srm is a secure replacement for rm(1). Unlike the standard rm, it overwrites
|
|
the data in the target files before unlinking them. This prevents command-line
|
|
recovery of the data by examining the raw block device. It may also help to
|
|
frustrate a physical examination of the disk, although it's unlikely that it can
|
|
completely protect against this type of recovery.
|
|
|
|
srm uses algorithms found in "Secure Deletion of Data from Magnetic and Solid-
|
|
State Memory" by Peter Gutmann and THC Secure Delete (the overwrite, truncate,
|
|
rename, unlink sequence).
|
|
|
|
Please note that srm will only work on file systems that overwrite blocks in
|
|
place. In particular, it will *NOT* work on reiserfs or the vast majority of
|
|
journaled file systems. It should work on ext2, FAT-based file systems, and
|
|
the BSD native file system. On ext3, srm will try to disable the journaling
|
|
of data (please see the verbose output if this fails).
