challenge
特性为
PublicKeyCredentialCreationOptions
dictionary is a
BufferSource
used as
a cryptographic challenge
. This is randomly generated then sent from the relying party's server. This value (among other client data) will be signed by the authenticator, using its private key, and must be sent back for verification to the server as part of
AuthenticatorAttestationResponse.attestationObject
.
注意：
When the credential is retrieved with a
navigator.credentials.get()
call, the signature of the challenge is contained in
AuthenticatorAssertionResponse.signature
.
注意： A challenge will be at least 16 bytes long.
challenge = publicKeyCredentialCreationOptions.challenge
A
BufferSource
which is at least 16 bytes long. Contains a cryptographic challenge emitted from the relying party's server which must be signed by the authenticator's private key and sent back (within the
response
) to the relying party's server for verification.
var publicKey = {
challenge: new Uint8Array(26) /* this actually is given from the server */,
rp: {
name: "Example CORP",
id : "login.example.com"
},
user: {
id: new Uint8Array(26), /* To be changed for each user */
name: "jdoe@example.com",
displayName: "John Doe",
},
pubKeyCredParams: [
{
type: "public-key",
alg: -7
}
]
};
navigator.credentials.create({ publicKey })
.then(function (newCredentialInfo) {
// send attestation response and client extensions
// to the server to proceed with the registration
// of the credential
}).catch(function (err) {
console.error(err);
});
