How, if at all, do SSH keys differ from asymmetric keys used for other purposes?
How, if at all, do SSH keys differ from asymmetric keys used for other purposes, e.g. email signing?

Well, the hard-drive on my laptop died (it was displaying "SMART failure prediction -- Hard-disk Drive dailure might be imminant).
