### Presentation

The PDFSecure plugin allow you to protect PDF files by requesting a password to access its content
The plugin uses the same features that *Secure-ebook* platform was providing.
PDF password protection will be based on the serial code, which will become the key for the file.

The plugin do not need any configuration, just a special filepath to let the plugin override the download.

**Initiate the plugin**
For an HikaShop product linked to an HikaSerial pack, upload a PDF file.
Edit the HikaShop product file and change its *Filename* by adding the special code as prefix:

```
#hikaserial:pdfsecure:
```

If your PDF file is *my\_pdf\_file.pdf* it will become *\#hikaserial:pdfsecure:my\_pdf\_file.pdf*.

The PDFSecure plugin will detect that special prefix, open the PDF file and apply the password protection thanks to the serial related to the product in the customer order.

### Legacy plugin (Secure-ebook)

The Secure-ebook plugin do not work anymore since the platform has ceased its activities on March 6th, 2017.
