Hi Andreas,
I agree with Nikos there are phones out there that still use wtls.
Also what's the problem with including it with Kannel, then if developers
require it, they can use it.

Maybe, but kannel has never been a wap 2.0 gateway. Only a 1.x. Besides
there are still wap 1.x phones around that use wtls even today.

WSP and WTP are supported in Kannel
WTLS is a dead end. Its only used in WAP 1.1 while the world uses WAP 2.0
these days. Today's phones don't support WTLS anymore neither, it doesn't
give real security as the operator can still wiretap to what the user does.

Hi,
It's been 4 months now that I made a no small contribution to provide
wtls functionality to kannel. I have not received any feedback (positive or
negative) and apparently there is no interest in it. It is a pitty, since
apart from the development effort, there was also significant time spent to
port everything to kannel style and sources. I was misled to believe that
this would be worthwhile. Frankly, I cannot understand how kannel could ever
claim to be a wap gateway, without supporting one of the 3 major protocols
(WSP, WTP & WTLS).
It is therefore with regret that I retract this contribution. Since it
was never accepted by kannel, the original commercial rights remain in
effect (InAccess Networks and myself) and no part of the patch offered can
be used in part or as a whole without the expressed permission of the
authors.
Regretfully,
Nikos Balkanas

Dear friends,
This is a long overdue contribution to kannel's wap. It will provide
wtls functionality. It has been thoroughly tested in Solaris, and compiles
cleanly in Linux.
I used indent to format the structure, so a lot of the differences
will be formatting. Nevertheless, there is a lot of code in there that
needed to make it work. Let me know if the cvs diff is the best way to
submit it, or whether a tarball of the sources would be better. I've have
had some issues with cvs diff in the past, so if you get any compilation
warnings, I may have to go with a tarball.
In particular it will provide:
A) Supported MACs:
SHA_0,
SHA_40,
SHA_80,
SHA_NOLIMIT,
MD5_40,
MD5_80,
MD5_NOLIMIT
MIA's:
SHA_XOR_40
B) Supported Ciphers:
RC5_CBC_40,
RC5_CBC_56,
RC5_CBC,
DES_CBC,
DES_CBC_40
MIA's:
NULL_bulk,
TRIPLE_DES_CBC_EDE,
IDEA_CBC_40,
IDEA_CBC_56,
IDEA_CBC
C) Supported Keys:
RSA_anon
MIA's:
RSA_anon_512,
RSA_anon_768,
RSA_NOLIMIT,
RSA_512,
RSA_768,
ECDH_anon,
ECDH_anon_113,
ECDH_anon_131,
ECDH_ECDSA_NOLIMIT
Keys might seem a shortcoming, but I have yet to see a mobile that
doesn't support RSA_anon. I do expect that a few of the rest of the keys are
supported as well (i.e. RSA_anon_512, RSA_anon_768) just didn't have the
chance to test them.
Please vote and decide,
Nikos
