/**
|
|
* 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 p}, {@code q}, and {@code g}
|
|
* (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.
