+<h2><a name="Serializing_and_De-serializing_Cache_Objects"></a>Serializing and De-serializing Cache Objects</h2>
+
+<p> When using auxiliary caches, cache elements need to be serialized
+ into a byte stream in order to be stored on disk or transported
+ through a network. For reading from these caches, bytes must be
+ de-serialized into objects. By default, JCS uses the standard JDK
+ methods for serializing and de-serializing objects. However, all
+ of the auxiliaries also support setting a custom serializer to
+ have finer control of the behavior.</p>
+
+
+<p> This document describes the built-in serializers and their
+ configuration.</p>
+ </section>
+ <section>
+<h2><a name="Compressing_Serializer"></a>Compressing Serializer</h2>
+
+<p> The <code>CompressingSerializer</code> gzips the bytes
+ after serializing the cache object the default way. For reading,
+ the bytes will be de-compressed first and then de-serialized into
+ a Java object. The class can also be used as a wrapper around an
+ arbitrary class implementing <code>IElementSerializer</code>.</p>
+
+
+<p> The configuration for a typical application looks like this:</p>
+
+<div class="source">
+<pre>
+
+# Block Disk Cache
+jcs.auxiliary.blockDiskCache=org.apache.commons.jcs3.auxiliary.disk.block.BlockDiskCacheFactory
+jcs.auxiliary.blockDiskCache.attributes=org.apache.commons.jcs3.auxiliary.disk.block.BlockDiskCacheAttributes
+jcs.auxiliary.blockDiskCache.attributes.DiskPath=target/test-sandbox/block-disk-cache
+jcs.auxiliary.blockDiskCache.serializer=org.apache.commons.jcs3.utils.serialization.CompressingSerializer
+
+ </pre></div>
+ </section>
+ <section>
+<h2><a name="Encrypting_Serializer"></a>Encrypting Serializer</h2>
+
+<p> The <code>EncryptingSerializer</code> uses AES to encrypt the bytes
+ after serializing the cache object the default way. For reading,
+ the bytes will be decrypted first and then de-serialized into
+ a Java object. The class can also be used as a wrapper around an
+ arbitrary class implementing <code>IElementSerializer</code>.</p>
+
+
+<p> The implementation uses a symmetrical pre-shared key phrase for
+ encrypting and decrypting the data. The key is salted separately
+ for each object and the salt is stored together with the serialized
+ data.</p>
+
+
+<p> The configuration for a typical application looks like this:</p>
+
+<div class="source">
+<pre>
+
+# Block Disk Cache
+jcs.auxiliary.blockDiskCache2=org.apache.commons.jcs3.auxiliary.disk.block.BlockDiskCacheFactory
+jcs.auxiliary.blockDiskCache2.attributes=org.apache.commons.jcs3.auxiliary.disk.block.BlockDiskCacheAttributes
+jcs.auxiliary.blockDiskCache2.attributes.DiskPath=target/test-sandbox/block-disk-cache2
+jcs.auxiliary.blockDiskCache2.serializer=org.apache.commons.jcs3.utils.serialization.EncryptingSerializer
+jcs.auxiliary.blockDiskCache2.serializer.attributes.preSharedKey=my_secret
+
+ </pre></div>
+
+
+<p> The AES cipher transformation default is AES/ECB/PKCS5Padding as this
+ algorithm must be supported by every JDK 8, according to the
+ <a class="externalLink" href="https://docs.oracle.com/javase/8/docs/api/javax/crypto/Cipher.html">docs</a>.
+ Special handling is provided for the AES/GCM/NoPadding algorithm which
+ can be activated like this:</p>
+
+<div class="source">
+<pre>
+
+jcs.auxiliary.blockDiskCache2.serializer.attributes.aesCipherTransformation=AES/GCM/NoPadding
+
+ </pre></div>
+
+
+<p> The encryption code uses the default constructor of SecureRandom() to create
+ a random number generator. Depending on your security requirements, you should
+ configure a SecureRandom that works for your environment, giving preference to
+ the ones with good randomness (given that your environment generates entropy fast
+ enough, we saw problems with Linux).</p>
