PyPDF2.utils.PdfReadError: File has not been decrypted

I have been learning Python PyPDF2, This was the code on geeksforgeeks.org/

# importing required modules
import PyPDF2

# creating a pdf file object
pdfFileObj = open('English.pdf', 'rb')

# creating a pdf reader object
pdfReader = PyPDF2.PdfFileReader(pdfFileObj)

# printing number of pages in pdf file
print(pdfReader.numPages)

# creating a page object
pageObj = pdfReader.getPage(0)

# extracting text from page
print(pageObj.extractText())

# closing the pdf file object
pdfFileObj.close()

After running this program, this error pops up:

Traceback (most recent call last):
File "C:\Program Files (x86)\Python38-32\lib\site-packages\PyPDF2\pdf.py", line 1147, in getNumPages
  self.decrypt('')
File "C:\Program Files (x86)\Python38-32\lib\site-packages\PyPDF2\pdf.py", line 1987, in decrypt  
  return self._decrypt(password)
File "C:\Program Files (x86)\Python38-32\lib\site-packages\PyPDF2\pdf.py", line 1996, in _decrypt 
  raise NotImplementedError("only algorithm code 1 and 2 are supported")
NotImplementedError: only algorithm code 1 and 2 are supported

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "main.py", line 11, in <module>
  print(pdfReader.getNumPages())
File "C:\Program Files (x86)\Python38-32\lib\site-packages\PyPDF2\pdf.py", line 1150, in getNumPages
  raise utils.PdfReadError("File has not been decrypted")
PyPDF2.utils.PdfReadError: File has not been decrypted

I tried different ways to resolve this, but this error stays, can you please guide me here?

PyPDF2 only supports very old PDF files. It doesn't support the formats from Acrobat 6. You'll either need to convert this to an older format or find a different PDF library.
