| <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/next/security-tls-authentication">TLS Authentication</a> and <a href="/docs/en/next/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> |

| <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("PBEWithSHA256And256BitAES-CBC-BC","BC")</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> |
