Re: MD5 versus SHA

	 The following was forwarded at Bill Simpson's request.
	 These updated MD5 numbers appear in a Sigcomm '95 submission,
	 which is not being widely distributed until the notifications
	 (at Sigcomm's request). The SHA and DES performance figures
	 will appear in the updated publication, presuming acceptance.

	 Sun 10/51	34 Mbps		37 Mbps		19 Mbps		20 Mbps
	 Sun 20/61	36 Mbps		38 Mbps		23 Mbps		29 Mbps
	 Sun 20/71	54 Mbps		57 Mbps		29 Mbps		37 Mbps
	 So in speed:
	 	MD5 > DES > SHA

But we know that DES can be done at at least 1Gbps in hardware.  One of
the points of the draft that was circulated a while back was that MD5
was *inherently* unable to run at that speed.  Or am I missing something?
