Any suggestions on how to implement public key recovery with WebCrypto ECDSA?
How is (r,s) encoded in the output buffer of sign? Is it just r = [0,32) and s = [32,64) for curve = P-256 (docs) ?
sign
r = [0,32)
s = [32,64)
curve = P-256
Seams like elliptic.js implements the recovery and it should be possible to import the recovered public key via jwk back into WebCrypto ...
