Shredo is a beautiful, functional file-shredding utility. It permanently shreds files, folders, and external volumes' contents to keep information secure and impossible for anyone to retrieve. Depending on security level and data-erase speed, you have 3 shredding methods at your disposal:
- 1-pass - Offers good security and quickest erase of data. It deletes access information to your files and writes random bytes over the data once.
- 7-pass - Slower speed, but better security than 1-pass. Writes over data 7 times, based on US Department of Defence (DoD) 5220-20 M standard algorithms.
- 35-pass - Slowest, but offers the best security. Erases file access info and writes over the data 35 times, based on the Gutmann method for deletion.
- Select shredding method for Secure Trash erase, either via popover or by setting default shredding method in Preferences to skip the popover selection step
- Added "Quit app when done shredding" option in Preferences
- Start shredding files by just pressing Return on your keyboard
- Other shortcuts are available, for example:
◦ Command+Shift+Delete - starts Secure Empty Trash
◦ Command + Up Arrow - changes UI layout
◦ Command + Comma - shows Prefs
