The rfc (4253) mentions in section 8 that I_C and I_S as the *payload* of the SSH_MSG_KEXINIT. Now, is this the compressed or the uncompressed contents of those messages? I understand from section 6 (binary packet protocol) that payload refers to the compressed contents. But i can also see that openssh uses the uncompressed contents. Can someone clarify?

I'd say uncompressed, simply because it makes more sense to me. :) I agree this point is underspecified; I wish we'd noticed it before the drafts were turned into RFCs.... I note that section 8 also says I_C is C's SSH_MSG_KEXINIT message and I_S is S's SSH_MSG_KEXINIT message that have been exchanged before this part begins. To me, the "message" is the uncompressed version, though I can certainly see it as a defensible stance that it is the compressed, or even compressed and encrypted, version. /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse@rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B From bounces-ietf-ssh-owner-secsh-tyoxbijeg7-archive=lists.ietf.org@NetBSD.org Wed Jan 31 03:19:45 2007 Received: from [10.91.34.44] (helo=ietf-mx.ietf.org) by megatron.ietf.org with esmtp (Exim 4.43) id 1HCAgz-00050A-63 for secsh-tyoxbijeg7-archive@lists.ietf.org; Wed, 31 Jan 2007 03:19:45 -0500 Received: from mail.netbsd.org ([2001:4f8:4:7:2e0:81ff:fe52:9ab6]) by ietf-mx.ietf.org with esmtp (Exim 4.43) id 1HCAgw-0000Kg-By for secsh-tyoxbijeg7-archive@lists.ietf.org; Wed, 31 Jan 2007 03:19:45 -0500 Received: by mail.netbsd.org (Postfix, from userid 0) id 6611E63B17A; Wed, 31 Jan 2007 08:19:24 +0000 (UTC) X-Original-To: ietf-ssh@netbsd.org Delivered-To: ietf-ssh@netbsd.org Received: from real.edu.ee (server.real.tln.edu.ee [195.250.188.110]) by mail.netbsd.org (Postfix) with ESMTP id 89C4D63B152 for ; Wed, 31 Jan 2007 08:19:23 +0000 (UTC) Received: from localhost (unknown [127.0.0.1]) by real.edu.ee (Postfix) with ESMTP id 1E0E8A4A6B for ; Wed, 31 Jan 2007 08:18:53 +0000 (UTC) Received: from real.edu.ee ([127.0.0.1]) by localhost (server [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 28964-01-11 for ; Wed, 31 Jan 2007 10:18:52 +0200 (EET) Received: by real.edu.ee (Postfix, from userid 30) id ABED8A55C5; Wed, 31 Jan 2007 10:18:31 +0200 (EET) To: ietf-ssh@netbsd.org Subject: Can I trust you?
