public abstract class ECCryptoToken
An interface for EC 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.
Details on implementing for smart cards.
