Encryption

Sensitive information such as tokens and passwords are stored encrypted on the SDN Controller. However, to encrypt and decrypt these properties, the controller requires a master key that is passed into the controller upstart script via an environment variable. To change the default master key (recommended):

  1. First, stop these services:

    sudo service sdnc stop

    sudo service sdna stop

  2. Then change the default master key:

    sudo /opt/sdn/admin/sdnpass old_master_key new_master_key
