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.

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. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Megurio SSL Manager” is open source software.
