Hi,
I solved this by calling a function in OpenSSL that does exactly what I needed. The
module already linked to OpenSSL for other things, so this seemed like a straight-forward
solution.
Regards,
Peter

For outbound I currently have a modparam to set
the flow token key.
There is absolutely no reason why this should be user configurable,
replicated across multiple Kamailio instances, or survive Kamailio
restart as each flow is unique and should be re-established if there is
a server failure.
I would much prefer to have Kamailio just select its own key at
start-up. Is there any simple way to get Kamailio to select a 20-octet
crypto random string?
Hello Peter,
there is no API to get this certain data at the moment. During startup the
core initialize the glibc rand and our fastrand pseudo-random number generator
from /dev/urandom. Then you can call e.g. in your module the rand, random or
fastrand functions and use this to generate your random string. For an example
have a look to generate_random_secret in auth/auth_mod.c.
