+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.
