The Advanced PDF module includes these options:

1. Append a PDF i.e. merge two PDF files together.
2. Encrypt, password protect and restrict the use of output PDF files. With this you can create a password protected PDF file and enable/disable functions depending on if the master or user password is used for opening the PDF file.
3. Add a digital signature to output PDF files. With you can build a legally binding PDF file/document with a digital signature to ensure who created the PDF file, when it was created and ensure that the PDF file is unchanged since the PDF file was signed.
4. Create PDF files with form fields. With this you can define multiple entry form fields in a PDF file. The entered values can later be extracted from the PDF.
5. Embed any file in a PDF file. You can use this e.g. to include PDF files with the referenced invoices, when you generate a reminder.
