A VPN is a great tool to have for those who are looking to protect their privacy and maintain anonymity. But what should you look for when choosing a VPN? There are many features that determine the level of security a VPN offers, but encryption is one of the most important factors, especially for Windows users.
In this article, we will discuss encryption levels including AES-128 bit encryption and AES-256 bit encryption as well as different protocols such as OpenVPN, L2TP/IPSec, PPTP, and SSTP. This information should help you choose which encryption option best fits your needs!
AES-128 or AES-256 bit Encryption: Which is the Best for Windows
AES-128 bit encryption or bank-grade encryption. This is a common level of encryption for VPNs because it offers strong security without compromising on speed. It is less of a target for hackers since its key algorithms are slightly stronger which makes it perhaps a better option for some internet users.
AES-256 bit encryption is considered stronger against brute force attacks, which makes it a good option for VPN users looking to protect their data from hackers. This level of encryption is used by militaries and governments due to the strength it offers.
There are still some concerns about using 256-bit AES encryption standards however since there have been vulnerabilities reported by researchers who have tried cracking them after intercepting data while being transmitted over an IP network. But don’t let these reports scare you off from going with 256-bit AES standards; they haven’t yet discovered a practical attack against the algorithm itself.
Do Protocols Affect VPN Encryption?
Yes, VPN protocols are a major part of encryption. Without different protocols to encrypt your data while it travels over the Internet before it reaches its destination, you would not be able to connect or communicate with other users on private networks like business and corporate servers. There are many different options for VPN protocols including OpenVPN which is often considered one of the best due to its reliability in protecting information transmitted through online connections.
When you download a VPN for Windows, such as if you install the Cisco VPN client on Windows 10, you can often adjust the protocols to decide whether your VPN encryption is fast or more secure. Here are some of the most common encryption protocols:
OpenVPN: OpenVPN is a robust and reliable protocol that is often considered one of the best. The latest version offers AES-256 bit encryption which makes it a good option for those who prioritize security over speed.
WireGuard: WireGuard is a new VPN protocol that offers both speed and security. It is still in an experimental phase but it could provide some advancements on older standards, particularly with its use of state-of-the-art cryptography to secure the connection between two devices.
IPSec: IPSec has been around for a while, which means most Windows users are familiar with it. However, there are some concerns about IPSec security because its two sub-protocols have been known to be vulnerable in the past. If you decide on using IPSec encryption make sure that your VPN provider uses IKEv version one or higher since this protocol is now considered more secure than previous versions.
PPTP: PPTP is an older VPN protocol that has been known to be insecure. However, this encryption standard is still in use by some providers today since it does not require the high processing power of more advanced protocols like OpenVPN or IPSec. PPTP offers 128-bit encryption which makes it a good option for fast speeds but less secure than other options.
