Mysql (MariaDB) with PDO
Introduction
Some of my database stuff is shown.
File structure is as follow:
> www.public.com >> index.php >> php_folder >>> class.php >>> loadData.php > passwords >> public.com_passwords.txt
The folder www.public.com is connected to the internet, and passwords is not available from the internet. The password files contains the passwords and login credentials; this file is extremey simple. Only the password:
thisIsMySecretPassword
Establishing connection to the server
Store the password into a secure place, thus above the the www directory. Php can access that.
The file index.php includes the php file
<?php
include ('php/loadData.php');
$aa = $conn -> getData();
$bb = $conn -> getImages();
?>
First, it connects to the database and then reads some data. No logging in in this example.
The password is outside the internet, but be aware that if the hacker can upload a php file, it might be able to access the secret password.
The code is shown as images, but is also downloadable here as a text format. Add php code tags around it; see the images.
Log a user
SSL connection. Hash and salt. Php password hashing functions and mainly password_hash
with password_verify
.
Check the database if the username is exists. If it is, fetch the password hash and compare that against the user inputted hash.
