Question

I am pretty new in python, and I have a problem I don’t know how to solve.

For example, I have this struct with members such as administrator, berit, etc:

DEFAULT_DATA = {
'administrator': {
    'name': 'Admin',
    'pw': 'secret',
    'is_author': False,
    'is_admin': True
}
'berit': {
     'name': 'berit',
    'pw': 'apa',
    'is_author': False,
    'is_admin': False
 }

This data is then accessible via a method this method:

def DefaultData():
"""Provides default data for Gruyere."""
 return copy.deepcopy(DEFAULT_DATA)

I want to do a md5 hash on the passwords so they are not in plaintext, but I have no idea how to access the fields such as ‘pw’ and reassign a new value in python.

Here’s a guess as to what it might be:

stored_data = data.DefaultData()
for member in stored_data:
   for field in member:
       if field=='pw':
           'pw' = md5.new(salt+pw).hexdigest()    // how do you access the value?

Answer 1

The values in stored_data are themselves dictionaries. Iterate over the values and apply your algorithm:

stored_data = data.DefaultData()
for data in stored_data.values():
    data['pw'] = md5(salt + data['pw']).hexdigest()

from pprint import pprint
pprint(stored_data)

Output

{'administrator': {'is_admin': True,
                   'is_author': False,
                   'name': 'Admin',
                   'pw': '33e7cb694fb6fb2f848af6774d9ff138'},
 'berit': {'is_admin': False,
           'is_author': False,
           'name': 'berit',
           'pw': '00c10978330d65eb0cb739a629b6ed15'}}
