The Modern PHP DRM & Code Protection Engine
Ultra-fast native Zend Engine C extension for Linux servers. Distribute commercial PHP scripts, Laravel modules, and client applications with zero-disk RAM execution, Ed25519 cryptographic signatures, and 0% CPU overhead.
Key features of the phpcube PHP encoder
Zero-Disk RAM Execution
Encrypted scripts decrypt directly into Zend Engine RAM structures. Never writes temporary files to disk, eliminating dump attacks.
Ed25519 Cryptography
Mathematically verified Ed25519 signatures ensure licenses cannot be forged or altered. Any byte manipulation causes immediate rejection.
Domain & IP Locks
Enforces single domain, wildcard subdomain (*.client.com), server IP, and expiration dates before execution begins.
Engineered for Linux
Built specifically for Linux x86_64 servers running aaPanel, Ubuntu, Debian, CentOS, AlmaLinux, Rocky Linux, and Docker containers.
How phpcube Protects Your Code
Original plain PHP source code is converted into encrypted binary blocks that only the native Zend loader can decrypt and execute in RAM.
