public interface SecretKey extends Key
This interface contains no methods or constants. Its only purpose is to group (and provide type safety for) secret keys.
Provider implementations of this interface must overwrite the
hashCode methods inherited from
java.lang.Object, so that secret keys are compared based on
their underlying key material and not based on reference.
Keys that implement this interface return the string
as their encoding format (see
getFormat), and return the
raw key bytes as the result of a
getEncoded method call. (The
getEncoded methods are inherited
java.security.Key parent interface.)
