Thanks Mike and David for the discussion.  It's not WAY more than I wanted
to know, but I could use some help in applying all my new found knowledge ;-)

Should I be using CFHASH for has hashing?  I've heard lots of criticism of
CFENCRYPT, but I don't remember seeing any for CFHASH.  Do you know if it
uses MD5, SHA, and RIPE-MD, or something else?  If not CFHASH, then can you
recommend a CF implementation for hashing?

Is there a CF version of Blowfish do can recommend?  I saw the 12
implementations of blowfish at
http://www.counterpane.com/blowfish-download.html, but I don't know how to
integrate any of them with CF, other than maybe writing a CFX tag, which I
don't know how to do.  I also found CF_ENCRYPT by Jim Fuller in the tag
gallery ($150), but thought there might be a free CF version somewhere.

Finally, what does "non-reduced-round" mean when you said "here are is
known crytanalysis against non-reduced-round Blowfish"  Is this 20 round?

thanks,
