Technical Summary

   The CBOR Object Signing and Encryption (COSE) specification defines
   cryptographic message encodings using Concise Binary Object
   Representation (CBOR).  This specification defines algorithm
   encodings and representations enabling RSA algorithms to be used for
   COSE messages.  Encodings for the use of RSASSA-PSS signatures,
   RSAES-OAEP encryption, and RSA keys are specified.

Working Group Summary

  This is an AD sponsored draft as the WG felt it was not important to 
  keep the WG open for this draft, however there was sufficient support
  to have this progress as AD sponsored.  This will be used by
  W3C WebAuth and the FIDO alliance.

Document Quality

  There are implementations and planned use.  I have no concerns
  with document quality.  


Rich Salz is the shepherd, Kathleen Moriarty is the responsible AD.
