Hi,

I’m the author of Jsign, an alternative to signtool for signing binaries, and I’m wondering if it would be possible to integrate it with Signotaur. Is there a documentation of the Signotaur API that could be called by Jsign for signing?

Hi Emanual

There isn’t an api - we provide our own client tool to replace signtool - it used grpc to talk to the server - we do not have any plans to make that public.

Oh ok, the web server is just for the admin UI, I thought it also exposed a REST API. That would be a nice addition if you are looking for new features 🙂
