THE INFORMATION IN THIS ARTICLE APPLIES TO:
Unable to import a certificate into EFT because it does not use a passphrase and/or it is missing the private key.
EFT requires three items to successfully implement an SSL certificate: The certificate, private key, and passphrase.
A .pfx file will usually contain both the certificate and private key.
If the .pfx certificate was created in IIS, it most likely does not have a passphrase associated with it. You can export the corresponding private key and create a passphrase from within IIS.
Refer to the attached PDF for the procedure.
