This tutorial teaches you how to build a secure users registration and log in system whereby users of your websites will be able to create their accounts, log in with their valid account information so as to access their various accounts on your server without SQL Database using Ajax, Jquery and PHP.
The system is secured in the sense that, the passwords of all the users within the system are first encrypted with an MD5 Algorithm and all the other information of the users which are Fullname, Username, Email Address are encrypted with Base64 Encryption including the passwords which was first encrypted with an MD5 Algorithm and all these information are saved to an MS-Word file.
This MS-Word file can not be opened by any one including the admin of the system because the encrypted users information in it are unready and so, MS-Word can not understand to ready or open it.
You have an option to change this file from an MS-Word document to any other type of file such as .txt file if you wish to see the encrypted users information when users sign-up.
You can make the change in the file named vpb_database.php. All other information you may need to make your changes are given as comments in the codes.
Users information such as username and email addresses which are unique within the system are validated during sign up process to avoid duplicates before they are saved to the specified file used as the system database.
This system is based on Ajax, Jquery and PHP. Programs are written in a way that any one can easily understand and customize with good use of programming codes comments to ease usability.
To install the system on your server, simply download the zipped folder containing the required files, extract and upload the folder to your server and you are done to start using the system.
No form of configuration or setting is required or involved.
