public abstract class PKCS11KeyAgreement
This is a generic base implementation for a key agreement. It serves as base class for concrete
implementations that use a PKCS#11 token to calculate the cryptographic operations. This
implementation must be initialized using a PKCS11KeyAgreementSpec. Other types of initialization
are unsupported. This is necessary, because this implemetation requires certain information for
PKCS#11 operations, which it cannot get by other means.
