<p>I’ve (re)discovered how to become S/MIME compliant. I am now suprised how easy it was. Some years ago it was far more difficult. Now I’m able to sign and encrypt my emails.</p>
<h2 id="why-is-it-important">Why is it important?</h2>
<p>Signing: it tell the other with an aboslute certitude the writer of the mail is <em>you</em> or at least used your computer.</p>
<p>Encrypt: because sometimes you need to be 100% sure a conversation remains private.</p>
<h2 id="how-to-proceed">How to proceed?</h2>
<li>Get a certificate signed by a CA: <a href="">click here to get a free one</a>,</li>
<li>open the file,</li>
<li>empty your trash, put the file in the trash, secure empty trash,</li>
<li>use Mail instead of online gmail. Now you should see these icons:

<p><em>n.b.</em>: if you use gmail, you and work not alway with a Mac, you should consider to try the <a href="">gmail S/MIME firefox addon</a>.</p>
