## Description

Create messages with expiration/limited views via the **CryptNote.pro** API without
leaving WordPress.

 * Admin form to generate `share_url` and token via API.
 * Option to replace all sent emails (`wp_mail`) with a secure link (attachments
   are removed).
 * Customizable placeholders in the email body: `{share_url}`, `{token}`, `{max_views}`,`{
   expire_minutes}`.
 * Support for optional password, expiration in minutes, and Markdown/HTML flags.
 * Configurable endpoint (default `https://cryptnote.pro/api/v1`) and optional `
   X-API-Key` header.

### Privacy

This plugin uses the external **CryptNote** service to generate and host the secure
link and token. When creating a link, the protected content and metadata (views,
expiration, optional password) are sent to `https://cryptnote.pro/api/v1`. See the
service’s privacy policy at https://cryptnote.pro/privacy.php?lang=en.

## Installation

 1. Upload the `plugin-wordpress` folder to `wp-content/plugins/` or compress it as`.
    zip` and upload via the Plugins panel.
 2. Activate **CryptNote Secure Links**.
 3. In the sidebar menu, open **CryptNote** and configure the base endpoint, API key(
    if used), and defaults.
 4. (Optional) Check “Enable secure links for all emails” to protect all `wp_mail` 
    content.

## FAQ

### Do I need an API key?

Only if your CryptNote instance requires it. The plugin sends it in the `X-API-Key`
header when provided.

### Which endpoints are used?

POST {api_base}/create.php to generate the link. The default is `https://cryptnote.
pro/api/v1`.

### What happens to email attachments?

They are removed when email protection is active, to prevent data leakage outside
the secure link.

### Can I use Markdown or HTML?

Yes. Enable the desired format in the defaults or per submission. The plugin sends`
is_markdown=true` or `is_html=true`.
