[VoiceOps] STIR/SHAKEN implementation - CLI tool, HTTP API server and C library

[Daniel-Constantin Mierla]

Hello,

I noticed the discussion about STIR/SHAKEN that happened on this forum a
few weeks ago and for quite some time I had in my todo list the task to
add support for those extensions to Kamailio SIP server, but with no
real pressure to deploy them here in Europe, I kept postponing for a
while (also, some people did it already for Kamailio using embedded
scripting languages Lua or Python).

Anyhow, as I saw the discussion here, it became fresh again and I
searched the web, but I could not find any free/open tools to
test/validate implementations, so it looked a bit like chicken-egg
problem, therefore I created recently such a project, written in Go
language, with option to build a C static or shared library.

It is still very fresh code, not much tested, now with ES256 signing
algorithm based on golang native support, no interoperability done with
other applications. The project is available at:

  * https://github.com/asipto/secsipidx

To be able to enable older versions of PBX/SIP servers to support
STIR/SHAKEN extensions, besides the C library exports, there is an
application that can run as CLI tool or HTTP API server to check or
generate Identity headers. I haven't tested at all on Windows, but I
expect that golang ensures good portability, not using anything OS
specific in the code.

I thought it worth announcing it here, in case someone wants to play
with, suggest improvements or even contribute to make it easier to use
on their specific deployments.

Cheers,
Daniel
