A VPN uses encryption to protect data in transit. Any transmissions that are intercepted will be indecipherable without the proper encryption key.
Encryption is the process of transforming readable data into an unreadable format. This is done using an encryption algorithm and a key. The key is what encrypts and decrypts the data. Without the key, the data is unreadable.
A VPN uses a variety of encryption algorithms to protect data. This ensures that your data is safe from prying eyes, whether it be your ISP or anyone else who might be monitoring your traffic.
What Is Tunneling?
Tunneling is the process of encapsulating data in an outer layer of encryption before sending it over a network. This adds an extra level of security since the data is encrypted twice. When the data reaches its destination, the outer layer of encryption is removed and the data is decrypted.
What Is a VPN Tunnel?
A VPN tunnel is a secure, encrypted connection between two devices. Tunneling protocols are used to encrypt data before it is sent over the public network. This adds an extra level of security since the data is encrypted twice.
VPN tunnels are used to protect data in transit. All data that is sent over a VPN connection is encrypted using a tunneling protocol. The most common tunneling protocols are IPsec, SSL/TLS, and IKEv2.
