public abstract class DHCryptoToken
extends Object
implements AsymmetricCryptoToken

An interface for DH cryptographic tokens to implement.

Note: This class must be extended in order to override the default implementation.

Note: It is considered good practice to implement the equals and hashCode methods when extending this class. Otherwise, odd behaviour can occur.
