	Adding SHA in addition to md5 sounds reasonable.  Dropping md5
would be somewhat premature at this point.

	Also, I am concerned that we never come to resolution on
issues of cryptographic technique before code is committed.  Most
recently, you checked in your PRNG proposal without really coming to
finalization on the discussion happening on krbdev.  

	It's certainly reasonable for you to make changes within your
own tree as security requirements from your employer change in
response to changing conditions.  It would probably be reasonable to
check in preliminary changes on a branch here.    I am not coninced
that we should be changing code that impacts the system
cryptographically without understanding the issues involved.

	This is just my opinion.  Also, I am not aware of side
discussions and private email; things may be verified more than I
know.
