Subject: [SR-Users] Kamailio 5.5 STIR SHAKEN private key buffer size error

Hi,

I am trying STIR/SHAKEN using libstirshaken in Kamailio 5.5.

I used a self signed certificate as this is just a test in the local docker
environment. However, when I try to add identity with private key
(stirshaken_add_identity_with_key), I get "[error_code: 447] Buffer for key
from file /tmp/cert/private.pem too short (2000 <= 3247)"

I have tried using 2048 and 4096 size

root(a)5907e44bd056:/tmp/cert# openssl rsa -in private.pem -text -noout |
grep "Private-Key"
RSA Private-Key: (4096 bit, 2 primes)

Could you tell me what is wrong with the certificate?

Kamailio version:

root(a)5907e44bd056:/usr/local/kamailio/etc/kamailio# kamailio -v
version: kamailio 5.5.4 (x86_64/linux) 469465

Error:

This error is  seems to come from libstirshaken (
https://github.com/signalwire/libstirshaken/blob/master/include/stir_shaken.h
line 46) and has nothing to do with Kamailio. Please open a bug with
signalwire who owns and maintains this library.

Per my understanding this library is bit old and uses many deprecated
functions and needs updating. As a general rule of thumb, in PEM format,
the private key size in bytes is roughly 80% (4/5) of key size in bits e.g.
4096 bit private key size would be roughly,

(4096 * 4) / 5 ~= 3277 byes

which is too big for allowed size (2000 byes) in libstirshaken. So, either
increasing the allowed size in libstirshaken OR reducing your SSL key bit
length to e.g. 1024 may work.

Thank you.

Note that kamailio has another module that offer StIR/SHAKEN

this one I maintain and if there is any issue found, I am going to fix it.

All the best,
Daniel

Hi Daniel,

I have following the installation as mentioned in the SecSIPId module page (
https://www.kamailio.org/docs/modules/5.5.x/modules/secsipid.html#secsipid.f.=
secsipid_add_identity
)

I am able to load the module without any error. However, when I initiate a
call I can see the following error:

0(12956) ERROR: {1 9581 INVITE lzss4D1pl5NkPYfdEZ24OlrXHjnEmWiA} secsipid
[secsipid_mod.c:330]: ki_secsipid_add_identity(): failed to get identity
header body (-151)


Below is the kamaili configuration where identity needs to be added before
it dispatch to service provider trunk:

secsipid_add_identity("$fU", "$rU", "C", "", "
http://pinaiyam.8ksamples.com/certificate.pem", "/tmp/cert/private.pem");



Regards

*Maharaja Azhagiah*

Hello,

the error code means that the format of the key is invalid:

=C2=A0 - https://github.com/asipto/secsipidx/blob/main/secsipid/secsipid.go#L=
46

If you haven't retrieved from someone, then note that is not the usual
tls/ssl key format, see:

=C2=A0 - https://github.com/asipto/secsipidx#keys-generation

Cheers,
Daniel
