Package Exports
- javascript-obfuscator
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (javascript-obfuscator) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
JavaScript obfuscator for Node.js
JavaScript obfuscator for Node.js is a free alternative of js-obfuscator (which uses javascriptobfuscator.com) without any limits and sending data to a server. Compatible with ES6. Tested on Angular2 bundle. https://gist.github.com/sanex3339/ffc2876123b52e6d11ce45369fd53acf
Installation
Install the package with NPM and add it to your devDependencies:
npm install --save-dev javascript-obfuscator
Usage
var JavaScriptObfuscator = require('javascript-obfuscator');
var obfuscatedCode = JavaScriptObfuscator.obfuscate(
`
(function(){
var variable = 'abc';
console.log(variable);
})();
`,
{
rotateUnicodeArray: false
}
);
console.log(obfuscatedCode);
/*
var _0xabf1 = [
'\x61\x62\x63',
'\x6c\x6f\x67'
];
(function() {
var _0xe6fab6 = _0xabf1[0x0];
console[_0xabf1[0x1]](_0xe6fab6);
}());
*/obfuscate(sourceCode, options)
sourceCode
Type: string Default: null
Any valid SourceCode.
options
Type: Object Default: null
Options for JavaScript obfuscator:
{
rotateUnicodeArray: true
// ...
}Available options
compact
Type: boolean Default: true
Compact code output into one line.
debugProtection
Type: boolean Default: false
⚠️ This option can cause browser freeze while Developer Tools is enabled! Use at own risk.
Force enable debug mode in some browsers (mainly based on WebKit) on page load if Developer Tools panel is enabled. With this options using of Debug panel is impossible.
WebKit-based browsers: blocks the site window, but you still can navigate through Developer Tools panel. Firefox: does not block the site window, but you still can't use Debug panel.
debugProtectionInterval
Type: boolean Default: false
⚠️ This option can cause browser freeze even while Developer Tools is disabled! Use at own risk.
Works if debugProtection is enabled.
Force enable debug mode in some browsers (mainly based on WebKit) when Developer Tools panel was enabled, even after page was loaded.
disableConsoleOutput
Type: boolean Default: true
Disable console.log, console.info, console.error and console.warn messages output into browser console.
encodeUnicodeLiterals
Type: boolean Default: false
⚠️ unicodeArray option must be enabled
This option can slightly slowdown your code speed.
All literals in unicode array becomes encoded in Base64.
To decode strings, special function will be inserted on page under unicodeArray node.
reservedNames
Type: string[] Default: []
Disable obfuscation of variable names, function names and names of function parameters that match with given RegExp pattern.
Example:
{
reservedNames: [
'^someVariable',
'functionParameter_\d'
]
}rotateUnicodeArray
Type: boolean Default: true
⚠️ unicodeArray option must be enabled
This option will rotate all values inside unicodeArray on a random value during obfuscation of code, and insert inside source code helper function
which will rotate array values back to their original indexes.
Keep in mind that this option affects only how the code is visually organised, since the original arrays can be easily accessed during the debug process.
It is also not recommended to enable rotateUnicodeArray for small source code, because a helper function might attract attention.
selfDefending
Type: boolean Default: true
⚠️ this option forces set the compact value to true
Enables self-defending for obfuscated code. If obfuscated compact code will be formatted, this code will not work.
unicodeArray
Type: boolean Default: true
Put all literal strings into array and replace every literal string by array call.
unicodeArrayThreshold
Type: number Default: 0.8 Min: 0 Max: 1
⚠️ unicodeArray option must be enabled
Probability that the literal string will inserted into unicodeArray.
Use this option for huge source code size, because many calls to unicodeArray will slowdown code performance.
Value 0 is equals unicodeArray: false.
wrapUnicodeArrayCalls
Type: boolean Default: true
⚠️ unicodeArray option must be enabled
Instead using direct calls to unicodeArray items var t = _0x43a123[0x0],
when index 0x0 can be easily reverted to 0 with few js beautifiers, this option will wrap all calls to special function instead.
var t = _0x12a634('0x0')License
