Re: MD5 versus SHA
Earlier I posted the following information.
It has been pointed out that the DES code I used
probably is showing caching effects which are
unrealistic for comparison to the MD5 code.
Running DES over a 2 M byte file in /tmp (RAM), I got the
Sun 10/51 5.7 Mbps
Sun 20/61 7.5 Mbps
Sun 20/71 9.5 Mbps
I'm not sure if the desCore numbers are realistic, as a result.
