Short answer is, I believe, yes.  But (to me), ${$trashmd5p}{key} would be 
more clearly written as:

	$trashmd5p->{key}

you won't get a 2nd copy of the entire hash which is what you're doing when:

my %trashmd5=%$trashmd5p;

(caveat: not knowing what else you might be doing with the contents of 
$trashmd5p, there might be better / other solutions too).


Cheers,
