## 説明

Megurio SSL Manager allows you to issue and manage Let’s Encrypt SSL/TLS certificates
directly from your WordPress admin panel.

**Features:**

 * Issue SSL certificates via ACME v2 protocol (no external libraries)
 * Multi-domain (SAN) certificates — up to 100 domains per certificate
 * Wildcard domain support via DNS-01 challenge
 * Choose HTTP-01 file verification or DNS-01 TXT record verification when creating
   each certificate order
 * Renewals keep using the verification method selected for the original order
 * Reuse pending verification challenges while they are still valid; failed validation
   starts a fresh challenge flow
 * Clean admin workflow with a modal form for adding certificate orders
 * Automatic renewal reminder when certificate expires within 30 days
 * Download certificate files as a ZIP archive (fullchain, cert, chain, private 
   key)
 * Settings page for configuring the email address used for Let’s Encrypt account
   registration
 * Issued certificate data is stored in the WordPress database, not in the plugin
   directory

### External services

This plugin connects to the Let’s Encrypt ACME API to register an ACME account, 
request certificate orders, validate domain ownership, and issue SSL/TLS certificates.

When you create or verify a certificate order, the plugin sends the configured account
email address, the requested domain names, ACME challenge responses, and ACME account/
order data to Let’s Encrypt. Let’s Encrypt may also perform HTTP or DNS validation
requests for the requested domain names.

This service is provided by Internet Security Research Group (ISRG) / Let’s Encrypt.

## インストール

 1. Upload the `megurio-ssl-manager` folder to the `/wp-content/plugins/` directory.
 2. Activate the plugin through the **Plugins** menu in WordPress.
 3. Go to **Megurio SSL Manager** > **Certificate Settings** and enter your email address.
 4. Go to **Megurio SSL Manager** to manage and issue certificates.

## FAQ

### Does this plugin require any external libraries?

No. The ACME v2 client is implemented using only PHP’s built-in `openssl_*` functions
and the WordPress HTTP API.

### What verification methods are supported?

Both HTTP-01 (file verification) and DNS-01 (TXT record) are supported. Choose the
verification method when creating the certificate order. Renewals use the same method.
Wildcard domains (e.g. `*.example.com`) always require DNS-01.

### Can I reuse a verification challenge?

Only pending challenges can be reused. If validation fails because the challenge
is invalid or unreachable, the plugin clears the pending challenge so the next File
Verify or DNS Verify action gets a fresh challenge from Let’s Encrypt.

### How many domains can I add to one certificate?

Up to 100 domains per certificate (Let’s Encrypt limit).

### Where are the certificate files stored?

Issued certificate data, including the private key, is stored in the WordPress database
as part of this plugin’s saved certificate records. The plugin generates a temporary
ZIP file only when you click Download, then removes that temporary file after sending
it to your browser.

### How do I renew a certificate?

A **Renew** button appears automatically when the certificate has 30 or fewer days
remaining before expiry. The renewal button uses the verification method selected
when the certificate order was created.
