To the lurkers: if anyone wants this code, feel free to ask me
directly... or Justin, perhaps.

Yeah. Actually, that's what prompted me to send it to you before
I had time to make it really decent -- the stage was set for more
unnecessary overlaps.

That said, please forgive the sorry messy state of the code
(I just noticed qca.h from one package was not the same of the
other). It's my first hack at it and it was done in a hurry.

Yeah, but a) some of my users insist on 2048+ bit keys, which take
quite a lot longer and b) it's nice to have an option to threading,
since not everything is thread-safe everywhere, some people may
have complied Qt without threading support,... you get the picture.

Yep, that's me.

Short answer: over-overworked. You don't want to hear the long
answer. :)

But now I'm back. In any event, thanks for QCA1 -- it made my job
way easier. I'm preparing the site for my app (called "Kapanga")
that uses it and soon you'll see where you code ended up. Ah,
your name's in the credits too.

Looking for the future, let's make QCA2 rock. Count on me to help.

- -K.
