   Can't find this curve in https://www.iana.org/assignments/jose/jose.xhtml, is it proprietary?

   The algorithm seems quite well known, but there's no "Curve Name" defined for "JSON Web Key Elliptic Curve". I can implement support anyway.

   I guess you also want support for JWS @peppelinux ? If so, what's the alg (also undefined in the registry).

   According to https://github.com/latchset/jwcrypto/blob/main/jwcrypto/jwk.py the name of crv might also be BP-256. jwcrypto does not seem to have any signature algorithms defined.

   There's also https://datatracker.ietf.org/doc/draft-ietf-jose-fully-specified-algorithms/ to provide some guidance for the signature algorithm.
