Hi Neil,

WTLS is a protocol that stays below WSP when used, but the WSP is encripted and almost impossible to decode unless a private key if fed into ethereal. What I needed was a way to decode the WTLS key transaction to confirm and see what messages was exchanged by the phone and WAP gateway.

I have a very new TDMA WAP phone so i see some different headers. I did not test connection-oriented mode just because all the phones that I have work in connection-less mode. I just received a new one that uses connection-oriented so in a few days I will probably send more patches. If you want to test any code just send it to me, I have tons of WTLS and WSP connections using diferent headers.

Are you doing some code to decode the WSP (WML data) part?. I will probably have to do that but it will take some time.

Thanks Neil,

And here it is!
Alexandre: thanks! The header decoding is getting fleshed out nicely now and
you've added support for some possibilities I hadn't seen before and therefore
assumed didn't occur (<4 byte date/time values). You've also fixed the
deliberate mistakes I left in to see if anyone was paying
attention... ahem... :)

I still can't help feeling that this is in slightly the wrong place - and may
not work in connection-oriented mode. I'll do a little more on this later on
today.

Cheers,
  Neil
