I have an encrypted pdf, and I am aware of the password, and I would like to use the Ghostscript to make them unencrypted, so they don't require any password to be opened.
I tried using the following, But it seems I'm doing something wrong
gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=OUTPUT.pdf -c .setpdfwrite -f -sUserPassword=mypassword encrypted.pdf
If you have a pdf that is encrypted and you know the password you can decrypt the pdf as follows
gs -dNOPAUSE -dBATCH -q -sDEVICE=pdfwrite -sPDFPassword=password -sOutputFile=output2.pdf -f input.pdf
Now let me tell you about each option being used
-sDEVICE: its a device, use man gs to learn more-dNOPAUSE: Disables the prompt and pause at the end of each page. This may be desirable for applications where another program is driving Ghostscript.-q: do things quietly, no logs on screen-sPDFPassword: Its the password-dBATCH: I think it is for quitting the gsLike every Linux Program, the Documentation (man pages) is written very poorly and doesn't have a lot of information.
