  27  * Provides classes and interfaces for key specifications and

  30  * <p>A key specification is a transparent representation of the key
  31  * material that constitutes a key. A key may be specified in an
  32  * algorithm-specific way, or in an algorithm-independent encoding
  33  * format (such as ASN.1).  This package contains key specifications
  34  * for Diffie-Hellman public and private keys, as well as key
  35  * specifications for DES, Triple DES, and PBE secret keys.
  36  *
  37  * <p>An algorithm parameter specification is a transparent
  38  * representation of the sets of parameters used with an
  39  * algorithm. This package contains algorithm parameter specifications
  40  * for parameters used with the Diffie-Hellman, DES, Triple DES, PBE,
  41  * RC2 and RC5 algorithms.
