Transmitting secure information

12) A system comprising:

• a connection establisher to establish a secure connection between a boot environment and an admin node on a special port of the admin node, wherein connection information, including an authentication key, for the secure connection is preloaded into the boot environment;
• a secure key receiver to receive a secure key from the admin node over the secure connection in response to a verification by the admin node that a new node is marked for installation, wherein the secure key is for nodes marked for installation;
• a bundle receiver to:
• request a secure bundle corresponding to the new node, and
• receive, at a memory of the boot environment, a secure bundle from the admin node, the secure bundle corresponding to the new node;
• a bundle decrypter to decrypt the secure bundle using the secure key;
• and
• an image manager to install an installation image for the new node, wherein the installation image does not contain the secure information.

17) A non-transitory machine-readable storage medium encoded with instructions, the instructions executable by a processor of a system to cause the system to:

• establish a secure connection with a boot environment on a special port of an admin node, wherein an authentication key for the secure connection is preloaded into the boot environment;
• determine, by the admin node,
• that a new node is marked for installation;
• transmit a secure key to the new node over the secure connection;
• receive, in response to the determination that the new node is marked for installation, a request from the boot environment to transmit a secure bundle to a memory of the boot environment wherein the secure bundle contains secure information, protected by the secure key, that is not included in an installation image for the new node;
• and
• transmit the secure bundle to the memory of the boot environment.
