I don't see why this is better than the method already used, since you
would have to use a different call to make such strings.  In the end
it's up to the application to manage these secrets.

But what about the storage the string is copied from?  Really, keeping
secrets is up to the application.  I think this is overkill, and won't
really help naive users keep their secrets.
