The Problem of PDF Password
It would be frustrating when we want to view or edit PDF documents but only found that they are protected by PDF Password. The most commonly happened circumstance like these below:
1.When we click to open a PDF file by PDF Reader, a dialog box will pop up to ask me to input the password, but we have just forgotten it or have no idea about this.
2.We can read the PDF files in PDF Reader, but if we want to copy text from the document to clipboard or word, we only find that it doesn’t work.
3.We want to print PDF files by Printer, but it is also workless.
Often coming across the cases like mentioned above, it would come into our mind that we need to crack PDF Password to unlock them. However, in order to make this decryption more accurate and efficiency, we have to know something about PDF Password.
Two Common Types of PDF Password
1.PDF User Password: Also known as PDF Open Password. If a PDF file has been encrypted with PDF user password, you could not open it unless you know exactly what the password is.
2.PDF Owner Password: You can view all the contents of owner password protected PDF files. But the copy, paste, print permissions are locked. Generally, you can check out the Security Properties in Adobe PDF Reader. The copy and print function are not allowed.
