Python routine to get a session ID from a FRITZ!Box

fritzsid.py

#!/usr/bin/env python

# Simple python2/3 routine to get a SID from a FRITZ!Box as it took me forever to figure this out

# If you don't have https set up, set the urls to http and remove the two verify options

# If you do have https set up, point the two verify options to the CA cert
# (unless your FB cert is publicly signed, then remove the verify options)

username = "YOUR_USER"

challenge = ElementTree.fromstring(get("https://fritz.box/login_sid.lua", verify='/path/to/cert.pem').text)[1].text

hash = md5("{}-{}".format(challenge, password).encode("UTF-16LE")).hexdigest()

response = "{}-{}".format(challenge, hash)

print(ElementTree.fromstring(get("https://fritz.box/login_sid.lua?username={}&response={}".format(username, response), verify='/path/to/cert.pem').text)[0].text)
