My college has a WPA2 Enterprise network, which I can connect to on my Pi after configuring the network in wpa_supplicant.conf.
I don't want my Wi-Fi password stored in plain text, so I use
echo -n $password | iconv -t utf16le | openssl md4 to hash it, and then store the MD4 hash instead of the plain text password in the file.
I wrote a Bash script that adds the config and hashes the password, which a lot of students have used to connect their Pis to the network. It's always worked, except for someone who has a password longer than 14 characters. That's great for security, but it causes problems with the MD4 hash algorithm.
wpa_passphrase won't work because it generates a PSK for a WPA-PSK network. My school's network is WPA-EAP, which requires a separate username and password, and is why I've been using NTLM password hashing instead.
Is there a way to hash passwords in the wpa_supplicant.conf file that are longer than 14 characters? I've tried hashing only the first 14 characters of the password, or an empty string, but neither of those work.
