How does it work?

Use either the encoder tool or our online encoder to encrypt your PHP files. Then upload the encrypted files to your web server.

A PHP extension must be installed on the web server. This performs on-the-fly decryption for the PHP engine.

Pay Just Once

Pay Just Once

You only need to buy a licence for the period of time that you want to encrypt your code. After that your code remains encrypted and keeps on working... forever.

Our pricing structure is designed to be fair and cost-effective. And our customers agree.


Proper Encryption, Not Obfuscation

Proper Encryption, Not Obfuscation

PHPshadow encrypts your code using a proper AES-based algorithm to give you maximum protection.

We do not use obfuscation, which is a very weak mechanism because it is easily reversible.
