Important: Never store the key in the encrypted file!

HOW IT WORKS FOR VISITORS

When visitors access your encrypted PHP file:

The encrypted PHP file is executed on the server, not in the browser
The server decrypts the code in memory using your secret key (stored separately)
The decrypted PHP code is executed normally on the server
Only the output (HTML, text, etc.) is sent to the visitor's browser
The visitor never sees the encrypted source code or the decryption key

SECURITY INFORMATION

The system uses AES-256-CBC encryption combined with a random IV for each encryption. Only those with the secret key can decrypt the content. This encryption helps protect code from direct viewing.

For maximum security, always store your encryption key separately from the encrypted files!

❌ Cannot decrypt without key

Even with the encrypted file, no one can recover the original source code without the secret key.

🔒 Strong encryption

Uses the high-security standard AES-256-CBC algorithm.

🛡️ Anti reverse engineering

The encrypted code is stored as ciphertext + IV and is only decrypted in memory during execution.

🌐 Browser compatible

Visitors will see the normal output, as the decryption happens on the server.
