Aladdin Systems is shipping Secure Delete, a data-deletion tool for Macs.

The utility completely and permanently erases selected files by overwriting them. It supports drag-&-drop, so files need only be dragged onto the application to be digitally destroyed. Such files cannot be recovered.

“Simply throwing a file in the Trash doesn’t ensure that a file can’t be retrieved again by someone going through your computer,” said Pauline Shumake, product manager. “It’s important to use Secure Delete to effectively remove private files so they don’t get into the wrong hands.”

The utility is available for download from Aladdin Systems. It will run on Mac OS 8.1 or later, and also on OS X. Registration costs $25.
