This is a demo for a simple example of XOR encryption. The code belongs to a tutorial that you can find here.
- PHP 7.x
- composer (only needed to install dependencies for the unit tests)
- npm (only needed to install dependencies for the demo)
In the src folder you will find the EncryptionUtil.php file.
This class contains two static methods, encrypt and decrypt. Both methods take two strings as parameters, a message
and a key. The message can be encrypted (for use with the decrypt method), or clear text (for use with the encrypt method).
EncryptionUtil::encrypt("message", "key");
EncryptionUtil::decrypt("encryptedMessage", "key");I would recommend encoding the encrypted text into base64 or something similar to avoid it containing characters that
could be filtered out if posted online. You can se an example of this in the do.php file in the demo directory.
