Yes, that's primarily what I'd imagine cold storage to be: an offline machine with keys that never leave the device.

Though I'd not conmect the machine to any kind of network, just because it means less things to secure.

<p>Lets say I want to generate my own transactions and sign them myself via my computer. Signing them in the computer would require me to input my private key, which would compromise the key.

Is it possible to sign a transaction programmatically via a connected cold storage wallet?
