In this movie, we'll learn about encrypting passwords. …Hashing is the term for the process of taking a string of data and apply a …mathematical function to it to produce a unique string of output. …Which is known as a hash. Hashing is often used for encryption but …that's not its only use. For example, it can be used to create …unique identifiers or to quickly determine if a large amount of data has changed. …But what we're interesting in using it for is password hashing. …That is, applying an algorithm to a password, to generate an encrypted string. …Knowing an encrypting hash won't give away the password and the original …password can't be reverse engineered even with lots of computing power.…
And the hash that it generates for each password will be unique, so that it can …only be recreated by using the same password with the same hashing algorithm. …In short, the only way to have a password match will be to know the original …password and that's what we want. Now the most important rule about …

Q: This course was revised on 6/4/2013. What changed?
A: The old version of this course was 6 years old and it was time for a complete revision, using PHP 5.4. (The tutorials will work with any version of PHP and covers any differences you might encounter). The author has also added updated installation instructions for Mac OS X Mountain Lion and Windows 8. The topics and end project are the same, but the code is slightly different. It also addresses frequently asked questions from the previous version.

A: We added one movie called "Changing the document root in Yosemite," which helps the Mac installation run more smoothly.
