# Owlen Credentials

Secure credential storage for the Owlen AI agent.

## Overview
This crate provides a cross-platform abstraction for storing sensitive data like API keys and OAuth tokens. It prioritizes system-native keychains and falls back to encrypted file storage when necessary.

## Features
- **Keyring Support:** Native integration with macOS Keychain, Windows Credential Manager, and Linux Secret Service.
- **Encrypted Fallback:** AES-encrypted JSON file storage (`~/.config/owlen/credentials.json`).
- **Credential Helpers:** Support for external tools like `op` (1Password) or `bw` (Bitwarden).
- **Security First:** Implements proper zeroing of sensitive memory where possible.

## Components
- `CredentialManager`: Primary interface for store/retrieve operations.
- `KeyringStore`: System-native backend.
- `FileStore`: Encrypted local file backend.
- `HelperManager`: Integration with external credential CLI tools.
