+Provides classes for implementing XML Encryption applications. There are two
+main families of classes in this package. The first group of classes is an
+XML Schema to Java mapping of the complex types and elements of the
+XML Encryption Schema as outllined at <a
+ href="http://www.w3.org/Encryption/2001/Drafts/xmlenc-core/">XML Encrtypyion
+Specification</a>. The second group of classes are used to perform encryption
+operations, and to manipulate the first group of classes. The most important
+classes in this second group is <code><a
+ href="file://./com/sun/org/apache/xml/internal/security/encryption/XMLCipher.html">XMLCipher</a></code>,
+<code><a
+ href="file://./com/sun/org/apache/xml/internal/security/encryption/XMLEncryptionFactory.html">XMLEncryptionFactory</a></code>
+and <code>XMLSerializer</code>. <code>XMLCipher</code> was designed to resemble
+<code>javax.crypto.Cipher</code>. The aforementioned classes were desinged
+with ease-of-use and configurability in mind. Becuase of this, the programmer
+may at times be exposed to lower level programming tasks. This library strives
+to be as simple as possible to use, but no simpler.<br>
