How to Crack password-protected PDF Files?A secure PDF file enforces copyright laws with features to prevent reproduction or distribution by other users. There are basically two types of PDF protection – One is password-based encryption and the other user accessibility restriction.
A) User accessibility restriction is that the original PDF creator can either restrict opening the PDF file itself or he can restrict others from modifying, printing or copying text and graphics from the PDF file. Simply put, “user” password protection and “owner” password protection. First one prevents opening a document without knowing the password. The second protects information in a document from being printed, copied or edited. (i) When you can view the pdf but there are Copying or Printing Restrictions Removing this type of “protection” is easiest because the security entirely depends on the pdf reader to honour those limitations. You can always use custom pdf readers who do not honour the restrictions.

There is also a number of tools available online which can remove such restrictions on the file. The software will use methods like Brute Force, Key Search and Dictionary Attack to guess the password. They will try to use all possible character combinations as the password and so the process might take hours or even days and would really depend on your computer’s processing power. B) Password-based encryption, however, is not easy to remove. The contents of the file are encrypted and you would need the correct password to decrypt the contents. There is no bypassing.

The Older version of pdf used a weak 40/128 bit RC4 algorithm. Newer versions use the stronger Rijndael (AES actually) with larger key lengths. Hence cracking pdf passwords by brute force, dictionary attacks may be feasible for old versions of pdf, but definitely not for the newer versions. Unless you have some information about the password, such as the number of characters, starting/ending etc you are out of luck.
