Would you already have the passkey / other information, or do you need to pull this out of elsewhere?

I think it would be good to differentiate between clientDataJSON
and CollectedClientData
(see passkey-rs) and keep clientDataJSON
as type ArrayBuffer
, consistent with the webauthn spec
export type ClientDataJSON = { | |
type: string; | |
challenge: string; | |
origin: string; | |
crossOrigin?: boolean; | |
tokenBinding?: { | |
id?: string; | |
status: "present" | "supported" | "not-supported"; | |
}; | |
}; | |
export type ClientDataType = "webauthn.get" | "webauthn.create" | "payment.get" | |
export type CollectedClientData = { | |
type: ClientDataType; | |
challenge: string; | |
origin: string; | |
crossOrigin?: boolean; | |
[key: string]: any | |
}; | |
export type ClientDataJSON = Uint8Array; |

Can we add a useState
for the network so the user can toggle between Devnet / Localnet and Testnet / Mainnet in the future?

I think it may be better for this to be just the plain verification method (i.e., not for webauthn signatures). See secp256r1_ecdsa_sigs.rs. And then the webauthn verify
/ verifyWebAuthnSignature
methods can be added to PartialAuthenticatorAssertionResponse
to be consistent with aptos-core

Same as above, I think it may make more sense to move the verify methods here to be consistent with aptos-core
but lmk if you feel differently. Here's webauthn.rs
for reference.
