Installation

To install the package, run the following command:

After installation, publish the migration files:

Then, run the migrations:

Configure your .env file to use Redis for queue management:

Finally, start the queue worker:

Configuration

RequirePin uses Redis to manage PIN confirmation queues efficiently. Ensure that your Redis server is properly configured and running.

Usage

Applying Middleware

To enforce PIN confirmation on specific routes, apply the require.pin middleware to those routes or route groups. For example:

Routes

The package provides the following routes:

API Routes:

• POST api/change/pin: Endpoint to change the user's PIN.
• POST api/pin/required/{uuid}: Endpoint to confirm the PIN for a specific request.

Web Routes:

• POST change/pin: Endpoint to change the user's PIN.
• POST pin/required/{uuid}: Endpoint to confirm the PIN for a specific request.
• GET change/pin: Page to display the form for changing the PIN.
• GET pin/required/{uuid?}: Page to display the form for PIN confirmation.

Note: To receive JSON responses, add the 'Accept: application/json' header to your requests.

Reserved Keys for Payload

The following keys are reserved for use within the payload:

• uuid - Unique identifier for the PIN request.
• pin - The PIN value submitted by the user.
• expires - Expiration time for the PIN request.
• signature - Timestamp indicating when the PIN was verified.
• return_payload
• pin_validation

Ensure these keys are not overridden when handling the payload.

To Display Return Payload Within Blade

To display the returned payload values within a Blade template, use:

You can customize this based on your application's needs.

Security Considerations

• PIN Policies: Ensure that your application enforces strong PIN policies, such as minimum length and complexity requirements.
• Rate Limiting: Implement rate limiting on PIN confirmation endpoints to prevent brute-force attacks.
• Secure Storage: Store PINs securely using appropriate hashing algorithms.
