| 29 | * A secret (symmetric) key. |

| 31 | * <p>This interface contains no methods or constants. |
| 32 | * Its only purpose is to group (and provide type safety for) secret keys. |
| 33 | * |
| 34 | * <p>Provider implementations of this interface must overwrite the |
| 35 | * <code>equals</code> and <code>hashCode</code> methods inherited from |
| 36 | * <code>java.lang.Object</code>, so that secret keys are compared based on |
| 37 | * their underlying key material and not based on reference. |
| 38 | * |
| 39 | * <p>Keys that implement this interface return the string <code>RAW</code> |
| 40 | * as their encoding format (see <code>getFormat</code>), and return the |
| 41 | * raw key bytes as the result of a <code>getEncoded</code> method call. (The |
| 42 | * <code>getFormat</code> and <code>getEncoded</code> methods are inherited |
| 43 | * from the <code>java.security.Key</code> parent interface.) |
