[sf-lug] passphrase

[Alex Kleider]

Thank you Rick for that explanation: I had read about the
public/private key pairs and how that cleverly allows encryption
without a preliminary exchange of encryption keys but it had never
occurred to me about the problem of keeping the private key truly
private while it sits on a multiuser machine. Now I get how the pass
phrase fits into the picture.
