  32         <p>I have  earlier covered the basics of trusted timestamping using the
  33 'openssl ts' client.  See blog post for
  34 <a href="http://people.skolelinux.org/pere/blog/Public_Trusted_Timestamping_services_for_everyone.html">2014</a>,
  35 <a href="http://people.skolelinux.org/pere/blog/syslog_trusted_timestamp___chain_of_trusted_timestamps_for_your_syslog.html">2016</a>
  36 and
  37 <a href="http://people.skolelinux.org/pere/blog/Idea_for_storing_trusted_timestamps_in_a_Noark_5_archive.html">2017</a>
  38 for those stories.  But some times I want to integrate the timestamping
  39 in other code, and recently I needed to integrate it into Python.
  40 After searching a bit, I found
  41 <a href="https://dev.entrouvert.org/projects/python-rfc3161">the
  42 rfc3161 library</a> which seemed like a good fit, but I soon
  43 discovered it only worked for python version 2, and I needed something
  44 that work with python version 3.  Luckily I next came across
  45 <a href="https://github.com/trbs/rfc3161ng/">the rfc3161ng library</a>,
  46 a fork of the original rfc3161 library.  Not only is it working with
  47 python 3, it have fixed a few of the bugs in the original library, and
  48 it has an active maintainer.  I decided to wrap it up and make it
  49 <a href="https://tracker.debian.org/pkg/python-rfc3161ng">available in
  50 Debian</a>, and a few days ago it entered Debian unstable and testing.</p>
  51
  52 <p>Using the library is fairly straight forward.  The only slightly
  53 problematic step is to fetch the required certificates to verify the
  54 timestamp.  For some services it is straight forward, while for others
  55 I have not yet figured out how to do it.  Here is a small standalone
  56 code example based on of the integration tests in the library code:</p>

  64 get trusted timestamps.
  65
  66 The license of this code is the same as the license of the rfc3161ng
  67 library, ie MIT/BSD.

 121 <p>The code fetches the required certificates, store them as temporary

 123 disk and ask 'openssl ts' to verify the timestamp.  A timestamp is
 124 around 1.5 kiB in size, and should be fairly easy to store for future
 125 use.</p>

 150         <p>A few days, I rescued a Windows victim over to Debian.  To try to
 151 rescue the remains, I helped set up automatic sync with Google Drive.
 152 I did not find any sensible Debian package handling this
 153 automatically, so I rebuild the grive2 source from
 154 <a href="http://www.webupd8.org/">the Ubuntu UPD8 PPA</a> to do the
 155 task and added a autostart desktop entry and a small shell script to
 156 run in the background while the user is logged in to do the sync.
 157 Here is a sketch of the setup for future reference.</p>
 158
 159 <p>I first created <tt>~/googledrive</tt>, entered the directory and
 160 ran '<tt>grive -a</tt>' to authenticate the machine/user.  Next, I
 161 created a autostart hook in <tt>~/.config/autostart/grive.desktop</tt>
 162 to start the sync when the user log in:</p>
 163
 164 <p><blockquote><pre>
 165 [Desktop Entry]
 166 Name=Google drive autosync
 167 Type=Application
 168 Exec=/home/user/bin/grive-sync
 169 </pre></blockquote></p>
 170
 171 <p>Finally, I wrote the <tt>~/bin/grive-sync</tt> script to sync
 172 ~/googledrive/ with the files in Google Drive.</p>
 173
 174 <p><blockquote><pre>
 175 #!/bin/sh
 176 set -e
 177 cd ~/
 178 cleanup() {
 179     if [ "$syncpid" ] ; then
 180         kill $syncpid
 181     fi
 182 }
 183 trap cleanup EXIT INT QUIT
 184 /usr/lib/grive/grive-sync.sh listen googledrive 2>&1 | sed "s%^%$0:%" &
 185 syncpdi=$!
 186 while true; do
 187     if ! xhost >/dev/null 2>&1 ; then
 188         echo "no DISPLAY, exiting as the user probably logged out"
 189         exit 1
 190     fi
 191     if [ ! -e /run/user/1000/grive-sync.sh_googledrive ] ; then
 192         /usr/lib/grive/grive-sync.sh sync googledrive
 193     fi
 194     sleep 300
 195 done 2>&1 | sed "s%^%$0:%"
 196 </pre></blockquote></p>
 197
 198 <p>Feel free to use the setup if you want.  It can be assumed to be
 199 GNU GPL v2 licensed (or any later version, at your leisure), but I
 200 doubt this code is possible to claim copyright on.</p>
