我写了一个pdf破解,找到了被保护的pdf文件的密码.我想用 Python 编写一个程序,可以在没有密码的情况下在屏幕上显示该 pdf 文件.我使用 PyPDF 库.我知道如何在没有密码的情况下打开文件,但不知道受保护的文件.知道吗?谢谢
I write a pdf cracking and found the password of the protected pdf file. I want to write a program in Python that can display that pdf file on the screen without password.I use the PyPDF library. I know how to open a file without the password, but can't figure out the protected one.Any idea? Thanks
filePath = raw_input()
password = 'abc'
if sys.platform.startswith('linux'):
subprocess.call(["xdg-open", filePath])
KL84给出的方法基本可以,但是代码不正确(每页都写输出文件).清理后的版本在这里:
The approach shown by KL84 basically works, but the code is not correct (it writes the output file for each page). A cleaned up version is here:

# Decrypt password-protected PDF in Python.
#
# Requirements:
# pip install PyPDF2
from PyPDF2 import PdfFileReader, PdfFileWriter
def decrypt_pdf(input_path, output_path, password):
with open(input_path, 'rb') as input_file,
open(output_path, 'wb') as output_file:
reader = PdfFileReader(input_file)
reader.decrypt(password)
writer = PdfFileWriter()
for i in range(reader.getNumPages()):
writer.addPage(reader.getPage(i))
writer.write(output_file)
if __name__ == '__main__':
# example usage:
decrypt_pdf('encrypted.pdf', 'decrypted.pdf', 'secret_password')
