am curious about your pgp key,

which can be fetched from some key server, or from
http://fragrieu.free.fr/fgrieu_gmail.asc


it appears to have been generated recently (11/july/2007),

Yes, it is dedicated to my usenet identity. My motivation is
that I have recently been impersonated on sci.crypt; with moderate
thinking or expertise it was easy to distinguish the forgeries
from genuine posts of mine, but I feared it could become worse,
thus wanted to provide others with a mean to ascertain that
something actually comes from me.

and is an unusual size (1984) to choose for current key use,
(even for pgp 2.x)

I have memories of a problem with 2048 bit keys in some old
PGP code, thus chose the next lower 64-bit mutiple.
