The W3C Web Authentication (WebAuthn) specification and the FIDO
Alliance FIDO2 Client to Authenticator Protocol (CTAP) specification
use CBOR Object Signing and Encryption (COSE) algorithm identifiers.
This specification registers the following algorithms (which are used
by WebAuthn and CTAP implementations) in the IANA "COSE Algorithms"
registry: RSASSA-PKCS1-v1_5 using SHA-256, SHA-384, SHA-512, and
SHA-1; and Elliptic Curve Digital Signature Algorithm (ECDSA) using
the secp256k1 curve and SHA-256. It registers the secp256k1 elliptic
curve in the IANA "COSE Elliptic Curves" registry. Also, for use
with JSON Object Signing and Encryption (JOSE), it registers the
algorithm ECDSA using the secp256k1 curve and SHA-256 in the IANA
"JSON Web Signature and Encryption Algorithms" registry and the
secp256k1 elliptic curve in the IANA "JSON Web Key Elliptic Curve"
registry.
This document is a product of the CBOR Object Signing and Encryption Working
Group of the IETF.
This is now a Proposed Standard.
