https://phpseclib.com/docs/publickeys

Installation

You can install the package via composer:

composer require laranex/laravel-biometric-auth

You can publish and run the migrations with:

php artisan vendor:publish --tag="biometric-auth-migrations"
php artisan migrate

You can publish the config file with:

php artisan vendor:publish --tag="biometric-auth-config"

This is the contents of the published config file:

<?php

return [
    'table' => env('BIOMETRIC_AUTH_TABLE', 'biometrics'),

    // You will need to be explicit about the encryption padding and hash algorithm when working with RSA keys.
    // For the rest of the algorithms, the package will automatically detect with the help of phpseclib.
    'rsa' => [
        'encryption_padding' => \phpseclib3\Crypt\RSA::SIGNATURE_PKCS1,
        'hash_algorithm' => 'sha256',
    ],
];

Usage

// Use Laranex\LaravelBiometricAuth\Traits\HasBiometrics in your Authenticable Model such as User, Admin
class User extends Authenticatable {
    use Laranex\LaravelBiometricAuth\Traits\HasBiometrics;
}

// Register a new biometric
$user->createBiometric("Base 64 encoded public key");

// Create a challenge for biometric authentication
$biometric = Laranex\LaravelBiometricAuth\Facades\LaravelBiometricAuth::getBiometric("UUID of a biometric");

// Verify the signature
Laranex\LaravelBiometricAuth\Facades\LaravelBiometricAuth::verifyBiometric("UUID of a biometric", "Signature");

// Get the user of verified biometric key
$user = Biometric::find("UUID of a biometric")->instance;

// Revoke a biometric
$user->revokeBiometric("UUID of a biometric");
