The most important concepts are firewalls, authentication, encryption, and tunneling.When they receive it, they’ll decrypt it using your public key and their private key.Depending on the software, public and private keys can be large—too large for anyone to remember.Here we will give them a cursory rundown, then go into more detail in Chapter 2.An Internet firewall serves the same purpose as firewalls in buildings and cars: to protect a certain area from the spread of fire and a potentially catastrophic explosion.

Encryption is often considered as essential as authentication, for it protects the transported data from packet sniffing.There are two popular encryption techniques employed in VPNs: secret (or private) key encryption and public key encryption.Therefore, they’re often stored on the machine of the person using the encryption scheme.Because of this, private keys are typically stored using a secret key encryption method, such as DES, and a password or passphrase you can remember, so that even if someone gets on your system, they won’t be able to see what your private key looks like.In secret key encryption, there is a shared secret password or passphrase known to all parties that need access to the encrypted information.This single key is used to both encrypt and decrypt the information.Authentication can also be used to ensure data integrity.
