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