Using Academic Signature under
Presently the "Highest End Security" against US and other
government agencies may be using Academic Signature for document
enciphering and exchange under TAILS
.(Please excuse my hubris, but this is what I believe.) Using
TAILS is somewhat inconvenient, so you may want to use this only
if you suspect you are specifically and personally targeted by any
of these organizations.
As we know today this doesn't only happen to the bad guys but
unfortunately also to very honorable people.
Apparently nowadays it doesn't take more than to google for TAILS
or TOR just once to be
labeled as extremist by the US administration. From there it might
be a very short step to being labeled as terrorist.
Current Info: They did it
again, deep sigh, ever again, the developer version of
wxWidgets has broken dependencies in the current TAILS 2.4 :-(
So as a workaround, again, I
compiled a version of academic signature on a seasoned ubuntu
which works on TAILS 2.4. You can find it here:
of the archive, my ECDSA-signature
and my ECC-timestamp.
Just unzip and use the local copy. Hopefully the procedure to
compile from source, outlined below, will work again soon.....
Since TAILS is based on a seasoned Debian and I develop Academic
Signature on a recent Ubuntu(based on a recent Debian), chances
are my binaries won't run on TAILS because some libraries don't
You will have to compile Academic Signature yourself in a
persistent folder in this case under TAILS.
(Thanks Dirk for pointing out some issues, I tried to
address them and included some of your comments below.)
a) Set a root password on booting TAILS.
b) Make sure to have a persistent folder on your TAILS.
c) Download the Academic Signature source archive and my GnuPG
signature to the persistent folder.
d) Check my GnuPG Signature of the Academic Signature
source.(GnuPG is included in TAILS).
e) Unzip the source archive.
f) Run 'sudo apt-get update'
(optional) Check for the presence of
wxWidgets in Tails e.g. using synaptic.(wxWidgets should be
included in TAILS).
g) In Synaptic (Applications, System Tools, Administration),
select the following three packages: make, g++ and
libwxgtk3.0-dev. A number of additional dependencies will be
taken care of automatically. This will take up about 75Mb. of
additional disk space.
This step has
to be redone, if you want to build aca_sig again in a new TAILS
3 a) Change to Aca-sig's download directory and
call as usual "./configure" then "make".
Upon successful building, you use the local binary and mark it
as executable. Installation to the system via "sudo make
install" should be omitted since it would only install for this
session and would not persist in TAILS - just work with the
local copy of the binary and the local helper subdirectories
"x_secrets" and "key_tray" in the persistent folder.
3 option b) Change to Aca-sig's download directory and
directly call the hand-made makefile "make release".
Depending on the the version of Debian your TAILS is based on, you
may or may not have to delete the explicit link to lX11 in the
makefile to successfully build Academic Signature. This is a
recurrent nuisance in wxWidgets.
Upon successful building, you use the local binary and mark it as
executable. Installation to the system via "sudo make install"
should be omitted since it would only install for this session and
would not persist in TAILS - just work with the local copy of the

"key_tray" in the persistent folder.
Both methods work for me with the current TAILS 1.6 without
You may want to get
some practice with TAILS (and Academic Signature, TOR,
GnuPG,...) even if you are not specifically targeted. This would
be a useful exercise to be prepared for the worst......
As I read in a discussion forum: The Gulags and KZs of the 20th
century were full of innocent people who had "nothing to hide".
May honesty, openness, tolerance and democracy prevail,
we don't need Orwellian thought
control by administrations that tortured,
let known torturers run
around on the loose
and tell the world about
