Permanent Eraser

2.8.0

Securely delete files.

Overview

Permanent Eraser allows you to securely delete files. When you normally delete your files in macOS / OS X, the operating system is only forgetting where those particular files are placed, while the data still physically remains on the drive. Beginning with OS X 10.3, Apple enhanced its security by introducing the Secure Empty Trash feature, which follows the U.S. DoD pattern of overwriting data seven times.

Permanent Eraser provides additional wiping methods such as the 3-pass DoE or 35-pass Gutmann algorithms. This utility overwrites your data multiple times, scrambles the original file name, and truncates the file size to nothing before Permanent Eraser finally unlinks it from the system. Once your data has been erased, it can no longer be read through traditional means.

  • Implements the Gutmann Method via SRM to remove files
  • Erases the files in your Trash
  • Erases CD-RWs and DVD-RWs
  • Erases files dropped on the application icon
  • Provides a warning dialog before files are erased (Press the Option key to bypass this warning)
  • Universal Binary
  • Localized for English, German, French, Dutch, Italian, Swedish, Traditional Chinese, and Welsh

What's new in Permanent Eraser

Version 2.8.0:
  • Requests authorization to erase write-protected files.
  • Reduced the app size.

Great App does what it says! There definitely needs to be a check box in the preferences to keep the app open even when its not trashing files. So that you can drop files onto its icon in the dock. It would also be great if you could add an Erase Free Space option, as well as for other drive selection.

Valuable utility for those of us luddites stuck with spinning hard drives. Pro-tip for dummies like me: this app works by dragging and dropping files onto its icon in the Applications folder or in the Dock or the Finder sidebar; launching the app by double clicking or via the Dock will only start it up to delete items in the Trash. Once it's completed erasing, the app quits automatically.

Still a wonderful application for hard drives. Not used on my SSDs but certainly now and then on hard drives used for backup. And it is still free after all those years. Thanks to the developer!

This developer has kept his program alive and well for many years now. Always used it; always loved it! Good coder, great app! I gave it 5 stars, but the menu only records 4 and a half.

Great free app!! Works as described by developer. As mentioned, this is for mechanical hard drives only. Do not use on SSD.

Agreed. This app checks to see if the file is on an SSD, and if so, it does not perform multiple writes, which would not work properly if the drive has wear leveling enabled. PE is best used for computers which still have older, mechanical hard drives.

SSDs have GarbageCollection and WearLevelling, so you don't need to erase deleted files: it is done automatically.

thanks for your answer. But everywhere it´s said that if you empty your trash, the files can be restored and that I don´t want. Didn´t find a solution yet

As I said, there is nothing to restore after the two mechanisms I mentioned. They are erased.
The reason why you should not do an erase (extra) on a SSD is it means a write with zero's. And every write is one nail on the coffin: the writes are wear. But in normal use SSDs have longer life than a HDD.

The reason Apple removed 'Secure Empty Trash' in El Capitan is, in part, related to the nature of SSDs (Solid State Drives), which are becoming ubiquitous in computing devices. Because of the nature of how SSDs write and erase data, there is no guarantee that a 'Secure Erase' actually removes the targeted data. This problem was written up as a CVE (Common Vulnerabilities and Exposures), CVE-2015-5901. You can read about the problem here: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-5901 The article linked above includes 'References' to two further articles at Apple about the situation. NOTE: There is no reason to assume, to my knowledge, that 'Permanent Eraser' is going to permanently 'Secure Empty Trash' either, due to the same situation. Instead, it may simply be needlessly further shortening the life of your SSD compared to ordinary 'Secure Empty Trash.' Here are a couple articles about the situation as well as related information: How to Use “Secure Empty Trash” Equivalent in OS X El Capitan http://osxdaily.com/2015/10/12/secure-empty-trash-equivalent-mac-os-x/ How to replace El Capitan's missing Secure Empty Trash http://www.macworld.com/article/3005796/operating-systems/how-to-replace-secure-empty-trash-in-os-x-el-capitan.html

If one wants to protect their data on an SSD, encrypt your drive. The older methods to overwrite data on mechanical hard drives do not apply to newer SSDs. Aside from some manufacture methods to wipe the entire drive, there is not (currently) a reliable way to erase a specified filed on SSD.

I drag it to Finder's toolbar so I can easily secure delete files from any Finder window (I do the same with AppCleaner too).

I dragged the PE app icon to the Dock. Now, I merely drop the target file/folder on the PE Dock icon, and voilà, it erases according to the established preference setting.
