CBOR is also used on WebAuthn, usage in a web spec means to me that someone smart considered it a sane choice -- and more importantly that the format is here to stay.

CBOR’s RFC: https://tools.ietf.org/html/rfc7049 https://tools.ietf.org/html/rfc7049 And Amazon has picked it up as a first class citizen in some of their IoT Core features. It’s definitely here to stay.

It's great CBOR is accepted in wider area, but I am personally curious why WebAuthn choose CBOR instead of JSON. WebAuthn is a web browser feature, and why W3C would introduce a new data exchange format in their specs? Maybe WebAuthn needed a binary data type?

  I'm guessing a binary format is nice when interacting with a device.. Anybody know if (and why) U2F uses CBOR?
