Note

• This script is just an example, you should use better way of storing the key and password, like using environment variable or using a service like Hashicorp's Vault.
• It is recommended to use AES-GCM which is authenticated encryption mode and also encrypt in a streaming fashion.
• The salt variable is set to a fixed value, This is not recommended for actual use
