You will need to run the following command with open SSL ( available from openssl.org)
openssl pkcs12 -in mypfxfile.pfx -out outputfile.txt –nodes
This will produce a file that contains the Private key and all the SSL certificates contained within the PFX file
(please note it is recommended that you select the option to include all the certificates in the certification path when creating the PFX file for use on apache.)
You will then need to copy out the relevant pieces of information and create the following files from the outputfile.txt you created above for use with apache.
your private key file
your certificate file
your CA file / files
