The cryptographic operations defined in this package include encryption, key generation and key agreement, and Message Authentication Code (MAC) generation. <p>Support for encryption includes symmetric, asymmetric, block, and stream ciphers. This package also supports secure streams and sealed objects. <p>Many of the classes provided in this package are provider-based. The class itself defines a programming interface to which applications may write. The implementations themselves may then be written by independent third-party vendors and plugged in seamlessly as needed. Therefore application developers may take advantage of any number of provider-based implementations without having to add or rewrite code. <h2>Package Specification</h2> <ul> <li><a href="https://docs.oracle.com/javase/8/docs/technotes/guides/security/StandardNames.html"><b> <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= "https://docs.oracle.com/javase/8/docs/technotes/guides/security/crypto/CryptoSpec.html"> <b>Java<FONT SIZE=-2><SUP>TM</SUP></FONT> Cryptography Architecture (JCA) Reference Guide </b></a></li> <li> <a href= "https://docs.oracle.com/javase/8/docs/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> </ul> @since 1.4 </body> </html>
