Another way? (Score 1)

I was thinking.. if you could find the dir with the keys and just get a list of it. (for example, sshd is in /etc which is usually gloabally listable), you could look at the files date and then go thru the sshd source code to find where it generates the key. It probably uses the time/date to seed the random number generator, you could repeat this process with that timestamp you found on the file and have it spit back the key!
