title: what is the difference between .cer & pfx file
body: <p>People used to say -</p>
  
  <p>cer - certificate stored in the X.509 standard format. This certificate contains information about the certificate's owner... along with public and private keys.</p>
  
  <p>pfx - stands for personal exchange format. It is used to exchange public and private objects in a single file. A pfx file can be created from .cer file. Can also be used to create a Software Publisher Certificate.</p>
  
  <p>** got ref from this link <a href="https://stackoverflow.com/questions/2292495/what-is-the-difference-between-a-cer-pvk-and-pfx-file">What is the difference between a cer, pvk, and pfx file?</a> **</p>
  
  <p>but nobody is saying when we should use CERT file and when we should use PFX file. If possible please discuss the situation when we should go for CERT file &amp; when we should go for PFX file. Thanks.</p>
