I'd love to see some specifics about this, but the ssh-keygen man page is quite vague. It says rsa is "protocol version one," and dsa is "protocol version 2."

Now, what does that mean, actually?

Oh, I suppose. If you live in a high crime area of town you'd be putting bars on your windows and double, or triple-locks on your doors. In other parts of twon a simple, good lock will do. And, in some parts of the planet it's still possible to leave doors unlocked without a problem.

So, suit yourself. Not every machine is an NSA crypto cracker, and not every machine needs to be locked like Fort Knox, imho.

Besides, what are you doing exposing your keys to anyone coming along??
