Re: Encyption/Decryption of Form Fields in CakePHP 3

You can try to use my CipherBehavior plugin.

Hello,

I was hoping someone could help with my task. It should be "relatively" simple: I want to have some form-fields encrypted when they are added/edited and decrypted when they are looked up by cake.
Here is the code that works for me in v2.7.2:

core.php:

Configure::write('Security.key','secretkey');

app/Model/Patient.php:

public $encryptedFields = array('patient_surname', 'patient_first_name');

public function beforeSave($options = array()) {
    foreach($this->encryptedFields as $fieldName){
        if(!empty($this->data[$this->alias][$fieldName])){
            $this->data[$this->alias][$fieldName] = Security::encrypt(
                $this->data[$this->alias][$fieldName],
                Configure::read('Security.key')
            );
        }
    }
    return true;
}

public function afterFind($results, $primary = false) {

    foreach ($results as $key => $val) {
        foreach($this->encryptedFields as $fieldName) {
            if (@is_array($results[$key][$this->alias])) {
                $results[$key][$this->alias][$fieldName] = Security::decrypt(
                    $results[$key][$this->alias][$fieldName],
                    Configure::read('Security.key')
                );
            }
        }
    }
    return $results;
}

As I understand it I have to replace $this->data[] with the generated entities for the model and the afterFind method with virtual fields, but I just can't put it all together.

Thanks for any pointers
