If any entity actually is able and willing to spend enough effort,
money, resources to dig me up at my home, force me to hand over my
keys, to shut up and to keep posting my warrant canary at the bottom of
my emails, then why should they not be capable of doing any one of the
following:

 - Also present warrants to my family & friends, forbiding them to ring
the alarm (remember that they can certainly forbid people to speak out.
the canary works on the assumption that they can not force us--at
least not legally--to lie).

 - intercept said email

 - send a second email stating "sorry, false alarm, in fact she / he's
all good!" (no signatures of any kind either)

 - also force me to tell my family all is good

 - since they got my keys and passwords, just log on to said account on
my behalf every week

In fact I felt that this was barely more secure, but certainly more
complex than the simple email-signature canary.


I will elaborate on my view on the topic in a later email--possibly
tonight.

At the time of writing, no warrants have ever been served to me, Niklas
Lemcke, nor am I under any personal legal compulsion concerning the
CipherShed project. I do not know of any searches or seizures of my
assets.
