<p>oggi voglio fare l&#8217;Hacker&#8230;in fondo lo siamo un po&#8217; tutti!</p>
<p>Vi spiego come rimuovere le protezioni dai file PDF, molto spesso non servono per motivi &#8220;nocivi&#8221; ma anche solo per poter aggiungere delle note o dei segnalibri per facilitarne la consultazione.</p>
<p>Su Linux esistono due modi.</p>
<h3><strong>MODO 1: CONOSCO LA PASSWORD</strong></h3>
<p>Ovviamente questo caso è relativo allo 0,00001% di voi!</p>
<p>Se conoscete la password del vostro documento è semplice, esistono diversi programmi che fanno al caso vostro:</p>
<p><strong>pdftk</strong> &#8211; Molto utile per la manipolazione dei file PDF.<br />
<strong>qpdf</strong> &#8211; Converte da PDF a PDF .<br />
<strong>xpdf-utils</strong> &#8211; Suite con diversi tool per manipolazione di PDF<br />
<strong>Print to a file</strong> &#8211; Software Evince per stampare direttamente su File</p>
<p><strong>PDFTK</strong></p>
