okay so i had to buy this ebook.....it is in .pdf format with at least a ebx 40bit encryption on it...
and i have ran out of ideas of how to gain access to it...because i believe that this ebook is mine and just like if i bought a physical book should be able to keep it safe....well it comes with some strings attached...i cannot back it up or anything....so if my hard drive fails in my laptop i am done....no more ebook and the company will only allow me one hdd to download it to....and they won't give me the password that they have for the ebook i own....
so i am sick of dealing with these ppl i believe since i paid money for the stupid book i should be able to keep it safe and back it up and use it on any of my computers....
so this is a long story short....
i have used pdfcrack which told me that it cannot deal with the EBX encryption...and also tried to use pdf2ps to switch it to a .ps format then back to .pdf which would get rid of the password but it didn't work....
any help would be greatly appreciated....
i am using debian 5.0 "lenny"...
and i really want to do this because this goes against all i believe in.....the stupid company should atleast allow me to have the password or something....so i am left with hopefully getting a brute force attack on it....and just save the already tried passwords to a file so that way i can restart later and not have to leave my pc on all the time....
i am thinking it has the set of the alphabet a-z, A-Z, 0-9, and some ascii symbols, {}, [], -, _ , %, #
