Welcome to Vault PHP Client's documentation!
============================================

.. toctree::

This is a PHP client for Vault - a tool for managing secrets.

Quick start
-----------

.. code-block:: php

    <?php

    use Vault\AuthenticationStrategies\AppRoleAuthenticationStrategy;
    use Vault\AuthenticationStrategies\UserPassAuthenticationStrategy;
    use Vault\AuthenticationStrategies\TokenAuthenticationStrategy;
    use Vault\Client;
    use Laminas\Diactoros\RequestFactory;
    use Laminas\Diactoros\StreamFactory;
    use Laminas\Diactoros\Uri;

    // Creating the client
    $client = new Client(
        new Uri('http://127.0.0.1:8200'),
        new \AlexTartan\GuzzlePsr18Adapter\Client(),
        new RequestFactory(),
        new StreamFactory()
    ); // Using alextartan/guzzle-psr18-adapter and laminas/laminas-diactoros

    // Define Vault Namespace (optional)

    $client->setNamespace('my-namespace');

    // Authenticating using userpass auth backend.

    $authenticated = $client
        ->setAuthenticationStrategy(new UserPassAuthenticationStrategy('test', 'test'))
        ->authenticate();

    // Authenticating using approle auth backend.

    $authenticated = $client
        ->setAuthenticationStrategy(new AppRoleAuthenticationStrategy(
            'd4131206-384f-75fa-11d6-55d1d63c07c0',
            'cac86a12-c566-3932-09f3-5823ccdfa606'
        ))
        ->authenticate();

    // Authenticating using token auth backend.
    $authenticated = $client
        ->setAuthenticationStrategy(new TokenAuthenticationStrategy('463763ae-0c3b-ff77-e137-af668941465c'))
        ->authenticate();

List secret keys
----------------

To retrieve a set of keys in a secret, after authentication, use the ``keys()`` method, passing in the database’s path, with the suffix ``/metadata``, as you can see in the highlighted section below.

.. code-block:: php
   :linenos:
   :emphasize-lines: 29,30,31

    <?php

    use Vault\AuthenticationStrategies\TokenAuthenticationStrategy;
    use Vault\Client;
    use Zend\Diactoros\RequestFactory;
    use Zend\Diactoros\StreamFactory;
    use Zend\Diactoros\Uri;

    // Creating the client
    $client = new Client(
        new Uri('http://127.0.0.1:8200'),
        new \AlexTartan\GuzzlePsr18Adapter\Client(),
        new RequestFactory(),
        new StreamFactory()
    ); // Using alextartan/guzzle-psr18-adapter and zendframework/zend-diactoros

    // Authenticating using token auth backend.
    // Request exception could appear here.
    $authenticated = $client
        ->setAuthenticationStrategy(new TokenAuthenticationStrategy('463763ae-0c3b-ff77-e137-af668941465c'))
        ->authenticate();

    if (!$authenticated) {
        // Throw an exception or handle authentication failure.
    }

    // Request exception could appear here.
    /** @var \Vault\ResponseModels\Response $response */
    $response = $client->keys('/secret/metadata');

    $data = $response->getData(); // Raw array with a list of secret keys.

    // ...

On success, an associative array is returned, similar in structure to the example below.
This array contains an element named ``keys``, whose value is an array of the secret's keys.

.. code-block:: php

    [
        "keys": [
            "hello"
        ]
    ]
Fetching a secret
-----------------

.. code-block:: php

    <?php

    use Vault\AuthenticationStrategies\TokenAuthenticationStrategy;
    use Vault\Client;
    use Laminas\Diactoros\RequestFactory;
    use Laminas\Diactoros\StreamFactory;
    use Laminas\Diactoros\Uri;

    // Creating the client
    $client = new Client(
        new Uri('http://127.0.0.1:8200'),
        new \AlexTartan\GuzzlePsr18Adapter\Client(),
        new RequestFactory(),
        new StreamFactory()
    ); // Using alextartan/guzzle-psr18-adapter and laminas/laminas-diactoros

    // Authenticating using token auth backend.
    // Request exception could appear here.
    $authenticated = $client
        ->setAuthenticationStrategy(new TokenAuthenticationStrategy('463763ae-0c3b-ff77-e137-af668941465c'))
        ->authenticate();

    if (!$authenticated) {
        // Throw an exception or handle authentication failure.
    }

    // Request exception could appear here.
    /** @var \Vault\ResponseModels\Response $response */
    $response = $client->read('/secret/database');

    $data = $response->getData(); // Raw array with secret's content.

    // ...
