This is an implementation and demonstration of a searchable encryption that prioritizes speed over hiding some properties, such as the size of the documents and the number of search results.
This is a proof of concept and should not be used in actual production environments.
It is generally recommended installing your Python packages in a Virtual Environment (venv).
The following packages are necessary to install petlib.
- Install python-dev:
sudo apt-get install python3.8-dev - Install libssl-dev:
sudo apt-get install libssl-dev - Install libffi-dev:
sudo apt-get install libffi-dev
The methods are logically divided over client.py, consultant.py and storage.py.
Common cryptographic functions and data representations are in models.py.
Finally, protocols for setup, uploading and searching are in protocols.py.
The file experiments.py contains some runtime, bandwidth and storage experiments.
The file demo.py is a Python script that starts a Graphical User Interface to play around with the implementation. In order to run the demo it is necessary to install PySimpleGUI.
In the /examples folder there are some simple text files that can be used for this purpose.
It is important to note that keywords are now extracted automatically from the files, but of course for an image file it
would make more sense to insert custom keywords.
