RE: MD5 x SHA-1

["Brian A Kee" <bkee () lurhq com>]

In my experience better is relative.

I will assume that you are meaning which is more secure.

Everything that I have read states that SHA-1 is the more secure hashing
algorythm. They also state that there is a performance cost associated with
this algorythm compared to MD5.

I have never really taken the time actually test what the performance cost
difference is, nor whether or not the algorythm is actually more secure.

This information can be found in various textbooks including Applied
Crytpography. I beleive that this is referenced in many vendor IPSEC
configurration guides.

In my experience, both seem to be as good an the other. I have configured
many a VPN where I have chosen either algorythm. I have been equally happy
with both applications.
