Building an Open-Source Payload Obfuscator with React & Vite

The author built an open-source, client-side payload obfuscation tool using React 18, Vite, and Tailwind CSS to address the tedium of manually evading static analysis engines during security testing. The tool supports five languages and offers multi-layer transformations including variable randomization, string encoding, dead code injection, and XOR encryption wrappers. A real-time Shannon Entropy meter helps users keep obfuscated payloads in a moderate entropy range to avoid triggering heuristic scanners.
