Detailed explanation-1: -A VPN uses tunneling protocols to encrypt data at the sending end and decrypts it at the receiving end. The originating and receiving network addresses are also encrypted to provide better security for online activities. VPN apps are often used to protect data transmissions on mobile devices.
Detailed explanation-2: -A VPN works by encrypting your online presence. The only way to decipher this encryption is with a key. Only your computer and the VPN know this key, making it impossible for your ISP to tell where you are browsing.
Detailed explanation-3: -VPNs use public-key encryption to protect the transfer of AES keys. The server uses the public key of the VPN client to encrypt the key and then sends it to the client. The client program on your computer than decrypts that message using its own private key.
Detailed explanation-4: -IPsec operates at the network layer and can be used to encrypt data being sent between any systems that can be identified by IP addresses.
