This is a false dichotomy:

    Don't roll your own password storage; use a secure password hash, 
such as Argon2i.

Such a term is only needed because you're trying to fit this into a 
pattern that puts you in a linguistic straitjacket. By reframing the 
problem - and the problem is not encryption, or hashing, it's that people 
aren't using Best Practices - the need falls away.
