++secure-delete for Debian
++------------------------
++
++The original package and debian versions prio to  3.1-5 contained a utility
++called smem that wiped memory. This utility seems to be of limited use and
++clashes with another binary of the same name, it is therefore renamed to sdmem.
++
++The source for secure_delete contains a 2.4 kernel module that turns every 
++call to unlink() into a secure remove, this module is not yet part of this 
++package for technical reasons. if you need it please "apt_get source 
++secure-delete" and build it yourself for now.
++
++Also note that securely wiping data from magnetic media is a difficult task and
++depends a lot on the filesystem in question (among other things). So there is no
++guarantee that this program will work in your configuration, but you can and
++should check for yourself by creating a loopback filesystem, mountig it and
++creating a file in it, then securely wiping it and grepping for it's contents in
++the loopback file:
++
++dd if=/dev/zero of=disk bs=4096 count=1024
++mke2fs disk
++losetup /dev/loop0 disk
++mkdir test
++mount /dev/loop0 test
++cd test
++for ((i=0; i<10000; i++))
++do
++	echo "ofenrohr" >> file;
++done
++cd ..
++umount test
++losetup -d /dev/loop0
++grep "ofenrohr" disk
++--> this should result in a "binary file disk matches"
++losetup /dev/loop0 disk
++mount /dev/loop0 test
++cd test
++srm file
++cd ..
++umount test
++losetup -d /dev/loop0
++grep "ofenrohr" disk
++--> this should not find anything
++
++Please make sure you use the correct filesystem type and options during the 
++mkfs!
++
++Another general problem of wiping data from disks is that most harddisks will
++occasionally mark a sector as "bad" and copy it's contents to a new location
++that the disk will pretend is at the original location. Since this is completely
++transparent, there is no way to access these sectors without touching the disks
++hardware. These sectors may then contain sensitive information that could be
++retrieved from the disk. If you want better security, use an encrypting
++filesystem (dm-crypt, loop-aes), and forget the key if you want to wipe it.
