Abstract
In some examples, a device receives a plurality of encryption keys from a secure storage of a management controller, where a first encryption key of the plurality of encryption keys is for site-wide access of information on removable storage media plugged into respective computers of a site, and a second encryption key of the plurality of encryption keys is to restrict access of information on removable storage media plugged into a subset of the computers. The device uses a given encryption key of the plurality of encryption keys to encrypt information written to or decrypt information read from a first removable storage medium plugged into a first computer of the computers, wherein the management controller is associated with and is separate from a processor of the first computer.
