Introduction to hashing passwords in PHP (5.5+) [↗]
The methods considered secure a few years ago, are now obsolete/insecure due to ever increasing computing power and advanced techniques. And unless you are well versed in the area of cryptography and security, it is never a good idea to roll your own security mechanisms.
It’s been a while since I needed to hash any passwords with PHP (I’ve been working on an Intranet with Active Directory authentication for the past few years), so I went looking for a best practice guide and found this. Seems like good advice to use PHP’s built-in functions.
