You can password protect and restrict a PDF inside the payload of InterFormNG2, that is later saved. The PDF should normally first be created with the component: Create PDF document. When you open a protected PDF file, you will be prompted for a password.

To do this, you need to use the advanced utilities workflow component: PDF Protect/restrict. From version 4.2.0 AES-128 encryption is used (previously it was 40-bit RC4).

Prerequisites:

1. In order to password protect a PDF, you need a license code for InterFormNG2, that includes the Advanced PDF module.
2. After adding the passwords you need to output the PDF file e.g. with the To filesystem workflow component.

The PDF Protect/restrict component has these parameters: 

1. User password
   The user password for the PDF file. If you use this password, the PDF actions might be restricted as specified below.
2. Owner password
   The owner password ignores any restrictions setup for the PDF file.
3. Restrict copy
   When this option you can prevent the user from copying text from the PDF file.
4. Restrict edit
   With this you can prevent the user from editing the PDF file.
5. Restrict print
   Prevents the user from printing the PDF file.
6. Encryption algorithm
   The algorithm used to encrypt the PDF file. Choose AES-256 for the strongest encryption, or AES-128 if the PDF needs to be opened in older PDF viewers that do not support AES-256. This parameter is available from version 4.4.0.

All of the restrictions can be set to a fixed value enabled or disabled on by clicking this icon on the left:

- but you can also set a dynamic value, if you click this icon on the right:

Then you can set a dynamic Xpath expression to set a dynamic value of either yes or no.
