engineDoPhase	back to summary
protected Key engineDoPhase(Key key, boolean lastPhase) throws InvalidKeyException, IllegalStateException Implements abstract javax.crypto.KeyAgreementSpi.engineDoPhase. 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.

protected Key engineDoPhase(Key key, boolean lastPhase) throws InvalidKeyException, IllegalStateException

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
