Does PD4ML provide PDF content protection?

#26188

PD4ML allows you to secure your PDF documents with 40-bit/128-bit encryption. You can disable printing, modifications or extracting of text content, you can lock your PDF with a password.

PD4ML API call example:

htmlConverter.setPermissions( "empty",
PD4Constants.AllowAnnotate | PD4Constants.AllowAssembly |
PD4Constants.AllowContentExtraction | PD4Constants.AllowCopy |
PD4Constants.AllowFillingForms | PD4Constants.AllowModify |
PD4Constants.AllowPrint, true);

The constants in the sample above represent integer values. If you use PD4ML JSP taglib you would need to pass the sum of the permission constant values.

<pd4ml:permissions password="empty"
rights="2056" strongEncryption="true">

The values correspond to the values defined in Adobe PDF specification and may be also taken from there.
