Java Cryptography

Name

Class javax.crypto.KeyAgreement

Description

This 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 getInstance(). Once the KeyAgreement is initialized (see init()), you can step through the phases of the key agreement protocol using doPhase(). Once the phases are complete, the secret value is returned from generateSecret().
