Struct WebAuthnSignature 

pub struct WebAuthnSignature {
    pub credential_id: String,
    pub authenticator_data: String,
    pub client_data_json: String,
    pub signature: String,
}

Available on crate feature signatures only.

WebAuthn/FIDO2 signature data.

Contains the assertion response from a WebAuthn authenticator. All fields are base64-encoded as per the Codex specification.

Verification

To verify a WebAuthn signature:

1. Decode all base64 fields
2. Parse client_data_json and verify the challenge matches the document ID
3. Verify the authenticator data flags and counter
4. Verify the signature over authenticator data + SHA-256(client data JSON)

Fields

credential_id: String

Base64-encoded credential ID.

Identifies the credential used for signing.

authenticator_data: String

Base64-encoded authenticator data.

Contains the RP ID hash, flags, and signature counter.

client_data_json: String

Base64-encoded client data JSON.

Contains the challenge (document ID), origin, and type.

signature: String

Base64-encoded signature.

The cryptographic signature over the authenticator data concatenated with the SHA-256 hash of the client data JSON.

Implementations

impl WebAuthnSignature

pub fn new( credential_id: impl Into<String>, authenticator_data: impl Into<String>, client_data_json: impl Into<String>, signature: impl Into<String>, ) -> Self

Create a new WebAuthn signature.

Trait Implementations

impl Clone for WebAuthnSignature

fn clone(&self) -> WebAuthnSignature

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WebAuthnSignature

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for WebAuthnSignature

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for WebAuthnSignature

fn eq(&self, other: &WebAuthnSignature) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for WebAuthnSignature

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
