wpa_passphrase8

Utility for generating a 256-bit pre-shared wpa key from an ascii passphrase

Usage

wpa_passphrase ⟨ssid⟩ [passphrase]

Overview

The wpa_passphrase utility is a small program for generating a 256-bit pre-shared WPA key from an ASCII passphrase and a given SSID. The output is formatted for inclusion in wpa_supplicant.conf(5).

If wpa_passphrase is called with only an SSID as argument it will prompt for a passphrase on standard input.
