"""
Encrypted secrets management with master password protection.

This module provides secure storage for sensitive configuration like API keys,
using Argon2id for password-based key derivation and Fernet (AES-256) for encryption.

Basic usage:
    from secrets_manager import SecretsStore

    # First time setup
    store = SecretsStore()
    store.initialize("my-master-password")
    store.set("ANTHROPIC_API_KEY", "sk-ant-...")

    # Later usage
    store = SecretsStore()
    store.unlock("my-master-password")
    api_key = store.get("ANTHROPIC_API_KEY")

Command-line interface:
    python -m secrets_manager.cli init
    python -m secrets_manager.cli set KEY VALUE
    python -m secrets_manager.cli get KEY
    python -m secrets_manager.cli list
    python -m secrets_manager.cli change-password
