I'm writing a report on secure data destruction on Macs. I've looked into using the "Disk Utility" that is built into OS X, but I'm not sure what algorithms it uses. For my purposes I need them to be at least DOD 5220.22M compliant. I know that the utility can erase data using seven or thirty-five passes, but it does not specify which algorithm is used. Does anyone know whether Disk Utility achieves this level of security?
