If the key is stored on a hardware device, its * specification may contain information that helps identify the key on the * device. * *
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
* x
, p
, q
, and g
* (see {@link DSAPrivateKeySpec}), or it may be
* specified using its DER encoding
* (see {@link PKCS8EncodedKeySpec}).
