In case youre not familiar with the PDF password protection then let me tell you that there are basically two s of PDF passwords 3 owner password and user password. If a pdf is protected with user password then you can open that pdf without entering the right password. Owner password restricts some basic functions like printing editing copying and images and so on. If your PDF document is protected with the owner or permission password then youll see the word Secured in the title bar when you open the file in the Adobe Reader. Now after understanding about PDF password s let talk about the method to break or crack them. If youre dealing with a user password then let me tell you that it is next to impossible to crack the user password.
