For some time now I was trying to setup KMail to work with GnuPG but I did always fail. I did RTFM, but apparently not close enough. After I did manage to get it working I did write down my experiences and like to share them with you. The result is a englisch Howto and an german Howto which try to explain how to setup KMail to use GnuPG. Have fun and notify me in case I made an mistake!
