Thanks, Alex.

I wouldn't worry much about security, this is as solid (or as weak) as

of minor leaks that will be addressed in time.

BR,
Nikos

Hi Nikos,

sorry for delay, patch commited to branch and after testing will be merged 
to trunk.

This branch can be found at: 
https://svn.kannel.org/gateway/branches/wtls_provision

I would like to see more people that can test/review this patch.

Thanks,
Alexander Malysh
