Subject: secp256k1 curve and algorithm registered for JOSE use
IANA has registered the “secp256k1” elliptic curve in the JSON Web Key Elliptic Curve registry and the corresponding “ES256K” signing algorithm in the JSON Web Signature and Encryption Algorithms registry. This curve is widely used among blockchain and decentralized identity implementations.
The registrations were specified by the COSE and JOSE Registrations for WebAuthn Algorithms specification, which was created by the W3C Web Authentication working group and the IETF COSE working group because WebAuthn also allows the use of secp256k1. This specification is now in IETF Last Call. The corresponding COSE registrations will occur after the specification becomes an RFC.
