crack_password(file, chars, processes=4, minlen=None, maxlen=None, verbose=True)
Attempt to crack a PDF password using a brute-force approach.
Args:
file (str): Path to the encrypted PDF file.
chars (iterable): List of characters to generate passwords from.
processes (int, optional): Number of parallel processes for password cracking. Defaults to 4.
minlen (int, optional): Minimum length of generated passwords. Defaults to 1.
maxlen (int, optional): Maximum length of generated passwords. Defaults to length of chars + 1.
verbose (bool, optional): Whether to display progress information. Defaults to True.
Returns:
str: Cracked password if successful, None if not successful
get_pdfdf(path, normalize_content=False, **kwargs)
Extract structured data from a PDF document and return it as a pandas DataFrame.
Args:
path (str): Path to the PDF file.
normalize_content (bool, optional): Whether to normalize content extraction. Defaults to False.
**kwargs: Additional keyword arguments for pikepdf.open and extract_pages methods.
Returns:
pandas.DataFrame: DataFrame containing extracted structured data from the PDF.
put_password_encryption(inputfile, outputfile, password)
Encrypt a PDF file using a specified password.
Args:
inputfile (str): Path to the input PDF file.
outputfile (str): Path to the output encrypted PDF file.
password (str): Password for encryption.
remove_restrictions(inputfile, outputfile, **kwargs)
Remove encryption and restrictions from a PDF file.
Args:
inputfile (str): Path to the input encrypted PDF file.
outputfile (str): Path to the output decrypted PDF file.
**kwargs: Additional keyword arguments for pikepdf.save method.
