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