To modify the certificates included in a chain, remove the certificates from the key pair and add them again. Alternatively, delete the certificate and recreate it by importing a new certificate file and adding certificates to the key pair.

To add a certificate to an existing key pair:

  1. Click Security and then go to Key Pairs > Key Pairs.
  2. Click to expand an existing key pair.
  3. In the Key Pair Chain Certificate list, select Add Certificate.
  4. To browse for and select the certificate file, click Choose File.
  5. Click Add.
