and/or the file attachment. The receiver is allowed only 3 tries, and
if all are wrong, the message is removed from the site.
So it's pretty simple to use, (simple enough that busy doctors are

The doctor calls the patient, and arranges the question and answer,
and then can send files encrypted as attachments.
An MITM attack is not practical as the doctor and patient share the
secret over a different channel (phone, person to person in the

I pointed this out to a doctor who uses this, and his response was
basically that it's "not in his threat model", (although it was much
