key.asc generation from apt ring

["Javier-Elias Vasquez-Vivas" <jevv.cr@gmail.com>]

Hi,

As I don't have internet access at home, I use apt-mirror  (very nice
tool by the way) to keep an up to date repositorie under an USB disk.

I downloaded the debian and gnuab key ascii files (*key*.asc), however
the debian-marillat key I grabed on the machine that I can connect to
Internet not from a key ascii file, but from the server procedure
described int the following pages:

http://linux.about.com/library/cmd/blcmdl1_gpg.htm

As the other machines at home don't have internet access I can't apply
such procedures of authenticating against the key server and such, so
I'd like to be able to generate a key ascii file for the marillat
packages from the machine including the key in its key ring, so that I
can just "apt-key add <marillat-key.asc>" into the other ones.

Is this possible?  And if so, how can I do it?

Thanks,
