Turns out the ASN.1 wrapping for ECDSA signatures is for historical U2F reasons. [The spec calls this out as such](https://www.w3.org/TR/webauthn-2/#sctn-signature-attestation-types): > Note: As CTAP1/U2F [authenticators](https://www.w3.org/TR/webauthn-2/#authenticator) are already producing signatures values in this format, CTAP2 [authenticators](https://www.w3.org/TR/webauthn-2/#authenticator) will also produce signatures values in the same format, for consistency reasons. Given this context, there's not really anything to be done here without risking breaking compatibility with U2F authenticators. -- GitHub Notification of comment by MasterKale Please view or discuss this issue at https://github.com/w3c/webauthn/issues/1829#issuecomment-1379450255 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
