hacking: security in practice
Is there a way to speed up the decryption of PDF if you have a page?

Hi,

I have a PDF that is encrypted with $pdf$56256-10281*16. It would take years to brute force it (the password is 10-16 long I guess) with hashcat. If I have another PDF with the same first page, is there a way to hack it faster? Is there a way to create a decryption "key" if I know the first page?

Or is there an easier/faster way than brute force? I read about PDFex, but I didn't found a way how to do it or if it does still work.
