[英]PyPDF2 error "PyCryptodome is required for AES algorithm"
我有数百个需要设置密码的 PDF。 我尝试使用 pyPDF2 来执行此操作,但出现错误:“DependencyError:AES 算法需要 PyCryptodome”。
我试图用谷歌搜索任何其他模块,如 pikepdf,但我只发现如何使用它来破解密码,而不是实际设置密码。
任何想法如何处理它? 我在该行收到错误:“ input_pdf = PdfFileReader(in_file) ”
file = directory + '\\passwords.xlsx'
df = pd.read_excel(file)
df['PDF'] = df.iloc[:,[0]] + '.pdf'
df = df.to_dict('records')
for i in df:
filename = i['PDF']
password = i['Password']
with open(filename, "rb") as in_file:
input_pdf = PdfFileReader(in_file)
output_pdf = PdfFileWriter()
output_pdf.appendPagesFromReader(input_pdf)
output_pdf.encrypt(password)
with open(filename, "wb") as out_file:
output_pdf.write(out_file)

import PyPDF2
#pdf_in_file = open("simple.pdf",'rb')
pdf_in_file = open("gre_research_validity_data.pdf",'rb')
inputpdf = PyPDF2.PdfFileReader(pdf_in_file)
pages_no = inputpdf.numPages
output = PyPDF2.PdfFileWriter()
for i in range(pages_no):
inputpdf = PyPDF2.PdfFileReader(pdf_in_file)
output.addPage(inputpdf.getPage(i))
output.encrypt('password')
#with open("simple_password_protected.pdf", "wb") as outputStream:
with open("gre_research_validity_data_password_protected.pdf", "wb") as outputStream:
output.write(outputStream)
pdf_in_file.close()
类似错误消息的解决方案,但在计数页面期间 - https://dailydevsblog.com/troubleshoot/solved-not-able-to-find-number-of-pages-of-pdf-using-python-3-x-dependencyerror- pycryptodome-is-required-for-aes-algorithm-221411/
原始代码
! pip install PyPDF2
! pip install pycryptodome
from PyPDF2 import PdfFileReader
from Crypto.Cipher import AES
if PdfFileReader('Media Downloaded Files/spk-10-3144 bro.pdf').isEncrypted:
print('This file is encrypted.')
else:
print(PdfFileReader('Media Downloaded Files/spk-10-3144-bro.pdf').numPages)
使固定
! pip install pikepdf
from pikepdf import Pdf
pdf = Pdf.open('Media Downloaded Files/spk-10-3144-bro.pdf')
len(pdf.pages)
