## 外掛說明

Content Sentinel is a powerful WordPress plugin that enables secure, time-limited
access to files stored in AWS S3 or S3-compatible storage providers (like Wasabi,
DigitalOcean Spaces, and Backblaze B2). Perfect for protecting premium content, 
course materials, digital products, and media files.

#### Key Features

 * **Secure File Delivery**: Generate presigned URLs that expire automatically, 
   ensuring your files remain protected
 * **S3 Browser**: Browse your S3 bucket directly from WordPress admin (Pro feature)
 * **S3 Compatible**: Works with AWS S3, Wasabi, DigitalOcean Spaces, Backblaze 
   B2, and other S3-compatible providers
 * **Clean URLs**: Use shortcodes to generate clean, user-friendly download links
   instead of long presigned URLs
 * **No AWS SDK Required**: Pure PHP implementation – no external dependencies
 * **Easy Setup**: One-click AWS CloudFormation setup or manual configuration
 * **Flexible Delivery Modes**: Force download or stream/play in browser (Pro feature)
 * **Custom Denial Messages**: Customize access denied messages (Pro feature)

#### How It Works

 1. **Configure Your Storage**: Connect to your AWS S3 bucket or S3-compatible provider
 2. **Generate Secure Links**: Use the shortcode `[content_sentinel_url key="/path/
    to/file.mp4"]` to create secure download links
 3. **Automatic Expiration**: Links expire after a set time (default: 10 minutes, configurable)
 4. **Protect Your Content**: Files are never directly accessible – users must go through
    WordPress authentication

#### Use Cases

 * **Course Platforms**: Deliver course videos and materials securely
 * **Digital Products**: Protect downloadable products and resources
 * **Membership Sites**: Control access to premium content
 * **Media Libraries**: Securely serve large video/audio files
 * **Document Sharing**: Share sensitive documents with time-limited access

#### Pro Features (Content Sentinel Pro)

Upgrade to Content Sentinel Pro for advanced features:

 * **Access Control**: Integrate with MemberPress, Paid Memberships Pro, or WordPress
   Roles
 * **Download Limiting**: Set per-user and per-IP download limits
 * **Download Logging**: Track all download attempts with detailed logs
 * **Custom Expiration**: Override default expiration times per file
 * **S3 Browser**: Browse, navigate, and manage files directly in WordPress
 * **Enhanced Video Player**: Professional video player with speed controls and 
   Picture-in-Picture
 * **File Access Rules**: Set granular permissions for individual files
 * **Export/Import Rules**: Backup and restore your access control settings
 * **Coming Soon – Google Cloud Services – S3.
 * **Coming Soon – Visual Controls for the Enhanced Video Player.

#### Technical Details

 * **Pure PHP**: No external dependencies or AWS SDK required
 * **AWS Signature Version 4**: Industry-standard security for S3 requests
 * **WordPress Native**: Uses WordPress APIs and follows WordPress coding standards
 * **Performance Optimized**: Caching and efficient URL generation
 * **Security First**: Input sanitization, nonce verification, and capability checks

## 常見問題集

### Do I need an AWS account?

No! Content Sentinel works with AWS S3, but also supports S3-compatible providers
like Wasabi, DigitalOcean Spaces, and Backblaze B2. You can use any S3-compatible
storage service.

### Is the AWS SDK required?

No! Content Sentinel uses pure PHP to generate AWS Signature Version 4 requests.
No external dependencies are required.

### How secure are presigned URLs?

Presigned URLs use AWS Signature Version 4, the same security standard used by AWS
SDKs. URLs expire after a set time (default: 10 minutes), and each URL is cryptographically
signed.

### Can I use this with S3-compatible providers?

Yes! Content Sentinel supports any S3-compatible storage provider. Simply select“
S3 Compatible” and enter your provider’s endpoint URL.

### What permissions does my IAM user need?

Your IAM user needs:
 * `s3:GetObject` – To download files * `s3:ListBucket` – To
browse files (Pro feature)

You can restrict access to specific buckets or paths for additional security.

### How do I generate download links?

Use the shortcode: `[content_sentinel_url key="/path/to/file.mp4"]`

Or use the Pro version’s S3 Browser to copy links directly.

### Can I customize the expiration time?

Yes! The default expiration is 10 minutes, but you can change it in settings (up
to 7 days, which is AWS’s maximum). Pro users can set custom expiration times per
file.

### What happens if a link expires?

Expired links return an error. Users will need to request a new link. This ensures
your content remains protected.

### Do I need the Pro version?

The free version provides secure file delivery with presigned URLs. Upgrade to Pro
for access control using wordpress roles/memberpress/paid membership pro, download
limiting, file logging, and the S3 Browser Control interface.

### Is my data secure?

Yes! Content Sentinel follows WordPress security best practices:
 * All inputs are
sanitized * Nonces verify form submissions * Capability checks restrict access *
No sensitive data is logged * Files are never directly accessible
