Examples of javax.crypto.KeyAgreement.doPhase()

javax.crypto.KeyAgreement.doPhase()
Does the next (or the last) phase of the key agreement, using the specified key. @param key the key received from the other party for this phase. @param lastPhase set to {@code true} if this is the last phase of this keyagreement. @return the intermediate key from this phase or {@code null} if there isno intermediate key for this phase. @throws InvalidKeyException if the specified key cannot be used in this key agreement or this phase, @throws IllegalStateException if this instance has not been initialized.
