Shred is a Mac app that allows you to securely erase files, meaning that if they are ever recovered (by specialist software) their content will be useless. For added security, data can be overwritten up to 35 times and the name and date of the file/folder changed to random values. Both files and folders can be added to the list to be shredded. Files will have their content overwritten and then the file will be deleted. Any folders in the list will be searched and any files residing in them will be shredded. The folder will then be deleted.
