How do I chain a SSL certificate for my IEA appliance?
When you receive the new certificate, you will want to "chain" it. This takes the certificate of the CA you used and puts it in the same file as the certificate you received. This ensures that the IEA will trust your certificate even if it does not recognize the CA you used.
Double-click on the certificate to bring up the Certificate Import Wizard.
Click the Certification Path tab.
Select the CA that is immediately above your certificate.
Click the View Certificate button to open this certificate.
On the Details tab of this new window, click the Copy to File button.
When prompted, choose to save the file as base64. Perform this action for all three certificates on the Certification Path tab.
Using a text editor, open the first saved certificate, and save it (this is your IEA certificate).
Using another instance of your text editor, open the second and third certificates, then copy and the paste the text of these certificates into the first text file you created in step 7.
Note: Make sure the text "END CERTIFICATE" and "BEGIN CERTIFICATE" separate the text of the certificates.
