The scenario is,
i have created a pdf file for my personal document, and then to make it safe i put a password so anyone else cant read the file except myself.
After a month later, I’ve forgot the password but i want to read the file as soon as possible.
here it comes, pdfcrack! ( also available on win32 )
Mission: recover the password
target: piju.pdf’s password
weapon: pdfcrack http://pdfcrack.sourceforge.net/
estimation time: depends on the length of the password
situation reports: no text, just photos
status: password recovered, mission accomplished, all units please stand down 🙂
