Why?! Why would I do that?! I do like to think of myself as a bit altruistic,
but seriously, why would I go through all that effort? Thanks for making me
smile. It does a person good.

Furthermore, I am a bit tired of this subject, forgive me for not answering most
of what you say. I get the impression you're not picking up on what I'm trying
to say, and that becomes a bit tiresome.

If you would link[1] to the mailing list archives I wouldn't have to open the
(what Thunderbird calls) "message source" to visually compare the Message-ID on
a likely message.

Anyway, that wasn't such a long mail. It sure doesn't contain your suggestion.
You're really doing a lot of extra interpretation and inference if you take that
suggestion from:

To me, it says that 4k or 8k keys are not the weak spot of a cryptosystem. And
that we should discuss weak spots on this list. Thank you for your contribution
in that. But it sure as hell doesn't say that a smartcard keeps you safe when
you're working on a compromised system.

Glad we agree on that at least.
