PHP Code Encryption Virtualization Obfuscation Protection

No extension required, native virtualization source protection.
Complete obfuscation and restructuring of code data with optional domain and runtime restrictions.

Encrypt PHP Files Now

Supports encryption for popular PHP frameworks (we only encrypt functions and methods within PHP files)

PHP Encryption Technology Demo

This demonstrates our encryption technology principles - disclosure does not mean encrypted code can be easily reversed

Control Flow Obfuscation

Uses Switch-Case to completely shuffle control flow, making logic hard to trace.

Variable Obfuscation

Obfuscates local variables to random high-bit ASCII characters, making code hard to read.

Anti-Debug Protection

Blocks CLI, xdebug, inserts anti-debug traps to prevent analysis.

Virtualization

Multi-layer compression and obfuscation with gzinflate dynamic execution.

🔒 VM Encryption (8-Layer)

PHP interpreter rebuild with dual XOR + string reversal + compression + substitution + noise + shuffling.

Remote Loading

Core code on server, only loader locally. Even if leaked, source is protected.
