<div>
<p>Thank you very much. I have the same file, and verification is still failing. Perhaps my config:</p>
<p><br>
</p>
<p>$var(found) = cache_fetch("local", $identity(x5u), $var(cert));<br>
if (!$var(found) || !stir_shaken_check_cert("$var(cert)")) {<br>
rest_get( "$identity(x5u)", $var(cert), $var(ctype), $var(http_rc));<br>
if ($rc<0 || $var(http_rc) != 200) {<br>
send_reply(436, "Bad Identity Info");<br>
exit;<br>
}<br>
cache_store("local", $identity(x5u), $var(cert), 60);<br>
}<br>
<br>
stir_shaken_verify( "$var(cert)", $var(err_sip_code), $var(err_sip_reason));<br>
if ($rc < 0) {<br>
xlog("stir_shaken_verify() failed: $var(err_sip_code), $var(err_sip_reason) \n");<br>
send_reply( $var(err_sip_code), $var(err_sip_reason));<br>
exit;<br>
}<br>
</p>
<p><br>
</p>
<p>I figured this much: <br>
</p>
<p>$var(cert) is a public certificate downloaded from $identity(x5u), if it does not exists in local cache it gets pulled and stored,</p>
<p>stir_shaken_check_cert("$var(cert)") is generating these errors:<br>
</p>
<p>ERROR:stir_shaken:load_cert: Failed to parse certificate<br>
ERROR:stir_shaken:w_stir_check_cert: Failed to load certificate ( because the entry does not exists in local cashdb)</p>
<p>this forces the download of the public cert from $identity(x5u) and store in local cashdb<br>
</p>
<p>second attempt does not generate this errors, however calls with deferent identity header and url for public cert should generate same errors again as the public cert from new url is not in local cashdb, but it is NOT generating same error.</p>
<p>Also, I have minimize cache_store down to 1 second and after that second call with same $identity(x5u) should generate same errors , but it is not.</p>
<p>an example at shaken-not-stirred page have : <br>
</p>
<pre class="x_wp-block-preformatted">rest_get( "$identity(x5u)", "$var(cert)",
$var(ctype), $var(http_rc));</pre>
<p>but this fails a start-up with error ERROR:core:fix_cmd: Param [2] expected to be a variable so I removed the double quotes from around $var(cert) .</p>

<p>Joseph, Thank you very much for your respond.</p>
<p><br>
</p>
<p>I have downloaded and apply new sti-ca file but certificate validation fails.</p>
<p>INFO:stir_shaken:verify_callback: certificate validation failed: certificate signature failure<br>
INFO:stir_shaken:w_stir_verify: Invalid certificate<br>

<p><br>
</p>
<p>Perhaps I am not processing the sti-ca file properly.</p>
<p><br>
</p>
<p>I am testing this with a valid token , in fact test calls are coming from major cellular carrier in US and the verification fails.</p>
<p>I can see curl download the public cert, storing it in local cache and then attempt to verify, but it fails.</p>
<p>Upon next call with same token, the public cert is pulled from local cache and still fails.</p>

<p>Opensips version 3.1.5<br>
</p>
<p>I am having some issues with stir_shaken setup. I am sure this not an issue with the module, but me.<br>
</p>
<p><code class="x_x_x_function">stir_shaken_auth works just fine and I am able to sign the calls, however I was unable to find any document how to use a ca file available for download at iconectiv/download-list as well as via API. They do come in as jwt file,
but after little manipulation individual certificates can be extracted, and the first one is the root certificate; I think, and the rest are trusted STI-CA.
</code><code>I guess my question is how do I use this file or any other cert file as
</code>"ca_list" and/or "ca_dir" . <br>
</p>
<p>After weeks and hundreds attempts I was unsuccessful, and I was unable to locate any document explaining preparation/setup/steps to setup verification.<br>
</p>
<p>All I get is : <br>
</p>
<p>ERROR:stir_shaken:load_cert: Failed to parse certificate<br>
ERROR:stir_shaken:w_stir_verify: Failed to load certificate<br>
on INVITE with valid identity header.<br>
</p>
<p>When I remove or replace "ca_list" file with something bogus opensips does not even start with errors:</p>
<p>ERROR:stir_shaken:init_cert_validation: Failed to load trustefd CAs<br>
ERROR:core:init_mod: failed to initialize module stir_shaken</p>
<p>I would really appreciate some guidance on this one.</p>
