The best way to protect your information is to encrypt it, using this simple yet very effective code you will be able to protect your information.
I have included all the files needed to encrypt your information on any PHP website.
I strongly recommend placing these files above the public facing folders
Public folders
/var/www/html/
/home/user/public_html/
Private folders
/var/encryption/
/var/key1/
/var/key2/
/var/key3/
/home/user/encryption/
/home/user/key1/
/home/user/key2/
/home/user/key3/
