TCP server implemented in Python 🐍 that hosts files for a client to download them. The client can be found in the following repository: https://github.com/juanesmendez/tcp-client. The integrity of the files received by the client is guaranteed using a hash digest, which is calculated by the server and then sent to the client for him to compare it against the one he calculates on the byte stream he receives.
The following python libraries and classes were used in the server application:
socketpickle🥒: For serializing objects containing chunks of bytes and headers with important information for the client to check.hashlib🔑#️⃣: For calculating the hash digest of the file that is transferred to the client.select: For handling multiple users at once.
The files available for the client to download are located in the /files directory. Please follow the steps below to run the project successfully:
- Install
Python 3.7. - Run
python3.7 server.py- Your server will now be listening to TCP connections in the
port1236.
- Your server will now be listening to TCP connections in the
NOTE: You can change the port number in line #8 in the client.py file, but please keep in mind that you will have to change the port number as well in the client application in order to establish a connection with the server.
