why not? public-private encyrption is the right tool for a number of
jobs... A better solution in the context of shell accounts at least is
simply not to use passwords. when you create an account for someone. you
have them generate dsa keypair they send you the public part in clear text
email, you drop it in their ~/.ssh/authorized_keys they log in with the
private half. no passwords went over the wire. A similar thing can be
done with ssl webservers and client keys.
