Proactive VPN Encryption and Protection Explained
VPN encryption is a complex process since it implements well-tested advanced mathematics procedures. Keep reading to understand how ExtremeVPN ensures your data and communications safety.
How Reliable is the Encryption of ExtremeVPN?
ExtremeVPN not only just hides your IP address from other users but also encrypts the traffic between your computer and secure VPN servers. This restricts third-party organizations from accessing your data.
Our VPN uses the AES-256 protocol – an Advanced Encryption Standard with 256-bit keys. This encryption standard is famous in the US, and many security professionals use it to protect their classified data.
256-bit keys refer to a possible combination of 1.1 x 10^77 or 2^256, which are 089,115,195,237,316,792,423,985,570,008,907,687,853,984,269,665,560,640,000,000,000,000,000,000,000,000 combinations! It means a brutal attack on 256-bit keyspace is virtually impossible, even if you can run the world’s strongest computers forever, for thousands of millions of years.
A Guide to VPN Protocols and Lightway
ExtremeVPN utilizes a number of VPN protocols to provide safe and secure encryption between your PC and the VPN servers. We allow users to switch between these protocols easily. However, a much better approach is to select the default setting, which automatically adjusts the most suitable protocol for your speed and security.
Besides providing some basic set of protocols, such as IKEv2 and OpenVPN, Lightway is a custom built protocol, which surpasses others in terms of reliability, security, and speed. It provides a more secure, more faster VPN experience.
What is VPN Tunneling and Encryption?
Like OpenVPN and HTTPS, Lightway uses certifications to protect you from monster-in-the-middle (MITM) attacks. Your VPN clients validate servers with these certificates. When using a free source or an external Lightway client, you can connect to VPN servers by loading these certificates.
The two ciphers used in Lightway are ChaCha20/Poly1305 and AES-256-GCM. As AES has exceptional hardware acceleration, it’s most likely that Lightway will use this well-recognized cipher by default. ChaCha20, in contrast, only works on lower-powered routers.
HMAC stands for Keyed-Hash Message Authentication Code. This code prevents hackers from making amendments to the data while streaming. OpenVPN and TLS rely on hashes for data authentication.
Encryption of Control Channels
Cipher AES-256-GCM is popular worldwide for its systematic encryption standards. ExtremeVPN uses it to ensure the privacy and integrity of encrypted data, even on low-powered hardware. The 256 explains that each encrypted block has a fixed size of 256 bits. GCM (Galois/Counter Mode) offers to encrypt multiple pieces of information simultaneously, ensuring that your connection never drops for a single minute.
Encryption of Data Channels
Data channel encryption hides your information from parties that can access it. ExtremeVPN applies a symmetric technique called elliptic curve Diffie-Hellman (ECDH) for selecting a special type of key. This key is used for encryption and decryption, protecting the data for the entire session. ExtremeVPN servers and your VPN app limit access only to authorized people.
