Technical Summary

   CBOR Web Token (CWT) is a compact means of representing claims to be
   transferred between two parties.  The claims in a CWT are encoded in
   the Concise Binary Object Representation (CBOR) and CBOR Object
   Signing and Encryption (COSE) is used for added application layer
   security protection.  A claim is a piece of information asserted
   about a subject and is represented as a name/value pair consisting of
   a claim name and a claim value.  CWT is derived from JSON Web Token
   (JWT) but uses CBOR rather than JSON.

Working Group Summary

   The document was not controversial, and received a great deal of
   review from many participants.  A first WGLC revealed a few issues
   that required enough changes that a second WGLC was made.  The second
   WGLC attracted fewer comments, but the document is largely unchanged
   from the first WGLC, and we believe it to be in good shape.

   There are multiple implementations of this document, and the examples
