Doc from javax.crypto.KeyAgreementSpi.engineDoPhase.

Executes the next phase of this key agreement with the given key that was received from one of the other parties involved in this key agreement.

Parameters
key:Key

the key for this phase. For example, in the case of Diffie-Hellman between 2 parties, this would be the other party's Diffie-Hellman public key.

lastPhase:boolean

flag which indicates whether this is the last phase of this key agreement.

Returns:Key

the (intermediate) key resulting from this phase, or null if this phase does not yield a key

Exceptions
InvalidKeyException:
if the given key is inappropriate for this phase.
IllegalStateException:
if this key agreement has not been initialized.
