4. Click OK to enter the new encrypted certificate information and save it to the Master or click
Cancel to void any changes made within this tab and exit without making changes to the target
Master.
A certificate consists of two different Keys:
Master Key is generated by the Master and is incorporated into the text string sent to the
CA during a certificate request. It is specific to a particular request made on a specific
Master.
Public Key is part of the text string that is returned from the CA as part of an approved
SSL Server Certificate. This public key is based off the submitted Master key from the
original request.
Regenerating a previously requested and installed certificate, invalidates the
previously purchased certificate because the Master Key has been changed.
5. Use the Display Certificate option to confirm that the new certificate was imported properly to
the target Master.

Once a certificate has been purchased from an external CA and then installed onto a
specific Master, DO NOT regenerate the certificate or alter its properties
(example: bit length, city, etc.).If the purchased certificate is regenerated, it becomes
invalid.
By default, the Display Certificate Action is selected and these fields are populated
with information from an installed certificate. If the Master does not have a previously
installed certificate, these fields are blank.
