  31 Provides interfaces for Diffie-Hellman keys as defined in
  32 RSA Laboratories' PKCS #3.
  33 <P>
  34 Note that these interfaces are intended only
  35 for key implementations whose key material
  36 is accessible and available. These
  37 interfaces are not intended for key
  38 implementations whose key material resides
  39 in inaccessible, protected storage (such as
  40 in a hardware device).
  41 <P>
  42 For more developer information on how to use
  43 these interfaces, including information on
  44 how to design <code>Key</code> classes
  45 for hardware devices, please refer to the
  46 cryptographic provider developer guide:
