| KeyAgreementSpi | javax.crypto |
This abstract class defines the
service-provider interface for KeyAgreement. A
cryptographic provider must implement a concrete subclass of this
class for each encryption algorithm it supports. Applications never
need to use or subclass this class.public abstract class KeyAgreementSpi {
