ssh keys - Python container troubles -


basically trying generate json list of ssh keys (public , private) on server using python. using nested dictionaries , while work extent, issue lies displaying every other user's keys; need list keys belong user each user.

below code:

def ssh_key_info(key_files):     f in key_files:             c_time = os.path.getctime(f)  # gets creation time of file (f)             username_list = f.split('/')  # splits on / character             user = username_list[2]  # assigns 2nd field frome above spilt user variable              key_length_cmd = check_output(['ssh-keygen','-l','-f', f])  # run ssh-keygen command on file (f)              attr_dict = {}             attr_dict['date created'] = str(datetime.datetime.fromtimestamp(c_time))  # converts file create time string             attr_dict['key_length]'] = key_length_cmd[0:5]  # assigns first 5 characters of key_length_cmd variable              ssh_user_key_dict[f] = attr_dict             user_dict['ssh_keys'] = ssh_user_key_dict             main_dict[user] = user_dict

a list containing absolute path of keys (/home/user/.ssh/id_rsa example) passed function. below example of receive:

{ "user1": {     "ssh_keys": {         "/home/user1/.ssh/id_rsa": {             "date created": "2017-03-09 01:03:20.995862",              "key_length]": "2048 "         },          "/home/user2/.ssh/id_rsa": {             "date created": "2017-03-09 01:03:21.457867",              "key_length]": "2048 "         },          "/home/user2/.ssh/id_rsa.pub": {             "date created": "2017-03-09 01:03:21.423867",              "key_length]": "2048 "         },          "/home/user1/.ssh/id_rsa.pub": {             "date created": "2017-03-09 01:03:20.956862",              "key_length]": "2048 "         }     } },

as can seen, user2's key files included in user1's output. may going wrong, pointers welcomed.

thanks replies, read on nested dictionaries , found best answer on post, helped me solve issue: what best way implement nested dictionaries?

instead of dictionaries, simplfied code , have 1 dictionary now. working code:

class vividict(dict):     def __missing__(self, key):          # sets , return new instance         value = self[key] = type(self)() # retain local pointer value         return value                     # faster return dict lookup  main_dict = vividict()  def ssh_key_info(key_files):             f in key_files:                 c_time = os.path.getctime(f)                 username_list = f.split('/')                 user = username_list[2]                  key_bit_cmd = check_output(['ssh-keygen','-l','-f', f])                 date_created = str(datetime.datetime.fromtimestamp(c_time))                 key_type = key_bit_cmd[-5:-2]                 key_bits = key_bit_cmd[0:5]                  main_dict[user]['ssh keys'][f]['date created'] = date_created                 main_dict[user]['ssh keys'][f]['key type'] = key_type                 main_dict[user]['ssh keys'][f]['bits'] = key_bits
