I have to extract a PDF book from a PW protected RAR file.
I successfully extracted the compressed file with 7-Zip, but when I try to open the decompressed PDF book I am asked for a PW. There are a number of applications to retrieve the PW, but in order to better target my search I'd like to know where should I look for the PW: in the RAR archive or in the extracted PDF file? Some password retrieval applications are designed for PDF files and others for RAR/ZIP archives. Where should I look for?
