12.2. Validating your SSH key size

Procedure

1. Validate your SSH key size:

   ssh-keygen -l -f /home/stack/overcloud-deploy/overcloud/ssh_private_key

   Example output:

   1024 SHA256:Xqz0Xz0/aJua6B3qRD7VsLr6n/V3zhmnGSkcFR6FlJw stack@director.example.local (RSA)

2. If your SSH key is less than 2048 bits, you must rotate out the SSH key before continuing. For more information, see Updating SSH keys in your OpenStack environment in Hardening Red Hat OpenStack Platform.
