Error-Detection-used-in-Computer-Communications-for-Data-Link-Layer-Security:

One way communication channel in which one or more threads can send message to a server. The message is encrypted using a specific encoding scheme and the CRC is calculated . The CRC is again calculated at the server side too, to check the authencity of the message.

The folder contains 2 files:

1. client.py
2. server.py

Multiple-clients can send message to the Server. The message will be sent to the server with encryption and the server will display the message.

To run the server file:

• python3 server.py

To run the client file:

• python3 client.py

Modules to be installed before running above files:

• pip3 install crccheck - For computing the crc on input message

Assumptions:

• Input Message should not contain spaces at the end.
