Although nowadays people can easily look for the best VPN that functions and can be operated in a much simpler way, they can still make their own VPN connection by using Phyton. But, is it actually possible to do so?
Python is indeed an interesting programming language that’s versatile and highly functional for so many purposes. Creating a whole new VPN connection won’t be as easy as using the premium VPN services that are widely available on the market, but at least it’s still doable as long as you have the proper knowledge for it.
Let us first understand the basic of VPN.
Understanding the Basics of VPN
Now, before we start messing with the Phyton, let us first understand about the whole concept of a VPN. VPN stands for Virtual Private Network, and it’s used by all people around the world to make their internet connection more secure through the servers provided by the VPN providers.
Each user can safely and easily switch between locations with a very simple operation of clicking. You can be at the US, and one second later you can move on to Singapore.
Although there are some types of VPN you can find out there, the way they work is generally the same. These VPN services will make your internet connection safe and protect you from the danger of cybersecurity attack.
Now that you’ve finally understood about VPN, let us start building a VPN location using Phyton.
Building A Virtual Private Network In Python
1. Selecting The Protocol
The very first step you need to do is selecting the correct protocol. The protocol will determine who the data will be transmitted over the internet. In this case, you can use the populer ones onstead, like PPTP, IPSec, or OpenVPN.
Surely, each of them have their own plus and minus, but as an example, let’s stick with the popular ones that have more support than the others.
2. Setting Up the Server
Let’s say we use the OpenVPN as an example, which is one of the most commonly used protocols. So, how we can set up a VPN server using OpenVPN?
Generally, there are four main steps you need to do: installing the protocol, configuring the server, generating the certificates, and finally establishing a new connection.
3. Encryption Implementation
The VPN connection is generally encrypted, so no other parties could ever snoop into it. Encryption is basically the key for the VPN service to work so you better pay your outmost attention to it.
There are several types of encryption that can be used on this case, like the symmetric and asymmetric encryption.
4. VPN Server Authentication
After obtaining the account details from VPN providers, you can get the certifications, which play an important role to authenticate the servers. Before talking about the setup with ready VPNs you can choose shared or dedicated IP, let us explain to you about this verification methods.
In order to authenticate the server, you have to import the public keys to the client’s certificate and configure it. There are some elements you need to configure, such as the port number, the IP address, certificates, and the phone number. These information can be obtained from the VPN provider.
5. Do The Testing
Now that everything has been set up, you can finally do the testing. These testing require several process to do, like checking the errors found in the implemented codes, and troubleshooting the connection to find any technical errors within.
6. Enhancing The Security
If the internet connection is okay, you can also enhance the security by implementing the multi-factor authentication, SSL certificates, and more. And then, you can finally deploy the Phyton-based VPN by always monitor and manage its performance.
As the developer, you can also use regular updates to make it working properly.
Thoughts On Computer Security
In today’s modern age, computer security is surely an important aspect that you should need to focus on. You, as a user, can always enhance your computer security by performing the regular updates if necessary, using authentication, and making sure that any personal or sensitive information stored securely.
You can also do several things to keep you safe on the internet, like using the complex passwords for all your accounts. Although it seems tedious, you can always simplify it by using a password manager which functions to store all your passwords into one, secure location.
Make sure that any software on your computer is updated, especially the ones related to the operating system. Every update always brings the newer security improvements. So the more updated the system is, the better security you’ll have.
Also, be warry of phishing. Although we’ve been familiar with it for such a long time, phishing is still happening all around us. So, before clicking any links or websites given to you, always check its authenticity and legitimacy. Make sure that you don’t click any malicious and suspicious links.
