类型。

Each stringArray call index will be transformed by the randomly picked type from the passed list. This makes possible to use multiple types.
每个 stringArray 调用索引将由传递的列表中随机选择的类型进行转换。这使得可以使用多种类型。

Available values: 可用值:

  • 'hexadecimal-number' (default): transforms string array call indexes as hexadecimal numbers
    'hexadecimal-number' ( default ): 将字符串数组调用索引转换为十六进制数
  • 'hexadecimal-numeric-string': transforms string array call indexes as hexadecimal numeric string
    'hexadecimal-numeric-string' :将字符串数组调用索引转换为十六进制数字字符串

Before 2.9.0 release javascript-obfuscator transformed all string array call indexes with hexadecimal-numeric-string type. This makes some manual deobfuscation slightly harder but it allows easy detection of these calls by automatic deobfuscators.
在发布 javascript-obfuscator 之前 2.9.0 ,使用类型转换 hexadecimal-numeric-string 了所有字符串数组调用索引。这使得一些手动去混淆稍微困难一些,但它允许自动去混淆器轻松检测这些调用。

The new hexadecimal-number type approaches to make harder auto-detect of string array call patterns in the code.
