Richkit

Richkit is a python3 package that provides tools taking a domain name as input, and returns addtional information on that domain. It can be an analysis of the domain itself, looked up from data-bases, retrieved from other services, or some combination thereof.

The purpose of richkit is to provide a reusable library of domain name-related analysis, lookups, and retrieval functions, that are shared within the Network Security research group at Aalborg University, and also availble to the public for reuse and modification.

Documentation can be found at https://richkit.readthedocs.io/en/latest/.

Requirements

• Python >= 3.5

Installation

In order to install richikit just type in the terminal pip install richkit

Usage

The following codes can be used to retrieve the TLD and the URL category, respectively.

• Retriving effective top level domain of a given url:

  >>> from richkit.analyse import tld
  >>> urls = ["www.aau.dk","www.github.com","www.google.com"]
  >>>
  >>> for url in urls:
  ...     print(tld(url))
  dk
  com
  com
  

• Retriving category of a given url:

  >>> from richkit.retrieve.symantec import fetch_from_internet
  >>> from richkit.retrieve.symantec import LocalCategoryDB
  >>>
  >>> urls = ["www.aau.dk","www.github.com","www.google.com"]
  >>>
  >>> local_db = LocalCategoryDB()
  >>> for url in urls:
  ...     url_category=local_db.get_category(url)
  ...     if url_category=='':
  ...         url_category=fetch_from_internet(url)
  ...     print(url_category)
  Education
  Technology/Internet
  Search Engines/Portals
  

Modules

Richkit define a set of functions categorized by the following modules:

• richkit.analyse: This module provides functions that can be applied to a domain name. Similarly to richkit.lookup, and in contrast to richkit.retrieve, this is done without disclosing the domain name to third parties and breaching confidentiality.

• richkit.lookup: This modules provides the ability to look up domain names in local resources, i.e. the domain name cannot be sent of to third parties. The module might fetch resources, such as lists or databasese, but this must be done in a way that keeps the domain name confidential. Contrast this with richkit.retrieve.

• richkit.retrieve: This module provides the ability to retrieve data on domain names of any sort. It comes without the "confidentiality contract" of richkit.lookup.

Run Tests on Docker

In order to prevent any problems regarding to environment, we are providing Dockerfile.test file which basically constructs a docker image to run tests of Richkit.

• The only thing to add is just MAXMIND_LICENCE_KEY in .github/local-test/run-test.sh at line 3. It is required to pass the test cases for lookup module.

Commands to test them in Docker environment.

• docker build -t richkit-test -f Dockerfile.test . : Builds required image to run test cases

• docker run -e MAXMIND_LICENSE_KEY="<licence-key> " richkit-test : Runs run-test.sh file in Docker image.

Contributing

Contributions are most welcome.

We use the gitflow branching strategy, so if you plan to push a branch to this repository please follow that. Note that we test branch names with .githooks/check-branch-name.py. The git pre-commit hook can be used to automatically check this on commit. An example that can be used directly as follows is available on linux, and can be enabled like this (assuming python>=3.6 and bash):

ln -s $(pwd)/.githooks/pre-commit.linux.sample $(pwd)/.git/hooks/pre-commit
