These are sample files to try out how the RSA and AES encryptions work.
The recommended usage of this is to use your own loopback IP (127.0.0.1) in two
terminal windows (so you can see in I/O of the server and client).
In addition, the serverPublicKey is the *actual* public key used in the lab, so
you'll want to use that in the actual attack.
File | Description |
-----------------+------------------------------------------------------------+
aes.py | Very basic classes for interfacing with AES and RSA |
rsa.py | methods |
-----------------+------------------------------------------------------------+
key.pub | A sample public key |
-----------------+------------------------------------------------------------+
key | A sample private key |
-----------------+------------------------------------------------------------+
sample_client.py | A client that encrypts the AES key and the word "True" and |
| sends it to the server |
-----------------+------------------------------------------------------------+
sample_server.py | A server that listens for messages from the client, |
| decrypts the client's message, capitalizes the plaintext, |
| and returns an encrypted version |
-----------------+------------------------------------------------------------+
serverPublicKey | The public key used by the true server for the lab |

README.txt | ...umm, this should be pretty self-explanatory, right? |

The python files should be run using python3, and you may need to install some
python packages depending on your environment (I'm not sure what they are, as
all the dependencies were present in my environments).
You can run the programs in the following way from the terminal:
$ python sample_server.py -p 10047 -kp key.pub -ks key
$ python sample_client.py -ip 127.0.0.1 -p 10047 -f key.pub
The first call stands up the server that listens on the specified port (10047
in this example). The -kp flag is the public key you'd like the server to use,
and -ks is the private key.
The second call kicks off a client on the loopback at the same port with -f
specifying the shared public key of the server.
