# Noir WebAuthn

Provides `webauthn::verify_signature` function that verifies a WebAuthn signature(also called passkey signature).

## Installation

In your _Nargo.toml_ file, add the version of this library you would like to install under dependency:

```toml

[dependencies]

webauthn = { tag = "v0.36.0", git = "https://github.com/olehmisar/noir_webauthn" }

```

Note on version compatibility with Noir

The version of this library matches the version of Noir. The patch version may be different if a bugfix or a new feature is added for the same version of Noir. E.g., this library version v0.36.0 and this library version v0.36.1 are compatible with [email protected].

## Usage

```rs

let result = webauthn::verify_signature(

    // [u8; 32] - x coordinate of WebAuthn public key generated by `credentials.create`

    public_key_x,

    // [u8; 32] - y coordinate of WebAuthn public key generated by `credentials.create`

    public_key_y,

    // [u8; 64] - signature generated by `credentials.get`

    signature,

    // BoundedVec - clientDataJSON generated `credentials.get`

    client_data_json,

    // BoundedVec - authenticatorData generated `credentials.get`

    authenticator_data,

    // [u8; 32] - challenge generated `credentials.get`

    challenge,

    // u32 - index of challenge in clientDataJSON

    challenge_index,

);

assert(result, "webauthn signature verification failed");

```
