A simple and powerful package to manage your application secrets safely.

Secure-CM loads configurations from .env, .yaml, or .json files, automatically encrypts sensitive keys before saving, and decrypts them on load. It is designed for modern development workflows, especially for SaaS products and multi-environment deployments that require a clear separation of configuration and secrets.

• Multi-Format Support: Load configurations from .env, .yaml, or .json files.

• Automatic Encryption: Sensitive values are automatically encrypted using AES-256-CBC.

• Environment-Specific Configs: Manage separate configurations for development, production, staging, etc.

• Easy to Use: Simple, intuitive API for loading, getting, setting, and saving configurations.

• Version Control Friendly: Store encrypted configuration files safely in your version control system.

• SaaS Products: Manage different database credentials, API keys, and feature flags for multiple tenants or environments.

• Multi-Environment Deployments: Keep your production, staging, and development configurations separate and secure.

• Open Source Projects: Allow contributors to use a template configuration without exposing sensitive project keys.

npm install secure-cm

1. Create a configuration file.

   Create a config directory in your project root. Inside, create a file for your environment, e.g., development.json.

   ./config/development.json

   {
     "DB_HOST": "localhost",
     "DB_USER": "root",
     "DB_PASS": "my-secret-password",
     "API_KEY": "another-secret-key"
   }

2. Initialize the manager and load your config.

   You'll need a 32-character secret key for encryption. You can store this in a secure place like your hosting environment's secret manager or an environment variable.

   const SecureCM = require('secure-cm');
   
   // WARNING: Do not hardcode your secret key in production. 
   // Use an environment variable or a secret management service.
   const secretKey = process.env.CONFIG_SECRET_KEY || 'a-secure-32-character-secret-key';
   
   const configManager = new SecureCM({
       env: 'development',
       secretKey: secretKey,
       configDir: './config' // Optional, defaults to ./config
   });
   
   // Specify which keys are sensitive and should be encrypted
   configManager.load(['DB_PASS', 'API_KEY']);
   
   // Access your configuration
   console.log('DB Host:', configManager.get('DB_HOST')); // 'localhost'
   console.log('DB Password:', configManager.get('DB_PASS')); // 'my-secret-password' (decrypted)

3. Save an encrypted version of your config.

   Run this once to create an encrypted version of your config file. You can then safely commit this file to version control.

   // This will encrypt 'DB_PASS' and 'API_KEY' and save a new file.
   configManager.save('json'); 
   

   Your development.json will now look like this:

   ./config/development.json

   {
     "DB_HOST": "localhost",
     "DB_USER": "root",
     "DB_PASS": "iv_hex:encrypted_password_hex",
     "API_KEY": "iv_hex:encrypted_key_hex"
   }

   Now, you can safely commit this file. The original plain-text values are never exposed.

Creates a new instance.

• options <Object>

  • env <string> The current environment (e.g., 'production'). Default: 'development'.

  • configDir <string> The directory where config files are located. Default: './config'.

  • secretKey <string> Required. A 32-character string used for encryption and decryption.

Loads the configuration file for the specified environment.

• sensitiveKeys <string[]> An array of keys within the configuration that should be treated as sensitive and decrypted upon loading.

Retrieves a configuration value.

• key <string> The key of the value to retrieve.

Sets a configuration value in memory.

• key <string> The key of the value to set.

• value <any> The value to set.

Encrypts sensitive keys and saves the entire configuration to a new file.

• format <string> The format to save the file in ('json', 'yaml', or 'env'). Default: 'json'.
