Using Base64 Encryption for PHP APIs

Submitted by Yorkiebar on
Introduction: This tutorial is on how to use encryption to transfer data securely, or at least more seucrely than plain text, from a Visual Basic application (or other source) to a PHP API.

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.
