Finally,this package provides classes that support signed/guarded objectsand secure random number generation. Many of the classes provided in this package (the cryptographicand secure random number generator classes in particular) areprovider-based.  The class itself defines a programming interfaceto which applications may write.  The implementations themselves maythen be written by independent third-party vendors and pluggedin seamlessly as needed.  Therefore application developers maytake advantage of any number of provider-based implementationswithout having to add or rewrite code. <h2>Package Specification</h2> <ul>  <li><a href="{@docRoot}/../technotes/guides/security/crypto/CryptoSpec.html">    <b>Java<FONT SIZE=-2><SUP>TM</SUP></FONT>    Cryptography Architecture (JCA) Reference Guide</b></a></li>   <li>PKCS #8: Private-Key Information Syntax Standard, Version 1.2,    November 1993</li>   <li><a href="{@docRoot}/../technotes/guides/security/StandardNames.html">    <b>Java<FONT SIZE=-2><SUP>TM</SUP></FONT>    Cryptography Architecture Standard Algorithm Name     Documentation</b></a></li></ul> <h2>Related Documentation</h2> For further documentation, please see:<ul>  <li><a href=    "{@docRoot}/../technotes/guides/security/spec/security-spec.doc.html">    <b>Java<FONT SIZE=-2><SUP>TM</SUP></FONT>    SE Platform Security Architecture</b></a></li>   <li><a href=    "{@docRoot}/../technotes/guides/security/crypto/HowToImplAProvider.html">    <b>How to Implement a Provider in the    Java<FONT SIZE=-2><SUP>TM</SUP></FONT> Cryptography Architecture    </b></a></li>   <li><a href=    "{@docRoot}/../technotes/guides/security/PolicyFiles.html"><b>    Default Policy Implementation and Policy File Syntax    </b></a></li>   <li><a href=    "{@docRoot}/../technotes/guides/security/permissions.html"><b>    Permissions in the    Java<FONT SIZE=-2><SUP>TM</SUP></FONT> SE Development Kit (JDK)    </b></a></li>   <li><a href=    "{@docRoot}/../technotes/guides/security/SecurityToolsSummary.html"><b>    Summary of Tools for    Java<FONT SIZE=-2><SUP>TM</SUP></FONT> Platform Security    </b></a></li>   <li><b>keytool</b>    (<a href="{@docRoot}/../technotes/tools/solaris/keytool.html">      for Solaris/Linux</a>)    (<a href="{@docRoot}/../technotes/tools/windows/keytool.html">      for Windows</a>)    </li>   <li><b>jarsigner</b>    (<a href="{@docRoot}/../technotes/tools/solaris/jarsigner.html">      for Solaris/Linux</a>)    (<a href="{@docRoot}/../technotes/tools/windows/jarsigner.html">      for Windows</a>)    </li> </ul> @since 1.1</body></html>
