🔑 Cryptographic License Enforcement

PHP Software Licensing Engine

Control software distribution, protect subscription revenue, and bind commercial PHP applications to authorized domains, server IPs, and expiration dates.

Supported Licensing Capabilities

🌐 Domain & Subdomain Locking

Bind applications to specific client domains or allow unlimited subdomains via wildcard patterns (*.clientdomain.com).

Enforced at runtime via HTTP HOST headers

🖥️ Dedicated Server IP Binding

Restrict execution strictly to designated IPv4 / IPv6 addresses, preventing clients from duplicating deployments across unauthorized hardware.

Enforced at socket & network interface level

⏳ Expiration Dates & Subscriptions

Enforce recurring subscription models or time-limited trials. Applications automatically refuse execution upon license expiry.

Supports automated cron renewal / refresh

🔐 Ed25519 Mathematical Verification

Licenses are verified using Ed25519 digital signatures. Any modification of the license file immediately invalidates cryptographic integrity.

Zero risk of manual tampering or patching

Autonomous & Offline Verification

Because license keys contain self-contained Ed25519 digital signatures, the PHPcube Loader verifies license validity directly on the local server in microseconds without requiring a continuous outbound internet connection for every HTTP request.

High Reliability: Even if your license server experiences downtime or your client server operates inside a firewalled private network, valid signed licenses execute without interruption.
