Web Server Configuration

Apache (.htaccess)

Encrypt CMS requires the Apache mod_rewrite module enabled. The core archive includes a production .htaccess file handling URL rewrites to index.php:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /

    # Prevent direct access to hidden files (.env, .git)
    RewriteRule ^\.(?!well-known/) - [F,L]

    # Deliver existing static files directly
    RewriteCond %{REQUEST_FILENAME} -f [OR]
    RewriteCond %{REQUEST_FILENAME} -d
    RewriteRule ^ - [L]

    # Route all other requests through Front Controller
    RewriteRule ^ index.php [L]
</IfModule>

Nginx

If running Nginx, configure your server block location as follows:

location / {
    try_files $uri $uri/ /index.php?$query_string;
}

location ~ \.php$ {
    fastcgi_pass unix:/var/run/php/php8.2-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
    include fastcgi_params;
}

# Block protected storage and config directories
location ~ ^/(config|storage/framework|storage/logs)/ {
    deny all;
    return 404;
}
