Put the jar file in

<DAISY_HOME>/lib/bouncycaste/jars/bouncycastle-<version>.jar

(The lib dir is a Maven-style repository, in case you would be familiar
with that.)

Then create a classloader.xml like:

<classloader>
  <classpath>
    <artifact groupId="bouncycastle" artifactId="bouncycastle" version="the version number"/>
  </classpath>
</classloader>

Rebuild the plugin so that the classloader.xml is in the plugin jar, and
that should be all.

It is currently not very nice that the jar needs to be added to the
<DAISY_HOME>/lib dir, there's already a jira issue [1] which covers
this.
