title: How to decode a pdf encrypted file from python
body: <p>I have got a PDF file and associated password.</p>
  
  <p>I would to convert an encrypted file to a clear version using python only.</p>
  
  <p>I found <a href="https://stackoverflow.com/questions/6413441/python-pdf-library">here</a> some python modules (pyPdf2 , PDFMiner)
