AES-256 encryption
Total VPN states that it uses AES-256 encryption to protect traffic travelling through the VPN tunnel.
User benefit
Helps reduce the visibility of routed traffic to observers on the same local network.
Practical use case
A traveller connects before using hotel Wi-Fi to add an encrypted layer between the device and the VPN server.
Important limitation
Encryption does not protect traffic after it leaves the VPN server, and it does not make unsafe websites trustworthy.
