    Abstract: Examples described herein relate to a system and method for providing a key store within Baseboard Management Controller (BMC) of a computing device. A secure storage key of the BMC may include a key store, storing cryptographic objects such as cryptographic keys and digital certificates used by entities for performing cryptographic operations. The BMC may receive a request from an entity for performing the cryptographic operation and may determine if the entity is authorized to request the cryptographic operation. If the entity is authorized, the BMC may identify a private key from the key store for performing the cryptographic operation. Once the key is identified, the BMC may determine if the entity is permitted access to the private key. When the entity is permitted to access the private key, the BMC may perform the cryptographic operation using the private key and returns the results to the entity.

    Abstract: Example implementations relate to system and method of signing a boot information file by a manageability controller, and interlocking host computing system to signed boot information file. The boot information file may include a boot loader file and/or an OS kernel file of the host computing system. The manageability controller receives the boot information file from a processor of a computing device. Further, the manageability controller signs the boot information file with a hashed data of a unique identifier, to generate and communicate the signed boot information file to the processor. Later, the manageability controller updates a boot database stored in non-volatile random-access memory of a firmware engine of the host computing system with a thumbprint data of the signed boot information file to interlock the host computing system to the signed boot information file, in response to successful download of the signed boot information file by the processor.

    Abstract: Examples described herein relate to a manageability controller for controlling a display of a screen video. The manageability controller may receive screen video data from a hypervisor running on a host operating system (OS) that is executable by a main processing resource separate from the manageability processing resource. The screen video data may include a host OS screen video data corresponding to the host OS, a virtual machine (VM) screen video data corresponding to a VM running on the hypervisor, or both. Further, the manageability controller may store the host OS screen video data or the VM screen video data in a physical video memory based on a screen selection input.
