Core Workflow

PurePHPEncryptor follows a simple three-step workflow to protect your PHP applications:

Generate a License

Create a hardware-bound license file for your customer. Specify constraints like hostname, IP address, expiration date, and more.

bash 
ppe license:generate \
    --licensee="Acme Corp" \
    --hostname=prod.acme.com \
    --expires=+1y \
    --output=acme-corp.ppe

Encrypt Your Code

Run the encryptor on your source directory. All PHP files are encrypted with AES-256-GCM and bound to the license.

bash 
ppe encrypt \
    --license=acme-corp.ppe \
    src/ \
    dist/

Deploy

Ship the encrypted files along with the runtime and license. Your customer runs PHP normally—the runtime handles decryption transparently.

bash 
# Your customer's server
php index.php  # Just works!

Requirements

PurePHPEncryptor has minimal requirements and works on virtually any PHP environment:

Requirement Version Notes
PHP 8.0+ Both CLI and web SAPI supported
OpenSSL extension Any Enabled by default since PHP 5.3
zlib extension Any For compressed encrypted files (optional)
json extension Any Built into PHP 8.0+

No special extensions required! Unlike ionCube or Zend Guard, PurePHPEncryptor works on any standard PHP installation. Perfect for shared hosting.
