Well, you folks were so helpful with regards to doing the CVS without a
shell question, that I'm back with another one. 8)

I'd like to let my users generate their own private/public key pair so
they can set their own password, etc, then they can just email me the
public key and I can install it on my server. However, I'd like to add
two restrictions. I'd like the key to be at least 2048 bit, and I don't
want to allow passwordless keys. If they send me their public key, is
there a way I can gleam this information from it?

I'm suspecting that the answer to finding out whether or not it is
passwordless is no, that I can't do it without the private key?
