Using Private Keys in Environment Variables

You can use environment variables to safely handle sensitive information like private keys with JWTs (JSON Web Tokens). This approach allows for secure transfer and handling of credentials across different platforms, including local development environments and cloud deployments. By using environment variables, you can avoid hardcoding sensitive data into your codebase, reducing the risk of security breaches. The Vonage Node SDK example demonstrates how to securely handle private keys as strings by encoding them in base64 and storing them in environment variables. This approach enables flexible deployment across various platforms while maintaining security and integrity.
