there’s no need to use these parameters. But for some use cases, this is valuable information that can be dynamically provided. (The Key ID (“kid”) can also be dynamically provided, if appropriate to the use case.)<o:p></o:p></span></p>

<p class="MsoNormal">Almost certainly I’m just missing something obvious, but I’m having trouble understanding why the jku and x5u header claims exist. The idea is I get a message and believe the message’s assertion about where I should go to get the cert
