Assuring a mail comes from the same (unkbown) sender. The cracker of the
"improved" MS DRM system used it this way: his mails (actually, newsgroup
postings) were signed with a key, and someone who wanted to give him
information about the DRM system could do so in secret by encrypting it
to his key. But for obvious reasons he didn't want to become known.
