4. What is VPN ?
• When you connect to the internet
with a VPN, it creates a connection
between you and the internet that
surrounds your internet data like a
tunnel, encrypting the data packets
your device sends.
• The tunnel is created by
encapsulating the data packets
within another packet and sending
them through the internet to the
VPN server . The VPN server then
decrypts the data packets and
forwards them to their intended
destination.
• A Virtual Private Network
(VPN) is a technology that creates
a secure and encrypted connection
over a less secure network, such
as the Internet . VPNs are used to
protect your online privacy and
security by masking your IP
address and encrypting your
internet traffic.
• VPN tunneling is a technique
used by Virtual Private Network
(VPN) services to create a secure
and encrypted connection between
your device and the internet.

6. What coding language was used ?
Python
Python is an interpreted, object-oriented, high-level
programming language with dynamic semantics. Its high-
level built in data structures, combined with dynamic typing
and dynamic binding, make it very attractive for Rapid
Application Development, as well as for use as a scripting
or glue language to connect existing components together.

8. MAKING PROCESS
• This code snippet demonstrates how to create a VPN
server using the OpenSSL and socket libraries
1
.
• The code defines a function handle_client that receives
data from a client socket and adds VPN-like logic to
it
1
. The function start_vpn_server creates a socket
object, binds it to a specified IP address and port
number, and listens for incoming connections
1
.
• When a client connects to the server,
the handle_client function is called to handle the
connection
1
.
• The if __name__ == '__main__': block at the end of the
code ensures that the start_vpn_server function is only
called when the script is run directly, and not when it is
imported as a module
1
.

10. GUI
• Python offers multiple options for
developing GUI (Graphical User
Interface).
• Out of all the GUI methods,
tkinter is the most commonly
used method.
• It is a standard Python interface
to the Tk GUI toolkit shipped with
Python.
• Python tkinter is the fastest and
easiest way to create GUI
applications. Creating a GUI
using tkinter is an easy task.
