For example, say your PDF is a three-page excerpt from a longer report, and its pages are numbered 42, 43, and 44. To get the first page of this document, you would want to call pdfReader.getPage(0), not getPage(42) or getPage(1).Once you have your Page object, call its extractText() method to return a string of the page’s text ➌. The text extraction isn’t perfect: The text Charles E. “Chas” Roemer, President from the PDF is absent from the string returned by extractText(), and the spacing is sometimes off. Still, this approximation of the PDF text content may be good enough for your program.

Save each encrypted PDF with an _encrypted.pdf suffix added to the original filename. Before deleting the original file, have the program attempt to read and decrypt the file to ensure that it was encrypted correctly.Then, write a program that finds all encrypted PDFs in a folder (and its subfolders) and creates a decrypted copy of the PDF using a provided password. If the password is incorrect, the program should print a message to the user and continue to the next PDF.

Since Python-Docx can use only those styles that already exist in the Word document, you will have to first add these styles to a blank Word file and then open that file with Python-Docx. There should be one invitation per page in the resulting Word document, so call add_break() to add a page break after the last paragraph of each invitation. This way, you will need to open only one Word document to print all of the invitations at once.

Using the file-reading skills you learned in , create a list of word strings by reading this file. Then loop over each word in this list, passing it to the decrypt() method. If this method returns the integer 0, the password was wrong and your program should continue to the next password. If decrypt() returns 1, then your program should break out of the loop and print the hacked password. You should try both the uppercase and lower-case form of each word. (On my laptop, going through all 88,000 uppercase and lowercase words from the dictionary file takes a couple of minutes. This is why you shouldn’t use a simple English word for your passwords.)
