This
class is a transparent and algorithm-independent representation of a
secret key. This class is useful only for encryption algorithms (such
as DES and DESede) whose secret keys can be represented as arbitrary
byte arrays and do not require auxiliary parameters. Note that
SecretKeySpec implements the
javax.crypto.SecretKey interface directly, so no
algorithm-specific javax.crypto.SecretKeyFactory
object is required.
