How to send the token key from the user-side frontend, and how to handle it from the backend? Additionally, which method should be used to ensure a secure token key approach in CodeIgniter?
How to send a token with every request using HTTP headers?
Which encryption is used to secure the token key?
To implement token-based authentication in CodeIgniter, you can follow these steps:
Generate Token:
When a user logs in, generate a unique token for that user.
This token should be securely generated using a strong hashing algorithm and should have a limited lifespan to enhance security.
Send Token to Client:
After generating the token, send it back to the client (frontend) as part of the login response.
Typically, this token is sent in the response body or headers, depending on your application's requirements.
In JavaScript frameworks like Angular or React, you would typically store this token in local storage or session storage.
Send Token with Every Request:
On the frontend, ensure that the token is sent with every subsequent request to the backend.
You can achieve this by setting the token in the headers of your HTTP requests.
Validate Token on the Backend:
In your CodeIgniter backend, create a middleware or interceptor to validate the token sent with each request.
This middleware should check the validity and expiration of the token.
If the token is invalid or expired, deny access to the requested resource.
Renew Token (Optional):
Optionally, you can implement a mechanism to renew tokens to avoid frequent logins.
This can be done by issuing a new token with a refreshed expiration time upon successful token validation.
Logging Out:
To log out a user, simply invalidate or delete the token from both the client and the backend.
On the client-side, remove the token from local storage or session storage.
On the server-side, you might have to maintain a blacklist of invalidated tokens.

Which encryption is used to secure the token key?
In CodeIgniter, you can handle token-based authentication using libraries like Firebase JWT, JWT, or implement it manually using PHP's native JWT library. These libraries provide methods for token generation, validation, and expiration handling. Choose a library that best fits your project requirements and integrate it into your CodeIgniter application for secure token-based authentication.
