## Description

BASIC License Key Seller turns downloadable WooCommerce products into licensed WordPress
plugin sales.

 * Automatically generates a unique license key when an order is paid.
 * Supports one-site, three-site, and unlimited activation limits.
 * Provides HTTPS REST endpoints for activation, validation, and deactivation.
 * Adds license keys to customer order emails.
 * Adds a Licenses section under WooCommerce My Account.
 * Protects downloads with WooCommerce permissions and current license status.
 * Encrypts license keys at rest and stores lookup credentials as keyed hashes.
 * Works with Stripe, PayPal, and other gateways that mark WooCommerce orders paid.

The free plugin does not require registration, a Blockrush account, or an external
service. An optional, separately distributed Pro plugin adds subscription lifecycle
handling, reporting, and administrative license controls. Pro implementation is 
not included in this WordPress.org package.

### Privacy

This plugin does not contact Blockrush or any other external service. It stores 
license keys, customer user IDs and email addresses, WooCommerce order and product
IDs, license status and expiry, and activated site URLs in the site’s WordPress 
database. Uninstalling retains this data by default to prevent accidental loss; 
the included documentation explains the opt-in deletion constant. Payment processing
remains the responsibility of WooCommerce and the selected gateway.

### Security

License keys are generated from cryptographically secure random data and encrypted
at rest using Sodium or OpenSSL authenticated encryption. A dedicated random plugin
secret is generated during activation, stored as a non-autoloaded option, and used
to derive separate encryption, lookup, installation, and rate-limiting keys. Advanced
installations may define a stable `BLKS_CRYPTO_SECRET` value of at least 32 unpredictable
characters in `wp-config.php` before activation. API calls require HTTPS and are
rate limited. Customer and administrator actions use WordPress permissions and nonces.

### Support

Use the support forum on this plugin’s WordPress.org page. Do not post license keys
or customer information publicly.

## Installation

 1. Install and activate WooCommerce.
 2. Upload and activate BASIC License Key Seller.
 3. Edit a WooCommerce product.
 4. Under Product Data  General, enable Issue License Keys and choose the activation
    limit.
 5. Mark the product Downloadable and attach the customer plugin ZIP.

    management.

## FAQ

### Does the free plugin require a license key?

No. The WordPress.org edition is fully functional and does not contact Blockrush.

### Does it work with Stripe?

Yes. It works with Stripe and other WooCommerce gateways when they correctly mark
an order paid or completed. This plugin does not store payment credentials.

### What is included in Pro?

Pro is a separately installed commercial plugin offering WooCommerce Subscriptions
lifecycle handling, dashboard statistics, and administrator suspension and reactivation
controls. None of that implementation is included in this WordPress.org package.

### Does the free edition manage subscription renewals?

No. Subscription lifecycle handling is a Pro feature. The free edition is intended
for one-time WooCommerce purchases.

### Where are the API endpoints?

Send JSON POST requests to `/wp-json/lks/v1/activate`, `/wp-json/lks/v1/validate`,
and `/wp-json/lks/v1/deactivate`. HTTPS is required.
