/**
* 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.
