Diese Webseite bietet eine interaktive, deutschsprachige Oberfläche zum „Obfuskieren“ von JavaScript-Code. Sie richtet sich an Entwickler, Agenturen und Interessierte, die die Funktionsweise von Code-Transformationen kennenlernen möchten, ohne produktiven oder unsicheren Code zu verbreiten.
Hauptfunktionen:
- Live-Preview: Sofortige Vorschau der Ausgabe beim Tippen
- Mehrere Methoden: Base64, XOR, URI-Escape, einfache Formatierung
- Erweiterte Optionen: Code in IIFE einpacken, Minify, Header-Kommentar hinzufügen, Eval in Vorschau deaktivieren
- Copy & Download: Ausgabe als Text- oder JavaScript-Datei kopieren oder herunterladen
- Agentur-Look: Modernes, übersichtliches Design mit Glas-Effekten, Farbverläufen und flexibler Layoutstruktur
