Jsfuck
jsfuck est un langage de programmation ésotérique et un obfuscateur de code source JavaScript. Il fonctionne comme un encodeur de code qui transforme le code source JavaScript standard en un équivalent fonctionnel composé d'un jeu de caractères minimal.
Le projet restreint son code source à six caractères spécifiques pour masquer la logique et contourner les filtres de sécurité qui bloquent les caractères alphanumériques standard. Il y parvient en utilisant la coercition de type pour dériver des symboles et accéder aux objets internes du langage via la manipulation de prototypes.
Le système permet l'exécution arbitraire de JavaScript en convertissant des chaînes en fonctions exécutables et en récupérant la portée globale via le contexte d'exécution. Il gère la logique complexe et les arguments de fonction en utilisant des wrappers de tableau et des appels de constructeur natifs.
Features
- Minimalist Character-Set Restrictions - Restricts the entire source code to only six specific characters to hide logic and bypass security filters.
- JavaScript Obfuscators - Transforms standard JavaScript source code into an obfuscated functional equivalent to prevent reverse engineering and bypass filters.
- Source Code Obfuscation - JS-Fuck transforms standard JavaScript code into a functional equivalent using six specific characters to obfuscate the logic.
- JavaScript - Enables the execution of arbitrary logic by converting obfuscated strings into executable JavaScript functions.
- Prototype Chain Manipulation - Accesses deep internal language objects and global scopes through unconventional casting and type coercion.
- Dynamic Code Evaluation - Executes arbitrary code by accessing the Function constructor to evaluate strings as logic.
- Execution Context Global Scope Access - Retrieves the global object by invoking a function that returns its current execution context.
- Global Scope Retrieval - Retrieves the global object by executing a function that returns its current invocation context.
- JavaScript Execution Environments - Runs arbitrary JavaScript logic using a restricted six-character set.
- JavaScript Source Encoders - Transforms standard JavaScript source code into a functional equivalent composed of a minimal character set.
- Esoteric Programming Languages - Serves as an experimental language exploring the minimum character set required for complex JavaScript logic.
- Prototype-Based Object Retrieval - Retrieves native methods and constructors by indexing into arrays and accessing built-in prototypes.
- Type Coercion Techniques - JS-Fuck derives a full set of symbols by casting booleans, numbers, and native method definitions into strings.
- Minimalist Obfuscation Languages - Encodes arbitrary JavaScript logic using only six specific characters to bypass filters or hide code.
- Dynamic Runtime Evaluation - Implements the ability to evaluate strings as executable functions to run arbitrary logic without a global scope reference.
- Implicit Type-Coercion String Generation - Produces alphanumeric characters by casting booleans and numbers into strings via implicit type conversion.
- Filter Bypasses - Circumvents security filters that block alphanumeric characters by using an alternative encoded character set.
- Source Code Obfuscation - Hides JavaScript logic by transforming it into an unconventional format of six characters that is difficult for humans to read.
- Esoteric Languages - Esoteric style using only atomic parts of JavaScript.
- Security Utilities - Obfuscates JavaScript.
