dictature 0.9.4

dictature -- A generic wrapper around dict-like interface with mulitple backends

Dictature

A wrapper for Python's dictionary with multiple backends.

Installation

pip install dictature

Dictature usage

This package also includes a class that allows you to use your SQLite db or any backend as a Python dictionary:

from dictature import Dictature
from dictature.backend import DictatureBackendDirectory, DictatureBackendSQLite

# will use/create the db directory
# dictionary = Dictature(DictatureBackendDirectory('test_data'))
# will use/create the db file
dictionary = Dictature(DictatureBackendSQLite('test_data.sqlite3'))

# will create a table db_test and there a row called foo with value bar
dictionary['test']['foo'] = 'bar'

# also support anything that can be jsonized
dictionary['test']['list'] = ['1', 2, True]
print(dictionary['test']['list'])  # prints ['1', 2, True]

# or anything, really (that can be serialized with pickle)
from threading import Thread
dictionary['test']['thread'] = Thread
print(dictionary['test']['thread'])  # prints <class 'threading.Thread'>

# and deleting
del dictionary['test']['list']  # deletes the record
del dictionary['test']  # drops whole table

Currently, the following backends are supported:

• DictatureBackendDirectory: stores the data in a directory as json files
• DictatureBackendSQLite: stores the data in a SQLite database
• DictatureBackendMISP: stores the data in a MISP instance

Transformers

You can also use transformers to change how the values are stored. E.g. to encrypt data, you can use the AESTransformer (which requires the pycryptodome package):

from dictature import Dictature
from dictature.backend import DictatureBackendDirectory
from dictature.transformer.aes import AESTransformer

name_transformer = AESTransformer('password1', True)
value_transformer = AESTransformer('password2', False)

dictionary = Dictature(
    DictatureBackendSQLite('test_data.sqlite3'),
    name_transformer=name_transformer,
    value_transformer=value_transformer
)

Currently, the following transformers are supported:

• AESTransformer: encrypts/decrypts the data using AES
• HmacTransformer: signs the data using HMAC or performs hash integrity checks
• PassthroughTransformer: does nothing
• PipelineTransformer: chains multiple transformers
