This directory contains additional programs that we used to compute
hashes of all disk and memory blocks.

tct-cron        Script run from cron that collects data and sends
		it over the network to a drop-off host. This computes
		16-bit hashes which is enough to find out if data
		has changed, but not to recognize if a memory page
		is identical to a file block etc.

tct-cron-mem-128-4k This version computes 128-bit hashes of 4k pages
		from swap and memory. This is sufficient to recognize
		if a memory page is identical to a file block.

fshash          Computes MD5 hashes for successive file system
		blocks. By default, this command examines all
		currently mounted file systems.

ramhash         Computes MD5 hashes for successive blocks of physical
		memory.

swaphash        Computes MD5 hashes for successive blocks of swap
		space. By default, this command examines all currently
		active swap files.

tct-net		Utilities to transmit tct-cron's results over the
		network to a drop-off host.
