Don't use / delimiters for the substitute,
use some character that would not be in the encrypted password charset.
Maybe ':' maybe ',' maybe ?????

Looks like editing a passwd type file.
You might wish to be more specific.
What if you have a bill and billy?

sed -e "/^bill:/s,${NEWSTORE},${NPASS},g" /tmp/temp

And to make sure you are only changing the passwd field:
(maybe there is another JvHCdEMzDegPI on the line

)

sed -e "/^bill:/s,^$[^:][^:]*:$${NEWSTORE},\1${NPASS}," /tmp/temp

Why the global "g"? You expect more than one $NEWSTOR per line?
