<p class="MsoNormal"> #1371: Simplify passing the public key to the RP<o:p></o:p></p>
<p class="MsoNormal"> David proposed sending the key in a base64url-encoded JWK rather than sub_jwk<o:p></o:p></p>
<p class="MsoNormal"> Mike said that JWKs can have more fields than just the key and the order can vary<o:p></o:p></p>
<p class="MsoNormal"> Whereas the JWK Thumbprint results in a stable subject identifier<o:p></o:p></p>
<p class="MsoNormal"> Mike said that using attributes to identify the end-user enables attacks<o:p></o:p></p>
