<p class="MsoNormal">I'm getting confused. I thought the reason to encrypt/sign UserInfo is to implement end2end message security. I don't see the UserInfo response as another kind of assertion intended to be passed around. The ID Token is intended for that
purpose, right?<br>
<br>
Therefore I don't see a need to add aud or iss claims to the UserInfo response.<br>

And perhaps aud as well to prevent an accidental transfer to a third party.<br>
It is not a MUST but still is a good practice.<br>

<p class="MsoNormal">Hi guys,<br>
<br>
For UserInfo responses encoded as JWTs - which of the standard JWT<br>
claims, apart from the mandatory "sub", do you choose to include?<br>
<br>
<a href="http://tools.ietf.org/html/draft-ietf-oauth-json-web-token-12#section-4.1" target="_blank">http://tools.ietf.org/html/draft-ietf-oauth-json-web-token-12#section-4.1</a><br>
<br>
It appears to me that in order for the UserInfo to be suitable for<br>
passing around as a JWT it should include at least the "iss" claim.<br>
<br>
Thanks,<br>
<br>
Vladimir<br>
