[Click] Problem with IPsecDES

[Marco Wenzel]

Hi Dimitris,

thanks for this explicitly explanation. After reading some more 
documents about IPSec and playing around with the Click-IPSec elements, 
I decided, that IPSec is not a suitable encryption-technique for my project.
I think SSL/TLS is a better solution for me. Did anyone implement Click 
elements, which can realize a SSL/TLS connection? After searching in the 
CVS and the official releases with the additional packages, I did not 
find any.

Best regards,
Marco.
