login.py imports http_basic in ch07a and ch07b but in the latter , http_digest is used , generating the below error

from api import admin, login, profile, auction, bid
File "./api/login.py", line 13, in
from security.secure import authenticate, get_password_hash, http_basic
ImportError: cannot import name 'http_basic' from 'security.secure' (./security/secure.py)

can i raise a PR to fix this ?
