Yes, the existing encryption is encoded in the hash and that encryption
is used, obviously, to compute the hash for the password just entered.

Yes.

Correct.

Yes.

You can:

        - set the default (used for new)
        - deprecate some (or allow some)

If someone changes their password and they are using a deprecated algrithm
their new password will be encoded with the default.
