Chris Hartjes has a new post to his blog today focusing on using a bit of the CakePHP framework's functionality from the command line.

I'm porting a spaghetti-PHP application over to using CakePHP I am moving their existing authorization system over to using Cake's Auth component. Of course, they are storing all their passwords in plaintext in the user account table, so I needed an easy way to convert all the existing passwords over to be encrypted using the same hash that Auth would use.

With the help of the shells and tasks that the framework makes availiable, he's able to make a simple 24 line class (EncryptPasswordShell) that extends the Shell object and loops through the data to push it back into the database in the correct password format.
