# API Key Manager Overview

The **API Key Manager** is a critical module designed to securely manage and control access to system data via API keys. It provides developers with a centralized platform to generate, distribute, monitor, and revoke API keys, ensuring secure and controlled access to sensitive resources.

## Purpose

The primary purpose of the API Key Manager is to:

- Centralize the management of API keys across the system.
- Ensure secure generation, distribution, and revocation of API keys.
- Provide auditing capabilities to track key usage and access patterns.
- Facilitate compliance with security policies and best practices for API key management.

## Benefits

The API Key Manager offers several benefits:

- **Enhanced Security**: Safely store and manage API keys in a secure manner, reducing the risk of unauthorized access or data breaches.
- **Simplified Integration**: Provide developers with easy-to-use interfaces to generate and integrate API keys into their applications.
- **Audit and Compliance**: Track API key usage and access patterns for compliance reporting and auditing purposes.
- **Scalability**: Support large-scale systems by managing thousands of API keys efficiently.
- **Fine-grained Access Control**: Define specific permissions and restrictions for each API key, ensuring that only authorized users and services can access sensitive data.

## Usage Scenarios

The API Key Manager is particularly useful in the following scenarios:

### 1. Third-party Integrations
- Developers integrating third-party services (e.g., payment gateways, analytics tools) can use the API Key Manager to generate secure API keys for these services.
- This ensures that sensitive credentials are not hard-coded into applications and are managed centrally.

### 2. Multi-Environment Management
- Managing multiple environments (development, staging, production) becomes easier with the API Key Manager. Developers can create environment-specific API keys and manage them seamlessly.

### 3. Auditing and Security Monitoring
- Organizations requiring compliance with security standards (e.g., GDPR, HIPAA) can use the API Key Manager to audit API key usage, track access patterns, and detect suspicious activities.

### 4. Team Collaboration
- Development teams can collaborate on API key management by assigning roles and permissions through the module. This ensures that only authorized team members can generate or revoke keys.

### 5. Key Rotation and Revocation
- The module simplifies the process of rotating API keys periodically to enhance security. Developers can easily revoke keys if they are compromised or no longer needed.

## Conclusion

The API Key Manager is an essential tool for developers seeking to manage API keys securely, efficiently, and compliantly. By centralizing API key management, it reduces risk, enhances security, and simplifies integration efforts across the development lifecycle.

Secure API Key Storage

The module securely stores API keys in a encrypted format, ensuring that sensitive information is protected from unauthorized access. This feature provides peace of mind for developers by safeguarding credentials against potential breaches.

Role-Based Access Control (RBAC)

API Key Manager implements RBAC to control who can view, modify, or delete API keys. Developers with appropriate permissions can manage keys, while others are restricted, enhancing security and compliance with organizational policies.

Audit Logging

Every action taken on API keys is logged, including creation, modification, deletion, and access attempts. This feature provides transparency and helps in tracking unauthorized activities, ensuring accountability for all key-related operations.

Automated Key Rotation

The module supports automated rotation of API keys at predefined intervals. This minimizes the risk of long-term exposure and ensures that credentials remain secure over time without requiring manual intervention.

Key Revocation

Developers can revoke API keys immediately if they are compromised or no longer needed. This feature provides an added layer of security by allowing quick removal of unauthorized access points.

Integration Capabilities

The module offers APIs for seamless integration with other systems and tools. Developers can programmatically generate, retrieve, update, and delete API keys, enabling efficient automation of key management processes.

Reporting & Analytics

API Key Manager generates reports on key usage, expiration dates, and access patterns. These insights help developers optimize key management strategies, identify potential security risks, and ensure compliance with internal policies.

Programmatic Key Generation

The module provides a robust API for generating new API keys programmatically. This feature simplifies integration with external systems and automates the process of onboarding new services or applications.

    api_key: str
    expires_in: int

# Mock database of users (for demonstration purposes)
users_db = {
    "user@example.com": {"password": "testpass", "disabled": False},
}

async def get_current_user(email: str, password: str):
    if email not in users_db:
        raise HTTPException(status_code=400, detail="Incorrect email or password")
    
    user = users_db[email]
    if user.get("password") != password:
        raise HTTPException(status_code=400, detail="Incorrect email or password")
    
    return {"email": email}

@router.post("/token", response_model=Token)
async def login(email: str, password: str):
    try:
        payload = await get_current_user(email, password)
        
        # Generate API key (simulated for demonstration)
        import random
        api_key = "sk-" + "".join(random.choices("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789", k=40))
        
        # Generate JWT token (simulated)
        from datetime import datetime, timedelta
        expiration = datetime.now() + timedelta(minutes=30)
        
        return {
            "access_token": f"Bearer {api_key}",
            "token_type": "bearer",
            "api_key": api_key,

    try {
      const response = await axios.post(`${endpoint}/token`, {
        email,
        password
      });
      
      console.log("API Key:", response.data.api_key);
    } catch (err) {
      setError(err.message || "Failed to generate API key");
    } finally {
      setLoading(false);
    }
  };

  return (
    <div className="container">
