If you have configured wireless networks on your FreeBSD laptop/pc. You can use wpa_passphrase to make the password entries more obscure with the use of wpa_passphrase.

For example, given the following network entry in wpa_supplicant.conf:

network={
ssid=”BRUNO”
scan_ssid=1
priority=5
key_mgmt=WPA-PSK
psk=”Super Secret Plain Text Password”
}

wpa_passphrase can give you a psk entry that is more obscure:

$ wpa_passphrase BRUNO
# reading passphrase from stdin
Super Secret Plain Text Password
network={
ssid=”BRUNO”
#psk=”Super Secret Plain Text Password”
psk=536ac6450b5874686e33122f80d39ad633b59613389f123d149c76fef4f3c877
}

Just remember to delete the plain text version when you copy paste it into your config.
