Is there a reason that there are multiple versions of 
md5/sha1/sha256/etc in the source tree?  There are versions in at least 
three places (lib/libmd, sys/kern/crypto, and crypto/openssl/crypto).  I 
think md5 is located in a few other places as well.

It seems if these could be centralized, then it would be easier to have 
assembly accelerated versions for each platform, or better yet to 
utilize crypto hardware.

I was just curious.
