AutomateTheBoringStuff.Ch13.Projects.P1_encryptPDFparanoia module¶

Encrypt PDF paranoia

Using os.walk(), write a script that will go through every PDF in a folder (and its subfolders) and encrypt the PDFs using a password provided on the command line. 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.

Notes

Default folder is parent directory.
Default suffix is ‘_encrypted.pdf’.
Running in debug mode, uncomment to delete original file.

AutomateTheBoringStuff.Ch13.Projects.P4_PDFbreaker module¶

PDF breaker

Say you have an encrypted PDF that you have forgotten the password to, but you remember it was a single English word. Trying to guess your forgotten password is quite a boring task. Instead you can write a program that will decrypt the PDF by trying every possible English word until it finds one that works.

Create a list of word strings by reading dictionary.txt. Then loop over each word in this list, passing it to PyPDF2.PdfFileReader.decrypt(). If this method returns the integer 0, the password was wrong and your program should continue to the next password. If PyPDF2.PdfFileReader.decrypt() returns 1, then your program should break out of the loop and print the hacked password. You should try both the uppercase and lowercase form of each word.
