Export a .p12 SSL Certificate from Windows

When the FileWave Server certificate and private key were created on Windows, export them as a password-protected PKCS #12 bundle for upload in FileWave Central > Preferences > Mobile. The bundle should contain the private key, server certificate, and available intermediate and root certificates. Windows saves the bundle with a 
.pfx extension; rename it to 
.p12 without changing its contents before upload.
Protect the exported bundle.
A 
.p12 file contains the server's private key. Use a strong temporary export password, transfer the file through an approved secure method, and remove unnecessary desktop or transfer copies after FileWave accepts the certificate.
Export the certificate and private key
Open a Run dialog and enter "mmc".
Go to File > Add/Remove Snap-in.
Add the Certificates snap-in and click the Add > button in the middle.
Choose Computer account.
Pick Local computer and click Finish.
Click the OK button.
In the MMC console browse to Certificates (Local Computer) > Personal > Certificates on the left. If your certificate is not there, browse the rest of the Certificates (Local Computer) tree until you find it.
Select your certificate in the middle pane, right-click, and pick All Tasks > Export.
When prompted, choose Yes, export the private key. If that option is unavailable, the selected certificate does not have an exportable private key on this computer; return to the system where the CSR and private key were created.
Under Personal Information Exchange - PKCS #12 (.PFX), check Include all certificates in the certification path if possible. Leave the other two checkboxes unchecked.
Choose Next and set a strong export password. FileWave Central prompts for this password during upload.
Save the 
.pfx file to a temporary secured location.
Rename the extension from 
.pfx to 
.p12.
Upload the 
.p12 file in FileWave Central > Preferences > Mobile, enter the export password, and verify that the expected certificate is shown before deleting temporary copies.
