These samples demonstrate how to invoke Google Cloud KMS from PHP.

1. Enable APIs - Enable the KMS API and create a new project or select an existing project.

2. Download The Credentials - Click "Go to credentials" after enabling the APIs. Click "New Credentials" and select "Service Account Key". Create a new service account, use the JSON key type, and select "Create". Once downloaded, set the environment variable GOOGLE_APPLICATION_CREDENTIALS to the path of the JSON key that was downloaded.

3. Clone the repo and cd into this directory

   $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
   $ cd php-docs-samples/kms
   

4. Install dependencies via Composer. If composer is installed locally:

   $ php composer.phar install
   

   If composer is installed globally:

   $ composer install
   

5. Execute the snippets in the src/ directory by running:

   $ php src/SNIPPET_NAME.php
   

   The usage will print for each if no arguments are provided.
