Preparation for this recipe consists of installing the ssdeep package in pip. The installation is a little tricky and does not always work on Windows. Instructions can be found at https://python-ssdeep.readthedocs.io/en/latest/installation.html.

If you only have a Windows machine and it does not work, then one possible solution is to run ssdeep on an Ubuntu VM by installing pip with this command:

pip install ssdeep

In addition, download a test file such as the Python executable from https://www.python.org/ftp/python/3.7.2/python-3.7.2-amd64.exe.
