Why is it Necessary to Use a VPN?

Computers and Technology How to

VPN is a Virtual Private Network that helps you to keep your browsing private and safe from cybercriminals. These hackers can steal your confidential information and misuse it. These cybercriminals can use your banking credentials and/or confidential information that can ruin your entire business’ credibility. Getting a VPN connection will relieve you from worrying about your confidential information since it converts the data into encrypted form.

How Does a VPN Work? 

The main purpose of a Circuit VPN is to hide your original IP address and change it by configuring the remote server with an anonymous IP address. When you are surfing the internet with a VPN, it becomes the source of conversion of your data. It converts your data into gibberish which is unreadable for hackers.

It helps in converting your internet connection into a private server connection that converts your data into unreadable form. The unreadable form of data remains gibberish until it has been sent to the receiver. VPN creates a secure tunnel with your server and the device which hides your data, and this process is known as encryption. 

How Does Encryption Work? 

Encryption of data is the procedure that converts your information into an unreadable form. This makes sure that your data remains hidden until it is sent to the receiver. It can be a text, message, or email. When the information has been sent to the receiver, it converts to its original form which is known as decryption. The user and the receiver have a secret encryption key that helps in the conversion of data. These keys are very essential for decrypting the data and see the original text.

If you share personal data or confidential information about your business, you need not worry about the information being hacked by cybercriminals or those who want to ruin your reputation in the marketplace. 

Types of Encryption 

There are different types of encryption that help in securing your information. Each of the following has advanced features designed for different purposes. 

  • Triple DES (Data Encryption Standard) 

Triple DES or Triple Data Encryption Algorithm runs a strong DES connection triple time. It encrypts, decrypts, and re-encrypts the data. And the decryption of data involves decryption, encryption, and re-decryption. It is supported by the symmetrical encryption of data which made DES a weaker connection in securing data. 

  • Data Encryption Standard (DES)  

Data Encryption Standard is the lowest encryption standard. It is created by the US government in 1977. However, this type of encryption has been obsoleted from the market. 

  • RSA (Rivest-Shamir-Adleman) 

RSA encryption involves two main keys for the encryption of data: 

  • The public key for encryption 
  • The private key for decryption 

It is considered the best encryption algorithm. The larger the algorithm key will be, the slower the encryption process is. 

  • AES (Advanced Encryption Standard) 

The Advanced Encryption Standard (AES) works on a single private key that ensures the best security of your data. It was developed by the US National Institute of Standards and Technology. It involves different rounds of encryption to secure your data. 

  • TwoFish 

This type of encryption is the fastest type of encryption and has the most advanced features for the protection of your data. It involves 16 rounds of encryption for your data and is called the most flexible type of encryption. The encryption process is quick; however, the key setup is slow.

  • Blow Fish 

This encryption algorithm works on a variable key that divides the data into two forms; encryption and decryption. It is fast and free public encryption software. It has been tested for its speed, security, and efficiency. This encryption process is great for securing data like transactions, payments, passwords, and other sensitive information.

  • FPE (Format Preserving Encryption) 

This type of encryption is used in financial database systems, banking systems, etc. It encrypts your data in the same format. 


All of the above-stated information concludes that VPNs ensure the best security for your data. You can connect to public Wi-Fi without having to worry about your sensitive data being hacked by cybercriminals that can misuse your information. You can freely log into your bank account, share confidential emails that have sensitive information about your business, or a new business idea that can bring an innovative change to your business.
