We have it slightly different but otherwise close to yours

Subject: Re: [OpenSIPS-Users] stir shaken verification
Thank you very much. I have the same file, and verification is still failing.
Perhaps my config:
$var(found) = cache_fetch("local", $identity(x5u), $var(cert));
if (!$var(found) || !stir_shaken_check_cert("$var(cert)")) {
rest_get( "$identity(x5u)", $var(cert), $var(ctype), $var(http_rc));
if ($rc<0 || $var(http_rc) != 200) {
send_reply(436, "Bad Identity Info");
exit;
}
cache_store("local", $identity(x5u), $var(cert), 60);
}
stir_shaken_verify( "$var(cert)", $var(err_sip_code), $var(err_sip_reason));
if ($rc < 0) {
xlog("stir_shaken_verify() failed: $var(err_sip_code), $var(err_sip_reason)
\n");
send_reply( $var(err_sip_code), $var(err_sip_reason));
exit;
}
I figured this much:
$var(cert) is a public certificate downloaded from $identity(x5u), if it does
not exists in local cache it gets pulled and stored,
stir_shaken_check_cert("$var(cert)") is generating these errors:
ERROR:stir_shaken:load_cert: Failed to parse certificate
ERROR:stir_shaken:w_stir_check_cert: Failed to load certificate ( because the
entry does not exists in local cashdb)
this forces the download of the public cert from $identity(x5u) and store in
local cashdb
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.
Also, I have minimize cache_store down to 1 second and after that second call
with same $identity(x5u) should generate same errors , but it is not.
an example at shaken-not-stirred page have :
rest_get( "$identity(x5u)", "$var(cert)",
$var(ctype), $var(http_rc));
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) .

Hi Marcin,
I suspect you are correct that its how you are decoding the ca cert file from
iconectiv.
attached is what we have currently and it works in our production enviroment.
If the maillist strips out that attachment let me know. You can reach me
directly at jjack...@aninetworks.net<mailto:jjack...@aninetworks.net>

Joseph, Thank you very much for your respond.
I have downloaded and apply new sti-ca file but certificate validation fails.
INFO:stir_shaken:verify_callback: certificate validation failed: certificate
signature failure
INFO:stir_shaken:w_stir_verify: Invalid certificate
DBG:core:comp_scriptvar: int 26 : -8 / 0
[1637] stir_shaken_verify() failed: 437, Unsupported Credential
Perhaps I am not processing the sti-ca file properly.
I am testing this with a valid token , in fact test calls are coming from major
cellular carrier in US and the verification fails.
I can see curl download the public cert, storing it in local cache and then
attempt to verify, but it fails.
Upon next call with same token, the public cert is pulled from local cache and
still fails.

Hi Marcin,
We have a process that downloads the CA list from iconectiv nightly, decodes
the jwt and stores the certs in a single file in /etc/ssl/sti-ca/sti-ca.pem
Here is the opensips modparam
#stir and shaken
loadmodule "stir_shaken.so"
modparam("stir_shaken", "verify_date_freshness", 300)
modparam("stir_shaken", "auth_date_freshness", 300)
modparam("stir_shaken", "e164_strict_mode", 0)
#list of root certs for stir / shaken verification
modparam("stir_shaken", "ca_list", "/etc/ssl/sti-ca/sti-ca.pem")
This is on opensips v3.1.11

Subject: [OpenSIPS-Users] stir shaken verification
Opensips version 3.1.5
I am having some issues with stir_shaken setup. I am sure this not an issue
with the module, but me.
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. I
guess my question is how do I use this file or any other cert file as "ca_list"
and/or "ca_dir" .
After weeks and hundreds attempts I was unsuccessful, and I was unable to
locate any document explaining preparation/setup/steps to setup verification.
All I get is :
ERROR:stir_shaken:load_cert: Failed to parse certificate
ERROR:stir_shaken:w_stir_verify: Failed to load certificate
on INVITE with valid identity header.
When I remove or replace "ca_list" file with something bogus opensips does not
even start with errors:
ERROR:stir_shaken:init_cert_validation: Failed to load trustefd CAs
ERROR:core:init_mod: failed to initialize module stir_shaken
I would really appreciate some guidance on this one.
