<p><code>Bouncy Castle</code> is a Java library that complements the default Java Cryptographic Extension (JCE),
and it provides more cipher suites and algorithms than the default JCE provided by Sun.</p>
<p>In addition to that, <code>Bouncy Castle</code> has lots of utilities for reading arcane formats like PEM and ASN.1 that no sane person would want to rewrite themselves.</p>
<p>In Pulsar, security and crypto have dependencies on BouncyCastle Jars. For the detailed installing and configuring Bouncy Castle FIPS, see <a href="https://www.bouncycastle.org/documentation.html">BC FIPS Documentation</a>, especially the <strong>User Guides</strong> and <strong>Security Policy</strong> PDFs.</p>
<p><code>Bouncy Castle</code> provides both <a href="https://www.bouncycastle.org/fips_faq.html">FIPS</a> and non-FIPS version. But in a JVM, you can not include both of the 2 versions, and you need to exclude the current version before include the other.</p>
<p>In Pulsar, the security and crypto methods also depends on <code>Bouncy Castle</code>, especially in <a href="/docs/en/2.7.1/security-tls-authentication">TLS Authentication</a> and <a href="/docs/en/2.7.1/security-encryption">Transport Encryption</a>. This document contains the configuration between BouncyCastle FIPS(BC-FIPS) and non-FIPS(BC-non-FIPS) version while using Pulsar.</p>

<p>In Pulsar's <code>bouncy-castle</code> module, We provide 2 sub modules: <code>bouncy-castle-bc</code>(for non-FIPS version) and <code>bouncy-castle-bcfips</code>(for FIPS version), to package BC jars together to make the include and exclude of <code>Bouncy Castle</code> easier.</p>
<p>To achieve this goal, we will need to package several <code>bouncy-castle</code> jars together into <code>bouncy-castle-bc</code> or <code>bouncy-castle-bcfips</code> jar.
Each of the original bouncy-castle jar is related with security, so BouncyCastle dutifully supplies signed of each JAR.
But when we do the re-package, Maven shade explodes the BouncyCastle jar file which puts the signatures into META-INF,
these signatures aren't valid for this new, uber-jar (signatures are only for the original BC jar).
Usually, You will meet error like <code>java.lang.SecurityException: Invalid signature file digest for Manifest main attributes</code>.</p>
<p>You could exclude these signatures in mvn pom file to avoid above error, by</p>
<pre><code class="hljs css language-access transformers"><span class="hljs-tag">&lt;<span class="hljs-name">exclude</span>&gt;</span>META-INF/*.SF<span class="hljs-tag">&lt;/<span class="hljs-name">exclude</span>&gt;</span>
<span class="hljs-tag">&lt;<span class="hljs-name">exclude</span>&gt;</span>META-INF/*.DSA<span class="hljs-tag">&lt;/<span class="hljs-name">exclude</span>&gt;</span>
<span class="hljs-tag">&lt;<span class="hljs-name">exclude</span>&gt;</span>META-INF/*.RSA<span class="hljs-tag">&lt;/<span class="hljs-name">exclude</span>&gt;</span>
</code></pre>
<p>But it can also lead to new, cryptic errors, e.g. <code>java.security.NoSuchAlgorithmException: PBEWithSHA256And256BitAES-CBC-BC SecretKeyFactory not available</code>
By explicitly specifying where to find the algorithm like this: <code>SecretKeyFactory.getInstance(&quot;PBEWithSHA256And256BitAES-CBC-BC&quot;,&quot;BC&quot;)</code>
It will get the real error: <code>java.security.NoSuchProviderException: JCE cannot authenticate the provider BC</code></p>
<p>So, we used a <a href="https://github.com/nthuemmel/executable-packer-maven-plugin">executable packer plugin</a> that uses a jar-in-jar approach to preserve the BouncyCastle signature in a single, executable jar.</p>

<p>For Pulsar client, user need the bouncy-castle module, so <code>pulsar-client-original</code> will include the <code>bouncy-castle-bc</code> module, and have <code>&lt;classifier&gt;pkg&lt;/classifier&gt;</code> set to reference the <code>jar-in-jar</code> package.
It is included as following example:</p>
<pre><code class="hljs css language-xml">  <span class="hljs-tag">&lt;<span class="hljs-name">dependency</span>&gt;</span>

<p>By default <code>bouncy-castle-bc</code> already included in <code>pulsar-client-original</code>, And <code>pulsar-client-original</code> has been included in a lot of other modules like <code>pulsar-client-admin</code>, <code>pulsar-broker</code>.<br>
But for the above shaded jar and signatures reason, we should not package Pulsar's <code>bouncy-castle</code> module into <code>pulsar-client-all</code> other shaded modules directly, such as <code>pulsar-client-shaded</code>, <code>pulsar-client-admin-shaded</code> and <code>pulsar-broker-shaded</code>.
So in the shaded modules, we will exclude the <code>bouncy-castle</code> modules.</p>
