So here's the deal... I've got a brand new never-used raspberry pi sitting around doing nothing and was wondering what I could do with it other than just let it sit around and collect dust. My thought for it was to create a fully functional and secure DNM computer complete with an installation of Whonix and the latest versions Electrum and PGP ready to go. I'd like to include a MAC address changer as well but need advice as to where to find a good one. Basically I want this thing to be plug-and-play so that all a person has to do is boot into it and know it/they are secure. Help me flesh this out. What am I missing in the way of security essentials, yada, yada, yada... ? Any ideas are welcome. This is an open-ended project and may turn into something available for sale at some point.
you can't really do that, you're asking us for help and then selling on our ideas/help.
anyways, yeah i can write a bash script to install all the shit you need if you want, it's not hard, the whonix thing is a little harder because it requires two instances unless you mean running the rpi as the gateway but then you'd need another PC, anyways, if the project stays free and open i'm happy to help.
Software:
Pidgin + OTR
Tor
I2P
Electrum (even though it's centralized it's what you want i guess?)
PGP
Firefox
Proxychains
irssi/weechat
MACChange
none of this is hard to make honestly
you might want to include some iptables fuckery to DROP all traffic except tor. something like this: https://help.ubuntu.com/community/TorDedicatedUser
