I have a postscript file which has been created from secure or encrypted (opening restriction) pdf.

Now when i use distiller to convert this postscript file to pdf then distiller cannot produce a pdf file.

The log file contains following text:
This PostScript file was created from an encrypted PDF file.
Redistilling encrypted PDF is not permitted.
%%[ Flushing: rest of job (to end-of-file) will be ignored ]%%
%%[ Warning: PostScript error. No PDF file produced. ] %%

1) Is there a way to convert this postscript file into pdf ?
   I have a limitation that i cannot remove security from secure pdf.

2) Do distiller provide any settings which can be changed to convert
   this kind of ps(from secure pdf) to pdf.

3) Can we provide password to distiller during process of conversion to
   pdf.

4) If above methods do not work then is there a way we can
   programatically using Distiller Api's for conversion to pdf.
   Like methods 'FileToPdf' etc.

Thanks in advance.

The only way to do what you want to do with any programs and/or tools from Adobe is to unencrypt the PDF file first in Acrobat and saving the file without security.

To answer your specific questions:

(1) No, there is no way to "convert the PostScript file to PDF" with any Adobe program if the PDF file from which printing was performed was protected.

(2) No, Distiller has no such settings which, if they existed, would make PDF protection totally useless.

(3) No.

(4) No, not with any Adobe products!

Thanks Dov

I am ok, even if security is not removed from final pdf obtained from conversion of ps to pdf.

My workflow is such that pdf is converted into postscript, some operations are performed on ps and then converted back to pdf.
I do not want that security should be removed from final pdf obtained.

I guess in above scenario i am not breaking the security.

That still does not change the fact that by design Adobe Acrobat and Adobe Reader generate PostScript such that Distiller will absolutely not process such PostScript. The security must first be removed in Acrobat.
