<p>I mention that I first tried to remove the password from my pdf using
the excellent pdf manipulation program <a
href="https://okular.kde.org/en-gb/">Okular</a> recommended to me by <a
href="https://hackerpublicradio.org/correspondents/0225.html">Dave
Morriss</a>.</p>
<p>After some googling I found the following <a
href="https://www.cyberciti.biz/faq/removing-password-from-pdf-on-linux/">solution
to my password protected PDF.</a></p>
<p>The command line program I used to remove the password from my pdf
was <a href="https://qpdf.sourceforge.io">qpdf</a>.</p>
<p>This is <a href="https://qpdf.readthedocs.io/en/stable/cli.html">the
Man page documentation for qpdf</a></p>
<p>This is the command I used to remove the password in my pdf</p>
<pre><code>Qpdf &#x2014;decrypt protected.pdf unprotected.pdf</code></pre>
