sudo apt-get install openssl libssl-dev

Zlib (For Gzip compression/decompression)

sudo apt install zlib1g zlib1g-dev

SQLite3 (For storing user information)

sudo apt install sqlite3 libsqlite3-dev

build-essential (Required build tools)

sudo apt install build-essential 

Cmake (For building the project)

sudo apt install cmake

Generating SSL Certificate and Key for the Server

1. Navigate to the /security directory inside the server folder:

   cd server/security

2. Generate a self-signed SSL certificate and private key:

   openssl req -x509 -nodes -days 365 -newkey rsa:2048 \
   -keyout server.key -out server.crt -config openssl.cnf

3. Copy the generated certificate (server.crt) to the client’s /security directory:

   cp server.crt ../../client/security

Build Instructions

Build the Server

1. Navigate to the server directory:

   cd server

2. Create a build directory and compile:

   mkdir -p build
   cd build
   cmake ..
   cmake --build .

3. Run the server:

   sudo ./bin/server <server_portno>

   Example:

   sudo ./bin/server 8000

Build the Client

1. Navigate to the client directory:

   cd client

2. Create a build directory and compile:

   mkdir -p build
   cd build
   cmake ..
   cmake --build .

3. Run the client:

   ./bin/client <server_ipaddress> <server_portno>

   Example:

   ./bin/client 127.0.0.1 8000

Debugging with Valgrind

Valgrind can be used to check memory leaks and runtime errors.

Debugging the Server

sudo valgrind --leak-check=full --track-origins=yes ./bin/server <server_portno>

Debugging the Client

valgrind --leak-check=full --track-origins=yes ./bin/client <server_ipaddress> <server_portno>

---

Example Usage

Start the Server

sudo ./bin/server 8000

Start the Client

./bin/client 127.0.0.1 8000
