Hey, curious if you saw https://github.com/privacy-scaling-explorations/circom-ecdsa-p256 or https://github.com/zkwebauthn/webauthn-halo2 when searching for a circom or Halo 2 p256 circuit respectively, and if you did, what trouble did you have using them?

hey! we have seen the work from pse and zk webauthn, but we chose to use sp1/zkvm based approach just as a proof-of-concept to show how we could verify the signatures from apple's hardware on-chain efficiently. in practice, we would likely choose to use either the libraries you've suggested or wait for on-chain verification for sp1 proofs!
