## Описание

2IZI SmartCaptcha for Yandex adds server-validated Yandex SmartCaptcha protection
to common WordPress forms. Developed and maintained by 2IZI. Project page: https://
2izi.ru/en/projects/smartcaptcha

Features:
 * WordPress login, registration and lost-password protection. * Optional
WordPress comments protection. * WooCommerce login, registration and lost-password
protection. * Optional WooCommerce classic checkout and product-review protection.*
Optional Contact Form 7 integration. * Server-side token verification. * Per-form
enable/disable switches. * Configurable fail-closed behavior. * Translation-ready
using the standard WordPress.org translation system. * Runtime translations are 
distributed through translate.wordpress.org language packs.

#### External service

This plugin relies on Yandex SmartCaptcha, a third-party service operated through
Yandex Cloud. The SmartCaptcha JavaScript is loaded from `https://smartcaptcha.cloud.
yandex.ru/captcha.js` on pages where a protected CAPTCHA widget is rendered. When
a protected form is submitted, the CAPTCHA token and, when available, the visitor
IP address are sent server-side to `https://smartcaptcha.cloud.yandex.ru/validate`
together with the site owner’s private server key to verify the request.

A Yandex Cloud account and a configured SmartCaptcha are required. Review the service
documentation and applicable legal terms before enabling the plugin:
 * Service 
documentation: https://yandex.cloud/en/docs/smartcaptcha/ * Yandex Cloud Terms of
Use: https://yandex.com/legal/cloud_terms_smartcaptcha/ * Yandex Privacy Policy:
https://yandex.com/legal/confidential/

## Установка

 1. Upload the plugin ZIP in Plugins > Add New > Upload Plugin, or install it from 
    WordPress.org when available.
 2. Activate the plugin.
 3. Create a SmartCaptcha in Yandex Cloud: https://yandex.cloud/en/services/smartcaptcha
 4. Copy its Client key and Server key. Key instructions: https://yandex.cloud/en/docs/
    smartcaptcha/operations/get-keys
 5. Open Settings > 2IZI SmartCaptcha.
 6. Save both keys and enable the forms you want to protect. WooCommerce checkout protection
    currently targets the classic checkout flow; test it before production use.
 7. Test login and other protected flows in a separate browser/private window before
    logging out of the administrator session.

## Часто задаваемые вопросы

### Is this an official Yandex plugin?

No. This is an independent plugin by 2IZI that integrates with the Yandex SmartCaptcha
service.

### Does the server key appear in page HTML?

No. The server key is used only in server-side verification requests. The client
key is public and is included in the widget markup as required by SmartCaptcha.

### What happens if Yandex SmartCaptcha cannot be reached?

By default, protected submissions are blocked (fail closed). Administrators can 
change this behavior in settings, but fail-closed mode is recommended for security-
sensitive forms.

## Журнал изменений

#### 1.0.12

 * Added direct links in plugin settings to create Yandex SmartCaptcha and obtain
   Client/Server keys.
 * Added locale-aware Yandex Cloud links for Russian and other WordPress admin locales.
 * Removed Russian text from the source English readme so translations are handled
   through translate.wordpress.org.

#### 1.0.11

 * Strengthened plugin-specific prefixes for PHP declarations, stored options, script
   handles and JavaScript globals.
 * Updated the Yandex SmartCaptcha terms URL.
 * Removed bundled runtime translation files in preparation for WordPress.org language
   packs.

#### 1.0.10

 * Added the dedicated 2IZI SmartCaptcha project page as the Plugin URI.
 * Added locale-aware project links in plugin settings for Russian, English, Japanese,
   Chinese and Italian.

#### 1.0.9

 * Removed the Plugin URI header to keep it distinct from the 2IZI Author URI for
   WordPress.org submission.

#### 1.0.8

 * Prepared for WordPress.org Plugin Check: removed the unnecessary manual text-
   domain loader.
 * Documented intentional CAPTCHA token POST handling for host forms.
 * Added an explicit version to the Yandex SmartCaptcha script enqueue.

#### 1.0.6

 * Fixed the Russian translation of the live SmartCaptcha preview description in
   plugin settings.
 * Synchronized plugin version metadata for the WordPress.org submission build.

#### 1.0.5

 * Added a small, non-promotional developer information block to the plugin settings
   page.
 * Added consistent 2IZI developer attribution and website information without changing
   CAPTCHA behavior.
 * Prepared the package as a release candidate for WordPress.org submission.

#### 1.0.4

 * Fixed automatic SmartCaptcha language detection.
 * SmartCaptcha now follows the current WordPress request locale, including the 
   language selector on wp-login.php.
 * Manual SmartCaptcha language selection still overrides automatic detection.
 * Unsupported WordPress locales fall back to English for the SmartCaptcha widget.

#### 1.0.3

 * Replaced the separate connection-test button with an automatic live SmartCaptcha
   preview after the Client and Server keys are saved.
 * The settings preview uses the real Yandex SmartCaptcha widget and the saved widget
   language.

#### 1.0.2

 * Improved SmartCaptcha placement and spacing on WordPress forms.
 * Added responsive frontend styles for narrow and mobile layouts.
 * Submit controls are disabled until SmartCaptcha returns a valid token.
 * Submit controls are disabled again when the token expires or the widget reports
   an error.
 * Added accessible, localized frontend status messages.
 * Switched the frontend widget integration to the documented advanced SmartCaptcha
   API for reliable event handling.

#### 1.0.1

 * Rebuilt the settings page to use native WordPress admin UI patterns.
 * Added full Russian translation and standard WordPress gettext localization support.
 * The plugin interface now follows the WordPress admin locale.
 * Improved localized connection-test messages and mobile settings layout.

#### 1.0.0

 * Initial release.
 * WordPress core forms protection.
 * WooCommerce integration.
 * Contact Form 7 integration.
 * Server-side Yandex SmartCaptcha validation.
 * Privacy-policy suggestion and external-service disclosure.
