/**
 * Provides classes and interfaces for key specifications and
 * algorithm parameter specifications.
 *
 * <p>A key specification is a transparent representation of the key
 * material that constitutes a key. A key may be specified in an
 * algorithm-specific way, or in an algorithm-independent encoding
 * format (such as ASN.1).  This package contains key specifications
 * for Diffie-Hellman public and private keys, as well as key
 * specifications for DES, Triple DES, and PBE secret keys.
 *
 * <p>An algorithm parameter specification is a transparent
 * representation of the sets of parameters used with an
 * algorithm. This package contains algorithm parameter specifications
 * for parameters used with the Diffie-Hellman, DES, Triple DES, PBE,
 * RC2 and RC5 algorithms.
