After having received some positive feedback on our presentation on the topic at hand at ClueCon '22, let's go through a more detailed run-down of all steps required, from a cryptographic point of view, in order to first become a fictive STIR/SHAKEN CA (Certification Authority), then to begin issuing signed certificates for various (also fictive) … Continue reading How To Generate Self-Signed STIR/SHAKEN Certificates
