PHP Password Security
Richard Lord zeigt in dem Artikel PHP Password Security welche Möglichkeiten PHP bietet Passwörter sicher zu speichern.
There are a number of hashing algorithms in PHP, of which md5 and sha1 are the most commonly used. Unfortunately, neither is as secure as they were once thought to be. It would be better to use a more secure hash, and if you have the Hash engine in your PHP installation (included by default since PHP 5.1.2) then you have access to many more algorithms.
