Please, do not top post. It gets hard to follow the thread.
 Your Bang on! That is exactly my point in a previous
mail that never got to the list.
 Since one way hashes are not reversable as long
as the server knows what a UNIQUE hash means that is all that matters.
That is the methodology I find works well for me. Having said that it does mean
that one needs to query that .db for the meaning of each hash. However
caching answers speeds results on the server side. There is the chance
that someone can read what the hash means by reading the cache. Keep 
in mind they do have to be local which means they are already very
dangerous if that is the case. The damage is already done in my opinion
at that point.
