Manage MID Server encryption keypairs Automation credentials are secured by encrypting them in the instance with the MID Server’s trusted public key prior to transmission. When the MID Server is created, it generates a keypair, consisting of a public and private key. After the MID Server is validated it can use the private key to decrypt automation credentials. Use these procedures to manage the keypairs generated for your MID Server and protect the automation credentials in your system. Rekey a MID ServerRotate the MID Server keypairs, if necessary, to satisfy your organization's security requirements.Invalidate a MID ServerInvalidate a MID Server you suspect has been compromised to prevent it from accessing automation credentials in the instance or executing outbound ECC probes.
