Provides classes and interfaces for key specifications and
algorithm parameter specifications.

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.

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.
