Hi... I know this discussion has more than 2 years...
@gkArvindr you must provide the PDF password using the -SPDFPassword parameter.
gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -SPDFPassword=THE_PASSWORD -sOutputFile=unencrypted.pdf -c .setpdfwrite -f 2017-06-13-11-55-56-188_14972345156188_XXXPT6345X_ITRV.pdf

I've updated the original gist now - cheers @denysvega
