Virtual Private Networks (VPNs), which were first introduced to the market about two decades ago, have proven to be an enduring cornerstone of modern security. Most of the big shot businesses today use a VPN to provide private remote access, and millions of people use various VPN encryption types. These types are also available for free on many platforms. It helps protect their internet privacy, secure public Wi-Fi connections, and bypass site bans.
Most of us are aware that VPN tunnel encryption changes our IP address and routes our online traffic over an encrypted tunnel. However, not all virtual private networks (VPNs) are made equal. A VPN’s speed, capabilities, and even vulnerabilities may vary depending on the protocol used.
VPN technology relies on , techniques, and cyphers to determine how your “safe tunnel” is created. Each one offers a unique approach to the problem of browsing in a secure, private, and somewhat anonymous manner.
Though many of us are familiar with how a VPN works in general, due to the sheer complexity of the subject, it’s easy to become lost in the finer points of the technology. The fact that many are sloppy to the point of being misleading when explaining the type of encryption, they utilize adds to the confusion.
This article aims to serve as a quick reference for people interested in learning more about the technology that powers their VPN service. We’ll go over the various types of encryption, as well as the most used VPN protocols and the cyphers that go with them.
What is Encryption and its Advantages?
Is VPN encrypted? Yes! A VPN encryption technology adds an additional layer of security to your online experience. Data is encrypted so that only your VPN client and server can read it once they are securely connected. Data can be encrypted using a variety of security mechanisms. OpenVPN and IPSec are by far the most popular (this stands for Internet Protocol Security).
What is VPN encryption tunnel? Well, A VPN tunnel is a secure connection between your computer or mobile device and the internet. A VPN encryption tunnel connects your smartphone, laptop, computer, or tablet to a different network, masking your and encrypting all of the data you generate while browsing the web.
Are all VPNs encrypted? Well, VPNs are always encrypted. And, if you ever come across one that is not an encrypted VPN, it is not a VPN to begin with!
Now, if you are wondering what is encryption used for? Well, below we’ve mentioned a few of the advantages of using encryption that will help you understand its uses;
It Protects Your Data: “I don’t have any data worth stealing,” is the most typical justification against implementing proper cybersecurity policies. This assertion is false, as cybercriminals frequently target individuals in order to steal personal information.
When it comes to personal data, you might think of credit card and banking information, which is typically entered into the browser rather than saved on the machine. Other than credit card and banking information a lot of other forms of personal data can be infiltrated which is why encryption can be of good use.
Encryption prevents Identity Theft and Ransomware Blackmail: The most recent ransomware trend is to steal all of your data and then blackmail you into paying a ransom. If you don’t pay, your information will be released online, used for identity theft, or sold to the highest bidder. That’s terrifying!
The good news is that if your files are encrypted, thieves will not be able to access your information; instead, they will only be able to see scrambled data that is meaningless and cannot be held to ransom. Hence you can have a free trial of various VPN encryptions from VeePN.
What are the Features of Encryption?
Encryption, at its most basic level, entails replacing letters and numbers with numbers to encode data so that only authorized entities can access and interpret it. Encryption and decryption are currently performed using complex algorithms known as cyphers. These cyphers essentially signify a set of well-defined steps that can be repeated over and over again.
The operation of a cypher is frequently dependent on a piece of supplementary information known as a key; without the key, decrypting the resulting data is exceedingly difficult, if not impossible. Today, when we talk about encryption, we usually mean a combination of cypher and key-length, which refers to the number of ‘bits’ in a given key.
for example, the Blowfish-128, is the Blowfish cypher with a 128-bit key length. In general, a small key length indicates poor security because it is more vulnerable to brute-force attacks. The current ‘gold standard’ is a key length of 256 bits. This cannot be brute-forced because running through all possible bit combinations would take billions of years.
Symmetric-key
This occurs when the encryption and decryption keys are the same, and both communicating parties need to have the same key to communicate. This is the encryption method utilized by VPN providers.
Public-Key
To produce sets of public and private keys, the software is utilized. The public key is used to encrypt data before sending it to the private key owner. They then decrypt the messages using this private key.
Handshake encryption (RSA)
The usage of public-key encryption via a TLS handshake is required to securely connect to a VPN server. This handshake secures your connection, while a cypher safeguards your data.
Secure Hash Algorithm (SHA)
Data and SSL/TLS connections are authenticated using the Secure Hash Algorithm (SHA). A unique fingerprint is established throughout this process to – that is, to ensure you’re connected to the correct server. A hacker could reroute your traffic to their own server instead of your VPN provider’s if you don’t do this.
Because AES-256 encryption, OpenVPN, IKEv2, and SmartVeePN protocols create one of the most secure networks available, we chose them. SmartVeePN is a custom protocol of VeePN company. Smart VeePN, helps you smoothly surpass any geo-restrictions and conceals your traffic. The United States government utilizes the same ones for high-level communication, which says a lot.
