MD5 in PHP [Why? How? Explained]

Submitted by Yorkiebar on
Introduction This tutorial is on using MD5 encryption in PHP. Why MD5? MD5 is built in to PHP and is only a one way encryption. This means that even if someone was able to gain access to an encrypted md5 string, called an 'MD5 Hash', it is unlikely they would be able to convert the hash back in to the original plain text string. Decryption: Decryption in most cryptography languages essentially work by using the reverse algorithm to the encryption algorithm used by the cryptography method in question.

In this tutorial you will learn: 1. How to make Arrays as Class Data Member? 2. Why to use arrays as attributes of the class? 3. How to make array of objects? 4. C++ syntax Arrays can also be the data members of the class, just like integer, float and other data type integers we can also define an array as the data members.

Introduction: This tutorial is on how to upload POST data to a PHP file on a web server or localhost through Visual Basic .NET. Why POST? POST is the method used to upload sensitive data such as passwords, as opposed to using the PHP GET method which will simply show all data in the URL bar; GET - http://www.website.com/page.php?password=ThisIsMyGETPassword POST - http://www.website.com/page.php Both example sites would receive the same information, but the POST one is undercover and therefore slightly more secure. Why Only Slightly More Secure?

Constant Data Members and Objects

In this tutorial you will learn: 1. What are Constant Data Members? 2. What are Constant Objects? 3. Why to use Constant Data Members and Objects? 4. How to use Constant Data Members and Objects? 5. C++ syntax What are Constant Data Members? The data members that are once initialized and can never be changed are called constant member functions. Constant member functions are just like normal data members, only ‘const’ key word is added before writing the data type of the data member of the class.
