What problem? Based on what you describe above, the only issue that
seems to be here is in iwlist (which has been obsolete for years) does
not know how to display the correct name for the SHA256-based key
management option.. I'm not sure how any of this would have anything to
do with wpa_supplicant.

It does not look like hostapd would currently expose this in a
convenient way.
