Thanks a lot for pointing out that possible licensing issue. It seems I'm not touching enough non-GPL code most days to keep that in the front of my mind :-) . > Is this code written by Andy Polyakov?

The git log for the original openssl ".pl" thankfully only contains @vrull.eu addresses, so getting this in a compatible license shouldn't be overly hard - I hope.
