This repository is the source documents for the NIS 2022 Practical. Implementing a client server communication protocol that implements end-to-end encryption using the BouncyCastlesFips library.
The following Java class files can be found under the src directory:
| Class | Description |
|---|---|
| Utils | Utils for running the client server setup. |
| KeyWithMessageDigest | A class for wrapping a signed one time key with a signed message digest. |
| Hashing | A class for testing the hashing and signing flow. |
| Encryption | A class for testing the encryption flow. |
| HashingAndEncryption | A class for testing the full flow including hashing, signing and encryption methods. |
| ClientHandler | This class helps the server keep track of all connected clients. |
| Client | This class represents the client in a client-server network. |
| ClientRunner | Creates a key pair for a Client then runs a new instance of a Client passing in the key pair encoded. |
| Server | This class represents the server in a client-server network. |
There is a Makefile in the root of the repository to make running the client-server network easy. In order to setup a network you can run the following commands in separate terminals:
make
make server
make client
make client
Javadocs can also be generated by running make docs. This will generate documentation in the doc directory. Opening the index.html file will open a webpage with documentation for all the classes in the repository.
Once the server is running, each new client will request a name. Once the name is granted, the client is connected and can send/receive messages from the group.
