I've never seen encrypted fax. :-o

And why it is rarely used except for interdepartmental secure

Notice they don't provide a "Buy" link. Instead they provide a "Request
a Quote" link, because this stuff is priced outside the consumer market.
That's why there are online faxing services that offer encrypted
transmission via faxing or conversion to a passworded and encrypted PDF
or TIFF file for e-mail delivery.

Most e-mail users have never heard of encrypting their e-mails, either.
They just use what their e-mail client provides, by default. Not until
they decide it might be nice to digitally sign their e-mails which
requries an e-mail certificate might they then discover e-mails (from
others using their public half of their cert key) can be encrypted. How
many e-mails have you gotten that were digitally signed?

I can count them with my hands.

Even for those
that were, were they signed with certs that merely had the e-mail
address of the sender? Free e-mail certs usually only include the
e-mail address of the cert holder (because that's how the CA validates
delivery of the cert), but that's not much to identify a sender. To get
more info into the cert means having to buy one to add more data fields
into the cert.
