as a general option for the rest of us, it would be cool to have a USB version of Armory that is easy to implement. i'm not sure though once the USB is connected to desktop/laptop how its protected from malware residing on the desktop/laptop.
this is the reason why I boot from the USB and no storage component of the host computer is part of the file system in the running OS
so then how do get access to the unsigned tx; a second USB stick?
I have the full Linux system with offline Armory in an encrypted partition on the same stick as the fat32 partition I use for transaction exchange.
- when a system is booted from the stick no processes on the possibly infected system are running
- when the stick is inserted into a running system everything except the data partition is encrypted and can't be changed
- malware on the online computer could destroy my offline OS but not install anything into it
so the unsigned tx has is located in the unencrypted data portion of the USB stick and can be accessed after you've booted up a desktop computer from the encrypted Linux OS on the USB stick, correct? but where is the Satoshi client/blockchain that you need Armory to access?
