As of $(date +%F), aninix.net has not received any National Security Letters or FISA court orders, and we have not been subject to any gag order(s) by a FISA court, or any other similar court(s) of any government.

The next two updates should be on or before:
|
|
* `date -d @$(( $time + 7776000 )) +%F`
|
|
* `date -d @$(( $time + 15552000 )) +%F`
|

|
Recent news:
|
|
* $(RecentNews "$alJazeera" "$alJazeeraDate")
|
|
* $(RecentNews "$npr" "$nprdate")

|
To verify this message, on the terminal import our public key from $keyserver and verify the canary:
|
|
$ gpg --keyserver $keyserver --recv-key $key
|
|
$ gpg2 --fingerprint $key
|
|
$(gpg2 --fingerprint $key)
|
|
$ gpg --verify <(curl -s $canary) 2>&1 | grep 'Good signature'
|
|
gpg: Good signature from "DarkFeather <ircs://aninix.net:6697/DarkFeather>" [ultimate]
|
|
|
|
There will most likely be other lines in the output from that last command, but as long as it says "Good signature", the verification worked correctly.
