README

A Laravel package with 2 main functions:

1. Remove secrets from Logs. Prevent from secrets being leaked in logs.
2. Load kubernetes/docker secrets from file

Demo & Usage

1. Remove secrets from Logs

Without laravel-secrets. secretpassword leaked in log

[2022-07-20 16:11:34] local.NOTICE: This is a notice level message.
[2022-07-20 16:11:34] local.ALERT: Can't connect with https://login:secretpassword@example.com

With laravel-secrets, secretpassword is redacted before send log

[2022-07-20 16:11:34] local.NOTICE: This is a notice level message.
[2022-07-20 16:11:34] local.ALERT: Can't connect with https://login:[redacted]@example.com

2. Read secret from file.

return [
    'connections' => [
        'mysql' => [
            'driver' => 'mysql',
            'port' => env('DB_PORT', '3306'),
            'username' => laravel_secrets('/run/secrets/db/username', env('DB_USERNAME')),
            'password' => laravel_secrets('db/password', env('DB_PASSWORD')),
        ],
]

Minimum requirements

• PHP 8.0
• Laravel 8.0

Installation

composer require gawsoft/laravel-secrets

Install package assets

php artisan vendor:publish --provider="Gawsoft\LaravelSecrets\LaravelSecretsServiceProvider"

Configuration

Example config/secrets.php:

<?php

return [
    'strategy' => [
        # String with which secrets value will be replaced
        'redaction' => '[redacted]',
        # Default strategy to load secrets
        'handler' => \Gawsoft\LaravelSecrets\Secrets\Providers\ContainerStrategy::class,

        # Config for strategy
        'config' => [
            # Default path to your secrets
            # - when you run laravel_secrets('db/password') -> Will check path /run/secrets/db/password
            # - when you run laravel_secrets('/secrets/db/password') -> Ignore default path and check /secrets/db/password
            'path' => '/run/secrets/',
            # If you encrypt secret all encrypted string will start with this string.
            # This string cannot be empty!
            'encrypted_prefix' => 'encrypted:',
        ]
    ],
    // Remove from logs sensitive keys
    'logs' => [
        // When set empty whitelist array, all config values will be redacted.
        // When set min one value only this value will be redacted.
        'whitelist' => [
          //  'app.key',
          //  'mail.mailers.smtp.password',
          //  'database.connections.mysql.password'
        ],
        'blacklist' => [
            'app.name',
            'logging.level',
        ],
    ]
];

1. Read secrets from file

When you install laravel in docker or kubernetes for security reason your devops team inject secrets to file in the container. This package will read this secret with function laravel_secrets.

laravel_secrets('<PATH-TO-FILE>', '<DEFAULT-VALUE>');

2. Read encrypted secrets from file

You can also encrypt secrets with Laravel App Key and auto encrypt after loaded encrypted string to Laravel config.

# Encrypt password by artisan command
echo "abc" > /tmp/password
cat /tmp/password | php artisan laravel-secrets:encrypt --stdin

# Decrypt password
echo "encrypted:eyJpdiI6InhQbEhUREJQa21mcW85M0tYSEhhOUE9PSIsInZhbHVlIjoiY2pXZ0lqUlY4YVoydDdyZzVHak9XUT09IiwibWFjIjoiMWFlZjA4MGIyN2Q2YmEwMzc4ZGNjNTYzYTgyOTNiMzFiOWM0OTVmZWFkNGYzZTFiNDAwM2Y1NzgyYWJlMDEwMCIsInRhZyI6IiJ9" > /tmp/encrypted
cat /tmp/encrypted | php artisan laravel-secrets:decrypt --stdin

3. Remove secrets from Logs

During logs process in Laravel my package will remove sensitive data from log message. Default will remove all values saved in all configs. You can change this options in config/secrets.php via set whitelist and blacklist.

#config/secrets.php
return [
    // Remove sensitive keys from logs 
    'logs' => [
        // When set empty whitelist array, all config values will be redacted.
        // When set min one value only this value will be redacted.
        'whitelist' => [
          //  'app.key',
          //  'mail.mailers', # Alle mailers secrets will be redacted
          //  'database.connections.mysql.password'
        ],
        // Do not redact values from blacklist. Those values will show in logs
        'blacklist' => [
            'app.name',
            'logging.level',
        ],
    ]
];

Tests

RoadMap

• Add Strategy for AWS Secret Manager
• Add Strategy for Hashicorp Vault

How to write new strategy

1. Create new file LaravelSecrets\Secrets\Providers\MySecretProvider.php
2. Write your driver

<?php

namespace MyCompany\MyPackage\LaravelSecrets\Secrets\Providers\MySecretProvider;

use Gawsoft\LaravelSecrets\Abstracts\SecretsProviderAbstract;
use Gawsoft\LaravelSecrets\Interfaces\SecretProviderInterface;


class ContainerStrategy extends SecretsProviderAbstract implements SecretProviderInterface
{
    function getSecret(string $name): string | null
    {
        // Get secret from your source
    }

}

1. Register as default strategy in configs/secrets.php

return [
    'strategy' => [
        ...
        'handler' => \MyCompany\MyPackage\LaravelSecrets\Secrets\Providers\MySecretProvider::class,
        ...
    ]
