How To Encrypt Data in Oracle Using PHP

Part of the Oracle Technology Network's Oracle + PHP Cookbook series, this article teaches exactly what the title suggests: how to encrypt data in Oracle using PHP. The trick I use in this example is to define your own stored routines that will handle the encryption. This securely puts the encryption information hidden in the database and you only need to call the routines in your queries in order to invoke them using PHP.

You can read it online at http://dmcinsights.com/newsletter.php. The next newsletter should go out in a few days.
