In addition to the Secure file deletion options currently in CCleaner: Simple Overwrite -1 pass; DOD 5220.22-M -3 passes; NSA - 7 passes; and Gutmann - 35 passes. I was wondering if these delete/wiping methods listed below could be added to the options already available to choose from in options. these methods would be a great addition to the others because they are fast and quite secure.
Schneier (7-Pass)
This method is based on Bruce Schneier's algorithm. It relies on a cryptographically secure random number generator to wipe with random data. It will overwrite a file 7 times. It is very secure and should be used for private files.
Gutmann Subset (5-Pass)
This method is a subset of the Gutmann 35-Pass method. It takes the most effective patterns from the 35-Pass method and breaks them down to only 5 passes. It is secure and should be used for general files.
