All Options - JS-Confuser Docs

JS-Confuser provides a wide range of options to customize the obfuscation process. Below is a list of all available options in the obfuscator.

Remember, presets can be used to quickly apply a set of options to the obfuscator.

Build Settings

Option	Description
Target	The execution context for your output.
Pack	Packs the output code into a single `Function()` call. Designed to escape strict mode constraints.

Identifiers

Option	Description
Identifier Generator	Determines how variables are renamed.
Rename Variables	Determines if variables should be renamed.
Rename Globals	Renames top-level variables, turn this off for web-related scripts. Enabled by default.
Rename Labels	Renames labeled control-flow statements, and removes unnecessary labels. Enabled by default.
Moved Declarations	Moves variable declarations to the top of the context.

Strings

Option	Description
String Compression	String Compression uses zlib compression algorithm to compress strings.
String Concealing	String Concealing involves encoding strings to conceal plain-text values.
Custom String Encodings	Custom String Encodings allows you to define your own string encoding/decoding functions.
String Encoding	String Encoding transforms a string into an encoded representation.
String Splitting	String Splitting splits your strings into multiple expressions.

Data

Option	Description
Calculator	Creates a calculator function to handle arithmetic and logical expressions.
Object Extraction	Extracts object properties into separate variables.
Global Concealing	Global Concealing hides global variables being accessed.
Shuffle	Shuffles the initial order of arrays. The order is brought back to the original during runtime.
Duplicate Literals Removal	Duplicate Literals Removal replaces duplicate literals with a single variable name.

Control-flow

Option	Description
Control Flow Flattening	Control-flow Flattening hinders program comprehension by creating convoluted switch statements.
Dispatcher	Creates a middleman function to process function calls.
Opaque Predicates	An Opaque Predicate is a predicate(true/false) that is evaluated at runtime, this can confuse reverse engineers from understanding your code.
Dead Code	Randomly injects dead code.
AST Scrambler	Semantically changes the AST to bypass automated tools.

Functions

Option	Description
Variable Masking	Local variables are consolidated into a rotating array.
Flatten	Brings independent declarations to the highest scope.
RGF	RGF (Runtime-Generated-Functions) creates executable code from strings.

Lock

Option	Description
Domain Lock	Ensures the script can only execute on the specified domain. Set the Counter Measures option to control what happens if violated.
Start Date	When the program is first able to be used.
End Date	When the program is no longer able to be used.
Tamper Protection	Tamper Protection safeguards the runtime behavior from being altered by JavaScript pitfalls.
Self Defending	Prevents the use of code beautifiers or formatters against your code.
Custom Locks	Customize the lock algorithm to your own implementation.
Integrity	Integrity ensures the source code is unchanged.
Anti Debug	Adds debugger statements throughout the code.
Countermeasures	A custom callback function to invoke when a lock is triggered.

Output

Option	Description
Hexadecimal Numbers	Uses the hexadecimal representation for numbers.
Compact	Remove’s whitespace from the final output.
Minify	Minifies redundant code.
Preserve Function Length	Preserves the original `function.length` property.
