Although I previously agreed to this change, I'm really not convinced it
is necessary.  encrypted keys don't create new trusted or user keys,
they only use existing keys to encrypt/decrypt encrypted
keys(instantiate,read).  Key names, user or otherwise, should be left up
to the person creating them.
