Answer: "An instance of a class"
Explanation:
When you create an object, you are creating an instance of a class, therefore "instantiating" a class.
You create an object from a class, thus you can say that a class provides the blueprint for objects.
When used in object-oriented programming, a class is a factory for creating objects and Such objects are called "instances" of the class.
DH is an algorithm to derive a shared secret over an unsafe channel.
Both parties exchange public keys, and can join them together with their private keys to create the secret. An eavesdropper can see both public keys, but since he doesn't posess the private keys, cannot derive the same secret.
The secret can be used to subsequently encrypt communications with a symmetric algorithm.
TLS uses this approach.
