Laravel Class Obfuscator

Production-grade CSS & HTML class masking for Laravel applications. Deterministically hashes CSS selector names and Blade class attributes using HMAC-SHA256 Base62 tokens. Zero runtime database or cache overhead.

⚡ Zero Overhead

Class mappings are pre-compiled at build time via Node AST scanner (php artisan classobf:build).

🔑 Deterministic Hash

Same secret key = identical obfuscated tokens across builds and microservices.

🛡️ Whitelist Support

Preserve dynamic JavaScript classes via glob patterns (data-*, is-*).
