README

hash verification using a nonce & verifying the hmac from the URL for a laravel application

Installation

composer require dpc/hash-verifier

The service provider will be automatically discovered in Laravel 5.5. Publish the config file by running:

php artisan vendor:publish --provider="Dpc\HashVerifier\AuthValidatorServiceProvider"

This will create a validator.php in your config folder.

Do not use your secret directly in config file. Instead fetch it from the .env or server environment variables.

Usage

Inject the nonce generator contract and/or HMAC validator contract in your class:

  public function __construct(NonceContract $generator)
    {
        $this->generator = $generator;
    }

To generate a nonce:

$nonce = $this->generator->generateNonce($user)

The nonce will be automatically stored in the session with key as `nonce'. To retrieve it call:

$nonce = $this->generator->getStoredNonce();

Ensure that you do not mutate the nonce.

To verify whether the nonce matches

$nonceMatches = $this->generator->matches($user, $nonce);

To validate if the hmac matches the components of the URL:

$result = $this->validator->validate($uriComponents));
