Java Security, 2nd Edition

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.
