<title type="html"><![CDATA[[QUESTION] YubiKey 4 CCID touch sensor]]></title>

<content type="html" xml:base="https://forum.yubico.com/viewtopic.php?t=2169&amp;p=8190#p8190"><![CDATA[
I have configured Yubikey in PIV/CCID mode. When I imported the certificates and their keys, I have specified, <div class="codetitle"><b>Code:</b></div><div class="codecontent">--touch-policy=always</div><br /> From that point on, Linux has required me to touch the YubiKey whenever a cryptographic operation is requested (it alerts You by blinking). But on Windows, the YubiKey happily performs the operation without me touching it. <br /><br />I have YubiKey 4 with PIV applet version 4.2.7 and one certificate in slot &quot;Digital Signature&quot;. I tested the setup with Pageant-CAC and WinScp (works nicely!), albeit this should have no relevance, as the touch policy should be enforced by the applet. OpenPGP applet correctly requires touch when signing.<br /><br />Is there any way to force the YubiKey to require touch before letting me use the key? Is there a source code for the PIV applet (like there is for the PGP one) ?<p>Statistics: Posted by <a href="https://forum.yubico.com/memberlist.php?mode=viewprofile&amp;u=4149">rkapl</a> — Mon Jan 18, 2016 8:47 pm</p><hr />
