Download raw auth data

[osresearch]

Describe the problem you'd like to have solved

For validating attestation signatures it is necessary (I think?) to have the raw authData available. The debugger website doesn't have a way to access it that I can see.

Describe the ideal solution

Add an additional Download button, similar to the ones for the signature, x509 cert, etc.

Alternatives and current work-arounds

A more flexible approach would be to also make the CBOR library and attestation response object available as globals for access in the javascript console.
