# PDF Password Protection Page
Here's a complete JavaScript implementation for a PDF password protection page similar to the one on ilovepdf.com. This code can be pasted directly into your Blogger HTML editor:
```html
<div class="pdf-protect-container">
<div class="pdf-protect-header">

## Features Implemented:
1. **File Upload Interface**:
- Drag and drop functionality
- File selection button
- PDF validation (file type and size)
2. **Password Protection Settings**:
- Password input with confirmation
- Password strength meter
- Permission controls (printing, copying, modifications)
3. **Result Display**:
- Success message with download button
- Error handling with appropriate messages
- Option to process another file
4. **Responsive Design**:
- Works on mobile and desktop
- Clean, modern UI similar to ilovepdf.com
## Important Notes:
1. This is a **client-side implementation only**. In a real-world scenario, you would need server-side processing to actually password-protect PDFs.
2. The download button currently provides the original file (for demonstration). In a real implementation, you would:
- Upload the PDF to a server
- Process it with a PDF library (like PDF-lib, iText, etc.)
- Return the protected PDF for download
3. For a complete solution, you would need to:
- Set up a backend service to handle PDF processing
- Implement proper error handling for large files or processing failures
- Add user authentication if needed
You can paste this entire code block directly into your Blogger HTML editor to add this functionality to your site.
