Friends : While some of this discussion may be annoying, the level of
knowledge, commitment to ones position and the frankness on this list amazes
me. thanks to all those who add to the knowledge base
*My status : *
- I do not worry about an NSA style attack. Where I live, the big bro
wouldn't take all the trouble checking and messin my _network_ to get stuff
out of me !! :-( They use more conventional ones ..... and .... If they
were messing with my _network_ I admit that it would be be futile to fight
- As I write, I think I _do_not_ have a neighbourhood kid problem....but
that potential exists
- I use Win XP
- I have use Cryptography - GPG (the Gpg executable on my Hard disk) for
encrypting files and some mail...mostly commercial ....stuff... still not
rocket launching (thankfully so probably !!)
- I do use secure websites for logging in and out but that is a different
game I suppose ?
*some practical questions with the above as given *
- Would It help if I had two networks to connect to ...say the home one and
the office one ?
- I have very limited restriction on downloading stuff from the gnupg web
sites (files bigger than 30 MB may be a problem...but nothing on GPG / PGP /
front ends / Mail clients seem to be > 30 MB
- what should I check ....but downloading GPG and related material from each
of these networks
- any other things to note ?
Thanks in advance
