Release is based on https://github.com/RealMalWare/openhab-addons/tree/E3DC
Adjustments I did were rather small (will later push them to my repository whenever I have time: changed pom.xml to latest bouncycastle release https://www.bouncycastle.org/latest_releases.html (libs could be downloaded there, included the pom.xml in case someone want to keep working), updated header of files).
The Jar should include all you need
