cryptography/passkey_keypair library

Classes

PasskeyAuthentication

The result of a WebAuthn assertion (navigator.credentials.get and friends).

PasskeyKeypair

A passkey signer (SIP-9). The private key never leaves the authenticator; signing is delegated to a PasskeyProvider, so every signing method is async.

PasskeyProvider

Bridges to a platform WebAuthn/credentials API. The actual key lives in the authenticator, so this is implemented by the host app (browser via JS interop, iOS/Android via platform channels) and supplied to PasskeyKeypair.

PasskeyRegistration

The public key and credential id returned when registering a new passkey.

Functions

findCommonPublicKey(List<PasskeyPublicKey> a, List<PasskeyPublicKey> b) → PasskeyPublicKey

Returns the single public key present in both lists, throwing if there is not exactly one. Used with two PasskeyKeypair.signAndRecover results.
