SDDC Certificate Tool

Replacing SSL certificates across VMware products is a manual and time-consuming process. The SDDC Certificate Tool automates this workflow and makes it easy to keep certificates across your SDDC up to date. It will replace all certificates in the supported products and reestablish trust between the components.

Simple Workflow

Note: See PDF for detailed instructions.

This workflow is only if you already have signed certificates that you want to replace on VMware components.

  1. Copy signed certificates, private keys, and the certificate authority chain from your Certificate Signing Authority to a Linux server. A private folder is recommended to safeguard the private keys.
  2. Download and extract the SDDC Certificate Tool to the /opt/vmware/cert-mgmt/ folder.
  3. Follow a configuration template and edit it to match your environment. Follow the examples at /opt/vmware/cert-mgmt/config and the Configuration File section for a detailed look.
  4. Run Certificate Replacement command.
    java -jar lib/certreplace-*.jar -c config/config.json -replacecert - passwordEntry

  5. If there are any errors in the configuration file, they will be shown and certificate replacement will only proceed once all errors have been fixed.
