<p>If you already certified the Tails signing key with your own key, you can skip this step and start [[downloading and verifying the USB image|expert#download]].</p>
In this step, you will download and verify the *Tails signing key* which is the OpenPGP key that is used to cryptographically sign the Tails USB image.
<p>To learn how to create yourself an OpenPGP key, see <a href="https://riseup.net/en/security/message-security/openpgp/gpg-keys">Managing OpenPGP Keys</a> by <em>Riseup</em>.</p>
Import the OpenPGP key of [[!wikipedia Chris_Lamb_(software_developer) desc="Chris Lamb"]], a former Debian Project Leader, from the Debian keyring into your keyring:
It is also possible to verify the certifications made by other people. Their name and email address appear in the list of certification if you have their key in your keyring.
<div class="caution"> <p>If the verification of the certification failed, then you might have downloaded a malicious version of the Tails signing key or our instructions might be outdated. Please [[get in touch with us|support/talk]].</p> </div>
<div class="tip"> <p>The line <code>175 signatures not checked due to missing keys</code> or similar refers to the certifications (also called <i>signatures</i>) made by other public keys that are not in your keyring. This is not a problem.</p> </div>
