[[!meta title="Transition to a new OpenPGP signing key"]]
Tails is transitioning to a new OpenPGP signing key.
The signing key is the key that we use to:
Sign our official ISO images.
Certify the other [[OpenPGP keys|doc/about/openpgp_keys]] used by the project.
<p>The previous signing key is safe and, to the best of our knowledge, it
has not been compromised.</p>
<p>We are doing this change to improve our security practices when
manipulating such a critical piece of data.</p>
<li>The old key can still be used to verify Tails 1.3 ISO images.</li>
<li>The new key will be used to sign ISO images starting from Tails 1.3.1.</li>

The new signing key is itself signed by the old signing key. So you can transitively trust this new key if you had trusted the old signing key.
To verify that the new key is correctly signed by the old key, you can execute the following command:
gpg --check-sigs A490D0F4D311A4153E2BB7CADBB802B258ACD84F
The output should include a signature of the new key by the old key such as:
sig! 0x1202821CBE2CD9C1 2015-01-19 Tails developers (signing key) <tails@boum.org>
In this output, the status of the verification is indicated by a flag directly following the "`sig`" tag. A "`!`" indicates that the signature has been successfully verified.
