Name

Class javax.crypto.KeyAgreement

Synopsis

This engine class represents a key agreement protocol, which is an arrangement by which two parties can agree on a secret value. You can obtain an instance of this class by calling the getInstance() method. After initializing the object (see init()), you can step through the phases of the key agreement protocol using the doPhase() method. Once the phases are complete, the secret value (that is, the key) is returned from the generateSecret() method.
