Secure Env Loader 🔐

A lightweight Go utility to securely fetch and load environment variables from an encrypted database, designed for backend services that require dynamic configuration without exposing secrets in code or .env files.

🌟 Features

• Secure storage of DB credentials and API keys in MongoDB (or any DB)
• Encrypted secret key-based access
• Auto-fetch and injects env variables during application start
• Works well with microservices or distributed systems
• Minimalistic and easy to integrate

📦 Technologies Used

• Go (Golang)
• MongoDB
• AES Encryption (CTR or ECB mode)
• dotenv (if .env fallback is needed)

🔐 Use Case

You can't store DB credentials directly in .env files or hardcode them.
Instead, store them in a DB collection in encrypted format and access them securely at runtime.

🧠 How It Works

1. On app start, pass a decryption key as an input flag or env variable.
2. The app connects to a base DB using minimal details.
3. It decrypts the secrets stored in a collection (like secrets_config) using the key.
4. The fetched values are injected into os.Environ() so that all parts of the app can use them like normal env variables.

🧪 Example

os.Getenv("DB_HOST") // returns 127.0.0.1 from secure loader
