Overview
|
|
--------
|
|
|
|
.. important::
|
|
|
|
This demo requires connecting to a running network. By default the demo is hardcoded to connect to the :doc:`local demo fleet </demos/local_fleet_demo>`.
|
|
|
|
|
|
This demo is an example of a NuCypher decentralized network allowing Alice to share
|
|
data with Bob using proxy re-encryption. This enables the private sharing of data across public consensus networks,
|
|
without revealing data keys to intermediary entities.

+======+===========+==============================================================================================+
|
|
| 1 | Alice | Alice sets a Policy on the NuCypher network (2-of-3) and grants access to Bob |
|
|
+------+-----------+----------------------------------------------------------------------------------------------+
|
|
| 2 | Alice | Label and Alice's public key provided to Bob |
|
|
+------+-----------+----------------------------------------------------------------------------------------------+
|
|
| 3 | Bob | Bob joins the policy with Label and Alice's public key |
|
|
+------+-----------+----------------------------------------------------------------------------------------------+
|
|
| 4 | Enrico | A data source created for the policy |
|
|
+------+-----------+----------------------------------------------------------------------------------------------+
|
|
| 5 | Enrico | Each plaintext message gets encrypted by Enrico, which results in a messageKit |
|
|
+------+-----------+----------------------------------------------------------------------------------------------+
|
|
| 6 | Bob | Bob receives and reconstructs Enrico from the Policy's public key and Enrico's public key |
|
|
+------+-----------+----------------------------------------------------------------------------------------------+
|
|
| 7 | Bob | Bob retrieves the original message from Enrico and MessageKit |

Install NuCypher
|
|
----------------
|
|
|
|
Acquire the ``nucypher`` application code and install the dependencies.
|
|
For a full installation guide see the :doc:`/guides/installation_guide`.
|
|
|
|
Download the Book Text
|
|
----------------------
|
|
For your convenience we have provided a bash script to acquire the "Finnegan's Wake" text. However,
|
|
feel free to use any text of your choice, as long you you edit the demo code accordingly.
|
|
|
|
To run the script:
|
|
|
|
.. code::
|
|
|
|
(nucypher)$ ./download_finnegans_wake.sh
|
|
|
|
Run the Demo
|
|
---------------
|
|
|
|
After acquiring a text file to re-encrypt, execute the demo by running:
|
|
|
|
.. code::
|
|
|
|
(nucypher)$ python3 finnegans-wake-demo.py
|
