Converting key and certificate files to .pfx file

Published August 20, 2014 5:33 pm

A quick search on net will give you openssl pkcs12 command to achieve this.


  1. download openssl if you don’t have already.
  2. inputs – private rsa key. If you have encoded text from the webhost, save it in a text file. I put it in a private.key
  3. inputs – domain key – I received a .crt file for this.
  4. inputs – I received 2 intermediate certificates and one root certificates – all .crt files
  5. command line – openssl pkcs12 -export -out a.pfx -inkey private.key -in domainkey.crt -certfile f1.crt -certfile f2.crt -certfile root.crt
  6. this did the trick to get the .pfx file.
  7. openssl asked for password to protect the pfx file
