Thanks. I was able to achieve the functionality using the PDFBox library which ships with PRPC. Below is the java step to add after HTMLToPDF step. 

 

Note-> Make sure we are setting the Local.PDFDocument = Param.PDFDocument before calling this step. After the step is completed we need to again set Param.PDFDocument=Local.PDFDocument. 

The username and password local variables also need to be set. If password functionality is not required we can leave that blank while calling StandardProtectionPolicy Constructor. 

Thanks.

Pega has PDFUtils interface which is a wrapper on pd4ml.jar 

The option is not supported by pega OOTB and there is no way to set and do it.

However, while researching on pd4ml.jar, i could see this is possible.

http://pd4ml.com/reference.htm

...

String password = "empty";

boolean strongEncryption = true;

int permissions = PD4Constants.AllowPrint | PD4Constants.AllowCopy;

 

pd4ml.setPermissions( password, permissions, strongEncryption );

...

I assume we have pd4ml jar already present, you could achieve it by using java step in activity.

Hope this helps.
