28/**
29 * A (transparent) specification of the key material
30 * that constitutes a cryptographic key.
31 *
32 * <p>If the key is stored on a hardware device, its
33 * specification may contain information that helps identify the key on the
34 * device.
35 *
36 * <P> A key may be specified in an algorithm-specific way, or in an
37 * algorithm-independent encoding format (such as ASN.1).
38 * For example, a DSA private key may be specified by its components
39 * {@code x}, {@code p}, {@code q}, and {@code g}
40 * (see {@link DSAPrivateKeySpec}), or it may be
41 * specified using its DER encoding
42 * (see {@link PKCS8EncodedKeySpec}).
43 *
44 * <P> This interface contains no methods or constants. Its only purpose
45 * is to group (and provide type safety for) all key specifications.
46 * All key specifications must implement this interface.
