| 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>, <code>p</code>, <code>q</code>, and <code>g</code> |
| 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. |
