There's an RFC and followup Sigcomm paper that focuses on the data
touching overheads and speeds of MD5 in particular:

	"Report on MD5 Performance"
    	J. Touch, RFC-1810, ISI, June, 1995.
	available lots of places, also cached at:
	http://www.isi.edu/touch/pubs/rfc1810.html

	"Performance Analysis of MD5"
	J. Touch, Proc. Sigcomm '95, Boston, pp. 77-86.
