What are PDF files?
They are those files downloaded from the Internet that are accessed in Adobe Acrobat.
Although oftentimes these PDF files can be overflowing with important information, if they are encrypted you cannot do anything with them. It is vital to know the password!
The two different PDF password types are the user password and the owner password. These passwords offer different kinds of protection. User passwords must be established before the creation of the PDF file; if a PDF has a user password, then the file can only be accessed by entering that password.
An owner password will ensure that those who don't know the password cannot modify or print the file. There are many ways to remove the password in case the password has been lost. A slow method would be the Brute Force Attack. More methods exist, however, and many of them are quicker if someone has used an easily crackable password.
When you are searching for a PDF password cracker program, beware of the free options as these are often limited to displaying only part of the recovered password until you pay up for the full version. Sometimes it's possible to guess the real password but oftentimes these programs are designed to make that as hard as possible unless you buy the full version.
