I often use it when assigning new WPA keys to new users on my FreeBSD
(and hostapd) based access points.
Instead of having to generate all the 256-bit pre-shared WPA keys from
ASCII passphrases at runtime (cpu intensive operation when you have
many keys configured), I just call wpa_passphrase with the given SSID,
enter the ASCII passphrase and it gives me a static 256-bit key in
This furthermore allows me to give both the ASCII passphrase and the
256-bit pre-shared WPA key to any given user along with proper
The last part is especially helpful since quite a few vendor specific
WPA configuration utilities for that "other" operating system accepts
either an ASCII passphrase _or_ a WPA pre-shared key, meaning I would
have to guess which vendor specific piece of software a given user
has, and hand him/her either an ASCII passphrase or a WPA pre-shared
key based on my guess.
