Hello everyone, my name is Sebastian Huebner. Currently I work on my thesis at the Institute of Computer Science in Potsdam. As a part of my thesis I analyze the possibilities of authentication between the different parts of a SIP-Infrastructure. In this context I'm going to implement an UA which is able to use PGP-Authentication. I've noticed, there are some data structures and functions in PJSIP which provide PGP-Authentication, but as far as I can tell they are not implemented yet. Now I'm trying to implement this functionality by myself using the given types and functions. For that reason, I have the following questions: Is there a special contact person who is responsible for PGP in PJSIP? Are you probably interested in my implementation of PGP-Authentication in PJSIP? Kind regards, Sebastian
