Thanks for the replies, everyone. So what about a solution like Yubikey
NEO? I read on their site that you can generate a keypair and put it on the
yubikey. But what I'm a little confused about is, once you have the public
and private key on the card, how do you use it to encrypt/sign/decrypt
things? Excuse my lack of knowledge on this. It all seems pretty cool, and
I'm just trying to wrap my head around it.
