Abstract

   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.

1.  Introduction

   The CBOR Object Signing and Encryption (COSE) [I-D.ietf-cose-msg]
   specification defines cryptographic message encodings using Concise
   Binary Object Representation (CBOR) [RFC7049].  This specification
   defines algorithm encodings and representations enabling RSA
   algorithms to be used for COSE messages.

1.1.  Requirements Notation and Conventions

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in RFC
   2119 [RFC2119].

2.  Signature Algorithms

2.1.  RSASSA-PSS

   The RSASSA-PSS signature algorithm is defined in [RFC3447].

   The RSASSA-PSS signature algorithm is parameterized with a hash
