Encryption could be at different layers.

It could be at the application layer where you have a tool with
encryption built in.

It could be file encryption where you could you a tool like PGP or
AXCrypt to encrypt one file at the time.

It could be at the session level where SSL or TLS could be used to
protect the whole session.

It could be at the network layer where IPSEC could be use to encrypt
the traffic.

It could be at the Data Links layer where many of the non IPSEC
tunneling tools would be located.

So to make a long story short: it can be use in many places

Take care
